Summary 

These Avalonia support terms and conditions ("Support Terms") set forth the legal framework under which Avalonia UI (AvaloniaUI OÜ) provides support services (as herein defined) to the Customer.

1. DEFINITIONS  

"Application Code" shall mean a computer software program written strictly using the Avalonia framework in C#, by or for the Customer, with a user interface, enabling the Customer or their users to accomplish a specific task and display any results of the task on the display monitor or screen.

“Avalonia Accelerate” refers to Avalonia UI’s commercial licensing and subscription programme providing developer tooling, components, and additional functionality for the Avalonia framework. Avalonia Accelerate is offered in four tiers, Community, Indie, Business, and Enterprise. Each tier is governed by its applicable licence terms. For the purposes of these Support Terms, a valid Avalonia Accelerate licence means any active licence issued by Avalonia UI under the Business or Enterprise tiers, or other paid tier as designated by Avalonia UI. Developers within an organisation who use the Community or Indie editions of Avalonia Accelerate in connection with projects covered by a Support Agreement are deemed out of compliance with these Support Terms, even if such usage occurs under personal accounts or unlinked email addresses.

"Avalonia Account" shall mean the user account registered on our Customer Portal used by a Designated User to access support services, manage licences, and submit support requests.

"Business Day" shall mean standard working days between Monday and Friday with the exception of major public holidays in the region from where Support is provided.

"Customer Portal" shall mean Avalonia's web-based service accessible via an Avalonia Account, located at a URL designated by Avalonia UI, used for subscription and licence management, documentation access, and other account-related services.

"Designated User" refers to a single, distinct person for whom a support agreement has been purchased and who has been assigned a seat in the Customer Portal via their Avalonia Account. A Designated User must hold a valid Avalonia Accelerate licence linked to the Customer’s organisation.

"Development Team" refers to all developers working on an application that uses Avalonia UI package(s), including developers not responsible for UI development.

"Documentation" shall mean documentation available at docs.avaloniaui.net or other locations designated by Avalonia UI. Separate Documentation is available for each Major and Minor release of Avalonia.

"Effective Date" shall be the date this agreement is signed by all parties.

"Errors" shall mean an error, flaw, mistake, failure or fault in packages developed by Avalonia UI that prevents it from behaving as described in the relevant Documentation or as agreed between the parties.

"Extended Support" shall mean a continuation to the normal Support period, which allows Designated Users to receive selected Support (Business Support or Enterprise Support) for a version of Avalonia UI that is no longer generally supported by Avalonia UI. Extended Support is mandatory for customers with active support agreements who continue to develop or maintain products on older Avalonia versions.

"Install Support" shall mean Support that is limited to installation-related Error(s) on Development Platforms specified as supported host platforms for each Avalonia release under Documentation.

"Maintenance Release" shall mean a release or version of Avalonia containing bug fixes, error corrections and other changes targeted to maintaining and improving product stability and quality. Maintenance Releases are generally depicted as a change to the third digit of the package version number.

"Major Version" shall mean the first digit in a three-digit semantic versioning scheme (X.y.z) representing significant changes, enhancements, or adjustments in the software, often introducing potential incompatibilities with prior versions.

"Platforms" shall mean both Development Platforms and Deployment Platforms. Supported host and target Platforms may vary for each Avalonia release as defined under Documentation.

"Pre-Release Functionality" shall mean software provided for testing, preview, check or validation purposes. Pre-Release Functionality in features or releases may be labeled as "Alpha", "Beta", "Technology Preview", "Preview", "Release Candidate", or other such explicit terminology defining that the software may not yet be ready for production or covered under Support. Pre-Release Functionality may also be discontinued or deprecated without further notice.

"Enterprise Support" shall mean an upgraded level of Support that Avalonia UI provides pursuant to these Support Terms to the Customer if the Customer has purchased Enterprise Support instead of Business Support.

"Business Support" shall mean the basic level of Support that Avalonia UI provides pursuant to these Support Terms to the Customer.

"Response Time" shall mean the period of time from when the Customer notifies Avalonia UI about an Error or Support request until Avalonia UI provides the Customer with a response that addresses (but does not necessarily resolve) the reported Error or provides the requested Support.

"Security Issue" shall mean an Error that causes or reasonably could cause a vulnerability in a system or application that uses Avalonia UI where such vulnerability can or reasonably could impact the privacy and security of the system or application.

"Security Fix" shall mean a patch, workaround, best practice documentation, or other method as reasonably determined by Avalonia UI to address a verified Security Issue.

"Subscription" refers to what the Customer purchases from Avalonia UI to access the Support Services.

"Support" shall mean developer assistance that is provided by Avalonia UI to assist eligible Designated Users in installation, usage and functionality problem resolution for Error(s) and Error workarounds pursuant to the terms of these Support Terms.

"Support Portal" shall mean Avalonia's web-based service and support interface accessible via an Avalonia Account, located at a URL designated by Avalonia UI, used for support ticket submission, and other support-related services.

"Support Validity Term" shall mean the fixed time period agreed between the Parties during which time the Customer is eligible to receive Support from Avalonia UI, with a minimum term of twelve (12) months.

2. SUPPORT SERVICES

2.1 Support Services Provided by Avalonia UI

Subject to these Support Terms and during the Support Validity Term, Avalonia UI will, via the Customer Portal and email (support@avaloniaui.net), provide Designated User(s) with Support for Avalonia.

Support is provided exclusively for projects written in C#. Avalonia UI does not offer support for applications built with F# or VB.NET, as guidance is tailored specifically for C# development.

Avalonia UI will make commercially reasonable efforts to solve any Errors reported by Designated User(s). Resolution of an Error may be provided through the Designated User(s) themselves downloading a later released version of the applicable Avalonia UI package(s) or providing the Designated User with a fix, workaround or other solution Avalonia UI deems reasonable.

Confirmed bugs in Avalonia UI that affect Customer's project will be prioritized internally and Avalonia UI will either provide a workaround or a patch. Enterprise Support customers receive priority handling and direct escalation to our engineering team for critical issues.

2.2 Subscribers Obligations

To report an Error, the Designated User shall register the Error on the Support Portal using their Avalonia Account. The Designated User must have been assigned a support seat in the Customer Portal before they can raise tickets.

The Designated User must provide adequate information and documentation to Avalonia UI to enable it to recreate the Error or problem for which the Designated User has sought assistance.

To ensure efficient handling of Errors, the Designated User must provide the following information, where relevant:

• A clear, detailed description of the problem, question or suggestion

• Marking the issue as a Security Issue, when reporting a Security Issue

• Identification of which Avalonia UI package and version is affected

• Identification of the operating environment (e.g. operating system, runtime, hardware platform, etc.) on which the problem exists

• A complete and compilable test case of not more than 500 lines of code that demonstrates the problem. Failure to provide a test case will relieve Avalonia UI from performing Support Services

• Additional relevant content, such as screenshots, traces, logs, etc.

Additional content should be included as attachments. The preferred image formats are JPEG and PNG. Compressed content should be included in zip or tar.gz archives. Executable content and documents in platform-specific formats such as Microsoft Office® are not accepted.

For Avalonia UI to provide prompt handling of Errors, the Designated User shall promptly respond to any requests from Avalonia UI for additional information.

2.3 Support Limitations 

General limitations: 

Support will be aligned with the major version available at the time of the purchase. Specifically, if a Development Team secures support during the tenure of version 11.x.x, they will receive support for that version and any subsequent major releases, but not for preceding versions such as 10.x.x. For clarity, if Avalonia UI releases version 12.0.0 while a customer's support agreement is in effect, that customer may seek support for both versions 11.x.x and 12.x.x. Upon the agreement's renewal, however, support will be limited to the latest major version, in this instance 12.x.x. Should a customer wish to maintain support for earlier major versions post-renewal, they would need to opt for Extended Support.

Avalonia UI shall only provide Support for Designated User(s) who have been properly assigned seats in the Customer Portal. Each developer holding a valid Avalonia Accelerate licence, as defined in Section 1, must be covered under the corresponding Support agreement.

Support tiers must correspond to the Avalonia Accelerate licence tier held by the Customer. 

Support is not provided for Pre-Release Functionality, including preview releases, beta releases, release candidates, or any features labeled as "Alpha", "Beta", "Technology Preview", or similar terminology.

Support is not provided for forks of Avalonia UI or for Errors on platforms not officially supported as documented in the Documentation.

Avalonia UI shall have no obligation to provide Support for hardware or operating system-specific problems or problems arising from improper use, accident, neglect or modification of Avalonia UI.

Limitations with Install Support: 

Support is limited to Error(s) regarding the installation and setting up of the Avalonia development environment on host Platforms.

Limitations with Business Support: 

Business Support includes twelve (12) support requests ("Tickets") per Designated User per twelve (12) month Support Term. 

If the allocated Tickets are exhausted before the end of the Support Term, Avalonia UI may, at its discretion, provide additional support under its standard hourly development services terms. As of November 2025, the applicable rate is €245.00 per hour. This rate is subject to change at Avalonia UI's discretion, and any changes do not require an amendment to this Agreement. Prior to commencing chargeable work, Avalonia UI will notify the Customer, provide an upper-bound estimate of time and cost, and obtain the Customer's written agreement to proceed.

For the purposes of this clause, all support interactions, including those that result in the identification of an Error in Avalonia UI, will be counted towards the Customer's Ticket allocation. Bug reports are treated as support requests unless Avalonia UI determines, at its sole discretion, that the issue is systemic, high-impact, and broadly applicable to other customers. Examples of issues that would typically not count against the Ticket allocation include:

• Defects in core Avalonia framework functionality that affect many users

• Critical compatibility issues with officially supported platforms or widely-used packages

• Security Issues as defined in Section 1

• Significant platform-specific failures that would impact a substantial portion of the user base

Unused Tickets do not carry forward to subsequent Support Terms.

Avalonia UI shall not provide Support for third-party software or problems caused by third-party software even if such third-party software is distributed together with Avalonia UI package(s).

Avalonia UI retains the discretion to modify the response times specified in Section 3 if a high volume of requests is received in a short time frame.

Avalonia UI shall only provide Support for Error(s) that are reported on and can be reproduced on supported Platforms.

Limitations with Enterprise Support: 

Enterprise Support includes unlimited tickets under normal usage patterns. 

Avalonia UI monitors the aggregate engineering hours allocated to each customer account to ensure service sustainability. If the average engineering hours per seat for a customer exceeds one hundred twenty percent (120%) of the average engineering hours per seat across all other Enterprise customers over any consecutive three (3) month period, Avalonia UI may suspend applicable response time commitments while reviewing the account's usage.

Where Avalonia UI reasonably concludes that the continued level of support would result in a material net loss or impose disproportionate cost relative to the Fees paid, Avalonia UI reserves the right to propose revised commercial terms or, if no agreement is reached, to terminate the Support Agreement with thirty (30) days’ written notice.

Avalonia UI shall not provide Support for third-party software or problems caused by third-party software. However, if such third-party software is distributed together with Avalonia, Avalonia UI will make commercially reasonable efforts to solve such problems.

Avalonia UI shall only provide Support for Error(s) that can be reproduced on supported Platforms. If the Error is on a Platform that is not supported, Avalonia UI will make commercially reasonable efforts to provide a solution on the closest corresponding supported Platform.

2.4 Extended Support

Extended Support extends the Support Validity Term for a release of Avalonia that is no longer generally supported.

Extended Support is mandatory for customers with active support agreements who continue to develop or maintain products on older Avalonia versions. It is acquired through an annual fee for each Designated User and necessitates specifying (i) the Avalonia version(s) and (ii) the used Platform(s) being employed.

Extended Support is specific to Customer's Avalonia Account and the identified versions and platforms.

2.5 Development Team Coverage Requirements

Support coverage must correspond to all developers holding a valid Avalonia Accelerate licence within the Customer’s organisation. Each licensed user must be included under the applicable support agreement for the corresponding tier.

Support may not be limited to a subset of licensed users for the purpose of reducing seat count. Designers, project managers, and other personnel who do not hold Avalonia Accelerate licences are not required to be covered.

2.6 Communication Channels

Support is provided through the following channels based on the support tier:

• Business Support: Email (support@avaloniaui.net) and Support Portal

• Enterprise Support: Email, Support Portal, and real-time Slack communication with our engineers

For critical issues, Enterprise customers may escalate through their dedicated Slack channel for immediate attention.
Business Support is provided during standard business hours: 09:00-17:00 Central European Time (CET), Monday through Friday, excluding Estonian public holidays.

Enterprise Support is provided during extended hours: 08:00-20:00 Central European Time (CET), Monday through Friday, excluding Estonian public holidays. Critical issues reported via Slack may receive after-hours response at Avalonia UI's discretion.

3. RESPONSE TIME

In performing Support, Avalonia UI shall commit to the following Response Times:

Business Support: Errors and Support requests will have a Response Time not to exceed five (5) Business Days.

Enterprise Support: Errors and Support requests will have a Response Time not to exceed one (1) Business Day.

Security Issues: Errors that are Security Issues will have a Response Time not to exceed one (1) Business Day for all support tiers.

For complex issues, Avalonia UI may provide an initial response to the Designated User and then follow up, without undue delay, with additional communication before an Error is properly addressed or Support is provided.

The customer acknowledges and understands that no software is perfect or error-free and that, despite Avalonia UI's commercially reasonable efforts, Avalonia UI may be unable to provide answers to or resolve some or all requests for Services. Avalonia UI makes no promises, guarantees, or assurances of any kind that it will be able to resolve all Customer Support requests.

4. ADDITIONAL SERVICES IN ENTERPRISE SUPPORT

The Designated User(s) can, on request, ask Avalonia UI to access their computer remotely to resolve problems directly. Where the Designated User requests that Avalonia UI remotely access their computer, the Designated User must have authority to grant Avalonia UI such remote access and Customer accepts that any remote access support is provided as-is and at Customer's own risk.

The Designated User(s) can request a one (1) hour kick-off session via video call, which shall automatically expire (regardless of whether redeemed by the Designated User) after two (2) months from the purchase of the Enterprise Support.

Enterprise Support includes access to video consultations via Google Meet. Video consultations must be booked at least one (1) Business Day in advance and are capped at a total of four (4) calls per Designated User per Support Validity Term. Video consultations are provided at Avalonia UI's discretion.

Enterprise Support includes quarterly check-in meetings with Avalonia engineers to help keep projects on track.

Enterprise Support includes real-time Slack communication with our engineers for faster collaboration.

Enterprise Support includes emergency bug fixes and access to our product roadmap.

All Enterprise Support requests will be handled with high priority.

5. MAINTENANCE RELEASES, UPDATES, AND UPGRADES 

The primary focus of Maintenance Releases is product quality.  Therefore, each Maintenance Release typically includes the following types of changes to the previous version of Avalonia:

• Bug fixes caused by changes to previously working code.

• Fixes related to build issues on supported Platforms.

• Error corrections specific to a single Platform that are not present on other Platforms.

• Critical Error corrections such as crashes, data corruption, loss of data, race conditions; and 

• Updates to documentation and licence information when deemed necessary by Avalonia UI. 

The primary focus of Updates is introducing new features to Avalonia and covering new platforms. Therefore, each Update typically includes the following types of changes to the previous version of Avalonia: 

• New platform support.

• New runtime support.

• New features. 

6. HANDLING OF SECURITY ISSUES

6.1 Reporting Security Issues

When reporting a Security Issue, the Designated User must mark the issue as a Security Issue in the Support Portal to ensure proper prioritization and handling.

6.2 Security Issue Assessment

Reported Errors marked as Security Issues will be assessed to determine the severity of the issue and to verify if it indeed is a valid Security Issue. The Designated User who reported the issue may be contacted for more details. If the reported issue is not deemed to be a Security Issue by Avalonia UI, it will be treated as a normal Error and handled accordingly.

6.3 Security Fix Delivery

A verified Security Issue will be fixed as soon as practically possible, dependent on the severity of the Security Issue. A notification via appropriate channels will be made along with patches for the currently supported versions of Avalonia UI, where applicable. A Security Fix for the Security Issue may be included in the next Maintenance Release of Avalonia UI.

6.4 Third-Party Security Issues

If the Security Issue is reported in a third-party library used in Avalonia UI, Avalonia UI will notify the relevant third party of such Security Issue detected in their library. If and when the Security Issue is resolved in the third-party library, the new version of the third-party library will be included in the next feasible Maintenance Release of Avalonia UI. If a fixed version of the third-party library is not available, Avalonia UI may instead provide documentation regarding the issue, or a patch for this third-party library.

6.5 Documentation of Security Issues

All verified Security Issues in Avalonia UI will be noted in Documentation.

7. WARRANTY DISCLAIMER 

Avalonia UI makes no warranties that the Support provided will be successful in resolving any difficulties or problems or in diagnosing Errors reported by the Customer. Support is provided to Customers on an "as is" basis. To the maximum extent permitted by applicable law, Avalonia UI disclaims all warranties and conditions, either express or implied, including, but not limited to, implied warranties of merchantability and fitness for a particular purpose for the Support provided by Avalonia UI to the Customer.

8. TERM & TERMINATION

8.1 Term

Support agreements have a minimum term of twelve (12) months. The term of this Agreement shall commence on the Effective Date and shall continue for a period of one (1) year unless agreed otherwise in the Purchase Order.

Renewal is not automatic. Near the end of the term, Avalonia UI will contact Customer to review coverage and send a renewal invoice for the next year. If Customer chooses not to renew, Customer will lose access to further support. Any renewal of Services will start from the previous expiry date and is payable at the applicable annual rate available on the Avalonia UI website or as quoted by Avalonia UI.

8.2 Termination for Breach

Avalonia UI may terminate this Agreement (i) in the event Customer fails to pay an invoice when due, (ii) in the event Customer commits a material breach of this Agreement and fails to remedy that breach within thirty (30) days of receipt of written notice of material breach, or (iii) as otherwise provided in this Agreement.

The Customer may terminate this Agreement in the event Avalonia UI commits a material breach of this Agreement and fails to remedy that breach within thirty (30) days of receipt of written notice of material breach.

9.4 Full Payment Responsibility

The Customer is obligated to remit the full amount specified on the invoice, free from any deductions including, but not limited to, withholding taxes and other local levies. All additional expenses related to such taxes or charges shall be solely borne by the Customer.

Where any Support under this Agreement involves the handling of personally identifiable data (e.g., in emails or metadata), all data will be processed in accordance with Avalonia UI's Privacy Policy and applicable data protection laws.

Customer acknowledges and consents that, in the course of delivering the Services, Avalonia UI may need to transmit Customer Information among its affiliates and/or subcontractors, which could be situated globally.

Avalonia UI does not provide data back-ups for services unless specifically stated otherwise.

11. AUDIT AND COMPLIANCE

11.1 Audit Rights

Avalonia UI reserves the right to verify the Customer’s compliance with these Support Terms, including the number of Avalonia Accelerate licences held by the Customer and corresponding Support coverage. Such verification may be performed through manual review or automated validation mechanisms in accordance with applicable data protection laws.

11.2 Attestation Requirement

Upon request, Customer must provide written attestation of the total number of active Avalonia Accelerate licences held during the Support Validity Term. This attestation must be signed by an authorised representative of the Customer.

11.3 Remediation

If an audit or attestation reveals that Customer holds more Avalonia Accelerate licences than are covered by Support, Customer shall promptly purchase additional Support seats to achieve full coverage and pay for the uncovered period at the then-current rates, plus any applicable interest or penalties.

12. MISCELLANEOUS

Export and Sanctions Laws. Customer agrees that Customer’s use of the Support will comply with all applicable export control and trade sanctions laws, rules and regulations, including the regulations promulgated by the U.S. Department of Commerce’s Bureau of Industry and Security (“BIS”) and the U.S. Department of the Treasury’s Office of Foreign Assets Control (“OFAC”) (collectively, "Export Laws"). Customer represents and warrants that Customer is not (i) located or resident in a country or territory that is subject to comprehensive U.S. trade sanctions or other significant trade restrictions (including, without limitation, Cuba, Iran, North Korea, Syria, and the Crimea region, Donetsk People’s Republic region, and Luhansk People’s Republic region of Ukraine) (collectively, the “Sanctioned Countries”); or (ii) identified on any U.S. government restricted party lists (including without limitation the Specially Designated Nationals and Blocked Persons List, Foreign Sanctions Evaders List, and Sectoral Sanctions Identifications List, administered by OFAC, and the Denied Party List, Entity List and Unverified List, administered by BIS) (collectively, the “Restricted Party Lists”). Customer further certifies that Customer will not, directly or indirectly, export, re-export, transfer or otherwise use the Support in violation of the Export Laws, or with any purpose prohibited by the same Export Laws, in any Sanctioned Country, to any person or entity on a Restricted Party List, or for any nuclear, chemical, missile or biological weapons-related end uses. Customer acknowledges that the Support, or any feature or part thereof, may not be available for use in all jurisdictions and that Customer is responsible for complying with applicable Export Laws wherever Customer uses the Support.

12.6 Severability

If any provision of this Agreement is held invalid or unenforceable for any reason but would be valid and enforceable if appropriately modified, then such provision will apply with the modification necessary to make it valid and enforceable.

If such provision cannot be so modified, the parties agree that such invalidity will not affect the validity of the remaining provisions of the Agreement; provided, however, that if Sections 7 and 9 cannot be modified to be valid and enforceable, this Agreement will be deemed invalid in its entirety.

12.7 Dispute Resolution

If Customer is not satisfied with the Services provided by Avalonia UI, Customer agrees to give Avalonia UI a written description of the problem(s) and to make a good faith effort to amicably resolve the problem with Avalonia UI before commencing any proceeding. Avalonia UI also agrees to make a good faith effort to amicably resolve any problem with the Customer before commencing any proceeding. No claim or action, regardless of form, arising out of this Agreement may be brought by either party more than one (1) year after the cause of action has accrued. 

12.8 Governing Law 

The parties agree that this Agreement is governed by the laws of England and Wales as mutual consent to the exclusive jurisdiction and venue in the courts of London, UK, and expressly disclaim the applicability of the laws of any other state or jurisdiction to the maximum extent possible. If either party employs solicitors to enforce any rights arising out of or relating to this Agreement, the prevailing party will be entitled to recover its reasonable solicitors' fees, costs, and other expenses, including the costs and fees incurred on appeal or in a bankruptcy or similar action.

12.9 Complete Agreement

This Agreement, including all addenda (if any) and all Orders, constitutes the entire agreement between the parties with respect to the subject matter hereof, and supersedes and replaces all prior or contemporaneous understandings or agreements, written or oral, regarding such subject matter. No amendment to, supplement or modification of this Agreement will be binding unless in writing and signed by duly authorized representatives of both Parties. In the case of conflicts, discrepancies, errors or omissions among the Agreement, any addenda, and any Order and/or Statement of Work, the documents and amendments to them shall take precedence and govern in the following order: (a) any Order and/or Statement of Work (with respect to that Order and/or Statement of Work only); (b) addenda (if any); and (c) this Agreement.

12.10 Amendment 

This Agreement may not be amended, supplemented or modified except by a written instrument signed by the parties hereto, which instrument makes specific reference to this Agreement. These Support Terms may be updated by Avalonia UI at renewal, provided that during the respective ongoing Support period, the level of Support may not be materially reduced without the consent of Customer.

12.11 Online Terms Updates 

Support Terms updates may be provided online via the Avalonia UI website. In the event that online Support Terms provide greater Support services to Customer than as set forth herein, then the online Support Terms shall apply.
