Frequently asked questions
Everything you need to know about Avalonia, our products, licensing, and support.
Licensing
Yes! Avalonia is free to use and open-source under the MIT licence. The code is available on GitHub, and packages can be downloaded from Nuget.
With Avalonia Plus, Pro, and Enterprise, you earn perpetual rights to the version of the software you've paid for. On an annual subscription, perpetual rights are granted immediately. On a monthly subscription, after 12 consecutive months of uninterrupted payment, the licence converts to perpetual. Once earned, you receive an Offline Licence Key that works without an internet connection.
If you've earned perpetual rights, you keep using the version you have — you just stop receiving updates. If you're on a monthly subscription that hasn't yet reached 12 months, your right to use the software ends at the end of the billing period.
This structure ensures fair pricing and appropriate terms for different use cases. Individual licences are priced for people purchasing with their own money. Organisation licences are structured for companies purchasing for their teams, with Named User management, reassignment, and compliance features.
No. Individual licences (Plus and Pro) require that the customer purchases with their own funds. If a third party pays or reimburses the fees, the licence grant is void. If your employer needs licences, they should purchase the Organisation variant.
Yes. All Pro and Enterprise licences include redistribution rights for the compiled (executable) form of the Components as part of your own applications. Your end users do not need separate licences or pay runtime fees. You may not distribute the Components as a standalone library.
No. Organisation licences (Plus, Pro, and Enterprise) allow installation on automated build machines and CI servers without a separate Named User licence, as long as the build server is used only for automated compilation, packaging, and deployment, and every individual who interactively uses the software holds a valid licence.
All tiers collect licensing and compliance telemetry. Usage analytics telemetry is collected by default but can be adjusted in paid tiers. The Community tier requires mandatory telemetry (including usage and interaction data) that cannot be disabled. Avalonia UI does not collect source code, application code, or proprietary business data.
