Understanding Individual vs Organization subscriptions.

An Organization subscription is purchased by a company, team, or other legal entity. Licences are managed centrally and can be assigned and reassigned to employees, contractors, or other team members as needed. If your company is buying Avalonia subscriptions for its people, Organization is the right choice.

Any legal entity — companies, non-profits, government agencies, or other organizations — that wants to provide Avalonia Plus or Pro to its people. Organization subscriptions include per-seat licensing that can be reassigned between team members, centralized license management, and access to the Enterprise tier with SLA, dedicated support, component source code, and quarterly technical check-ins.

Organization Plus and Pro subscriptions are priced per named seat. Each seat covers one developer, and a seat can be reassigned to another team member through the Customer Portal after a 90-day cooldown from its last assignment, for example when someone leaves the team or changes roles. The total number of developers using Plus or Pro at any given time must not exceed the number of purchased seats.

Organizations have four tiers: Avalonia (free, the open-source framework), Plus (advanced tooling, per seat), Pro (tooling plus premium components, per seat), and Enterprise (everything in Pro plus component source code, SLA, and dedicated support). The Enterprise tier is only available to organizations.

Enterprise is sold through an annual agreement for your organization. The annual base fee includes three Enterprise seats, and you add seats as your team grows. Additional seats are priced in volume bands (4 to 10, 11 to 25, and 26 onward), with lower rates in the higher bands. Every seat receives the full Enterprise benefits. The calculator on the Enterprise page shows your annual total in USD, EUR or GBP, and you can request a written quote with just your name and email.
