Open source you can count on
Avalonia is backed by sustainable revenue, a dedicated engineering team, and over a decade of continuous development. We invest in the framework because our business depends on it too.
Business model
How Avalonia stays independent
Many open-source projects depend on donations or volunteer goodwill. Avalonia doesn't. We generate revenue through commercial products and services that align with how enterprises already use the framework.
This means we can hire full-time engineers, invest in tooling, and commit to long-term roadmaps without compromising the open-source core.
Revenue
Four pillars of sustainable growth
Each revenue stream funds continued investment in the open-source framework. When you choose Avalonia's commercial products, you're directly strengthening the platform your applications depend on.
Avalonia
The free, open-source UI framework at the heart of everything we do. Paid tiers add professional tooling, UI components, and SLA-backed support.
XPF
A cross-platform fork of WPF that enables existing WPF applications to run on macOS, Linux, mobile, and web without rewrites — saving enterprises millions in cost and years of work.
Professional services
Expert consulting for complex migrations, architecture reviews, and custom implementations.
Corporate sponsorship
Strategic partnerships with companies like Devolutions that invest directly in Avalonia's roadmap.
Track record
Over a decade of continuous investment
Avalonia has been in active development since 2013. Over that time, the team has grown from a single contributor to 19 Avalonians shipping across 6 platforms.
That kind of sustained growth comes from a business model that works, not from grants or volunteer goodwill. The companies building on Avalonia today know the framework will be maintained for years to come.
