Three-Year Sponsorship Accelerates Avalonia’s Open-Source Roadmap

Avalonia has secured a three-year sponsorship that provides predictable funding exclusively for our open-source work while preserving our autonomy and MIT licence. The US $3 million commitment guarantees sustained effort on freely available improvements covering core framework development, documentation, tooling and community support, and every user benefits at no cost.

The sponsor is Devolutions, a Québec-based leader in remote connection management, including RDP and SSH, and Privileged Access Management (PAM), whose cross-platform solutions are built with Avalonia. David Hervieux, CEO of Devolutions, says:

Avalonia gives us the performance and flexibility to build robust, cross-platform PAM solutions without compromise. Supporting its open-source future ensures we can deliver secure, reliable tools—and give back to the ecosystem we rely on.

For Avalonia the agreement closes the classic open-source funding gap. Our revenue-generating services have kept us profitable, yet until now commercial work necessarily dictated the team’s priorities. The new funding removes that conflict. Adoption is evident on public NuGet, where Avalonia packages have recorded more than 87 million downloads to date.

Development momentum is accelerating. Version 11.3.0 introduced media-query support for responsive layouts, while ongoing performance optimisations show significant frame rate improvements on Android, with some scenarios seeing more than 2x better performance. Avalonia v12 remains on track for Q4, making our release cadence aligned with .NET.

Avalonia’s drawn UI approach, single XAML dialect and first-class Linux support set it apart from .NET MAUI, genuinely giving developers choice without leaving the .NET ecosystem. The same technology powers Avalonia XPF, our cross-platform fork of WPF, enabling existing WPF applications to run natively on macOS and Linux.

Engineering leaders weighing cross-platform options can install the Avalonia .NET templates today and build a high-performance, visually consistent application for Windows, macOS, Linux, iOS, Android and WebAssembly. Contributors and commentators are invited to inspect the GitHub project and help steer the sponsorship budget toward the issues that matter most.

From a personal experiment twelve years ago to a community-led toolkit relied upon by teams worldwide, Avalonia enters its next chapter with stable backing, an open licence and a clear mandate to become the definitive UI platform for .NET.
