Avalonia Enterprise
The complete commercial platform for building on Avalonia
Not a support contract — the complete commercial offering for organisations building serious software. It brings productivity, support, maintainability, security and deployment flexibility together so you can build, ship and maintain with confidence.

Premium controls and tooling out of the box mean less UI to build and a faster path to shipping.
Reduce engineering effort
Stop building and maintaining complex UI components and infrastructure in-house.
Minimise delivery risk
Engineering-led support and response-time SLAs keep your team unblocked and on schedule.
Deploy in secure environments
Offline, air-gapped deployment with no cloud services or licence-server dependencies.
Maintain for the long term
Long-Term Support releases with security updates and critical maintenance fixes.
Work with the team behind Avalonia

What you get
Everything you need to build, ship and maintain with confidence
Avalonia Enterprise is organised around what every serious software team needs — from premium tooling and controls through to long-term maintenance.
Tools
A complete, professional toolchain
Avalonia Enterprise includes the full developer toolchain — IDE extensions, runtime inspection and one-click packaging — so your team builds, debugs and ships faster across every platform you target.
Outcome — Reduce development time and engineering cost.
Components
Premium controls, with full source code
