Uno Platform

Open-source cross-platform .NET, accelerated by agents, runtime visual designer, and AI-powered workflows

[Uno Platform @UnoPlatform]

Today we’re shipping the biggest release in our 10-year history.

Uno Platform Studio 3.3: a workbench for you and agents to easily build, validate, and ship cross-platform applications together. Now available as a Windows/macOS/Linux desktop application for development, and an iOS/Android app for testing.

Uno Platform 7.0: 2x faster, 5x smaller, and built for the agentic world.

With AI you can write code fast. What makes a great app, though, is everything underneath - speed, size, platform reach, and behavior you can trust because you were able to easily validate it.
