Uno Space is a constellation of 17 local‑first workspaces — vector design, word processing, spreadsheets, PDF, photo, video, CAD, PLC engineering, Git and more. Each one is real compiled C# running on Uno Platform WebAssembly, built from 145 reusable libraries you can embed in your own apps.

The constellation
Seventeen workspaces. One C# codebase each.
Every app below is the real compiled application — not a mockup, WebView wrapper or embedded third‑party editor. Open any of them to explore features, packages, architecture and a live playground.

One stack
Write once in C#.
Ship everywhere.
Each workspace is a single Uno Platform project rendered through SkiaSharp. The exact same controls, engines and editors run as WebAssembly in the browser and natively on Windows, macOS and Linux — pixel‑consistent, with no JavaScript UI framework in between.

Layered like a planetary system
The apps share a disciplined, dependency‑ordered pattern: UI‑free engines at the core, Skia rendering in the middle, Uno controls and embeddable workbenches on top. Every layer is a package you can reuse on its own.
