eQuantic UI
Write components once in C#. On the web they compile to JavaScript at build time, without WebAssembly. In a native app they render through Photon, eQuantic's own GPU engine on Metal and Vulkan.

WHY IT EXISTS
Three decisions the framework is built on
Written once, in C#One vocabulary of components that every target realises its own way: the DOM and CSS on the web, GPU pixels in a native app. No WebView, no Skia.
Typed styles, no CSS to writeColors, spacing and type are C# values. The web gets deduplicated atomic classes, and a native app paints the same values on the GPU.
Server Actions, type-safeMark a method [ServerAction] and call it from the client. Only marked methods can be reached, and one marked [Authorize] is checked before it runs.

WHY .NET TEAMS PICK ITOne stack, not twoMost .NET shops end up with a JS stack they barely maintain — one team in C#, another in TypeScript, two CI pipelines, two deploy stories. eQuantic.UI collapses that into the stack you already run.
One language, end-to-endThe model, the endpoint and the button that calls it are all C#, reviewed by the same people, in one repository.
Web and native, one codebaseThe same components open in a browser and in a native window, so the desktop and the phone need no second UI stack.
Tooling you already rundotnet watch reloads the page in place, source maps stop the debugger in the C# you wrote, and the build is the dotnet build your CI already runs.
Owned, not rentedMIT licensed, on NuGet and developed in public — and the site you are reading is built with it.
