Why Developers Choose Mythetech

Ship in C#

Build desktop apps with Blazor and Razor — no context switching to XAML, Electron, or native UI toolkits.

Native Performance

Platform WebViews instead of bundled Chromium. Smaller binaries, lower memory, AOT-compiled.

Web-Grade DX

Hot reload, live preview, and the full Blazor component ecosystem — desktop development that feels like web development.

Open Source First

Most of our tools are free and open source. We believe in building in the open, contributing to the .NET ecosystem, and giving developers the freedom to inspect, extend, and contribute to the tools they use.
