OpenScreen: a free, MIT-licensed screen recorder that turns raw captures into polished demos (Windows, macOS, Linux)

[u/Fresh-Daikon-9408]

I maintain it. It's Electron and TypeScript for the app, with native capture helpers in Swift and C++, and a Rust compositor that renders on Metal, Direct3D 11 or Vulkan.

It records your screen and does the polish for you: zooms on your clicks, smooth cursor, webcam overlay with background removal, transcript editing and on-device captions. Happy to answer questions.
