Wu is a code editor for people who want the speed of a native app and the familiarity of VS Code. The name comes from wu wei: effortless action.
Wu is a fork of Zed. It inherits Zed's editor core, GPU rendering, and language tooling, but strips out the collab and AI features.
- Native and fast. Written in Rust. No Electron or webviews. Opens instantly and stays responsive on large views.
- Lightweight. Wu's memory footprint is lower than VS Code and Zed. See benchmarks.
- No built-in AI features. Bring whichever agent or harness you already use.
- Feels like VS Code out of the box. UI and defaults are tuned so you don't have to relearn your editor.
- No account or telemetry. Nothing to sign in to. Wu never sends your usage data anywhere.
See INSTALL.md for more.
See docs.
On macOS, the Wu extension for Raycast lets you open recent projects, new windows, settings and more straight from Raycast.
Wu builds the same way Zed does. See the Zed development docs.

Wu is a derivative work of Zed and shares the same licenses.
Thanks to the Zed team for building an excellent editor and releasing it as open source. Wu would not exist without their work.
