What is it?

Wu is a native code editor written in Rust, designed to open quickly and stay responsive on large projects. It runs without Electron or webviews, and its memory footprint is described as lower than VS Code and Zed.

Wu is a fork of Zed and diverges significantly from it. It ships with built-in support for coding agents including Claude Code, Codex, and OpenCode, so developers can work with these agents inside the editor. It requires no account sign-in and does not send usage data or telemetry.

Prebuilt installers are available for macOS (Apple Silicon and Intel), Windows x86-64, and Linux (x86-64 and AArch64), with a shell install script for macOS and Linux. The project is licensed under GPL-3.0-or-later with some Apache-2.0 components.

Key features

  • 01Native implementation with no Electron or webview dependency.
  • 02Built-in support for Claude Code, Codex, and OpenCode coding agents.
  • 03No account sign-in and no telemetry.
  • 04Installers for macOS, Windows, and Linux.

Use cases

  • Working with coding agents directly inside a lightweight editor.
  • Editing large codebases on a machine where memory use matters.
  • Trying a Zed-based editor without account or telemetry requirements.

Quick start

  1. 1

    Run the official install script from the README (macOS and Linux)

  2. 2

    Download the Windows installer from the releases page

  3. 3

    Or download the manual build for your platform from the releases page

Things to know

  • Builds on the Zed development setup, which is not a simple build process.
  • Licensed under GPL-3.0-or-later with Apache-2.0 components, which is copyleft.
  • Forked from Zed and diverges heavily from it, so it may drift from upstream.
