Built for agentic work

-Real Chromium: Chrome-quality tabs, rendering, extensions, and omnibox behavior
-Task-shaped workspaces: organize web tabs and tools around the task instead of one endless tab strip
-Terminal surfaces: keep shells and browser tabs in the same window and compositor
-Free and open source: inspect the code, file issues, and build from source on GitHub

Install

Run the per-user installer once. It installs under ~/.local without root and enables signed in-app updates. Choose the Debian package instead if you want updates managed by your package manager.

chmod +x cmux-linux-x64-installer.run
./cmux-linux-x64-installer.run
