Terminal workspaces for Linux, Windows & macOS

Group your terminals into named workspaces, split them into as many resizable panels as you need, and get a desktop notification the moment your AI CLI finishes a long-running task.

umux — workspaces, tabs and resizable panels — umux main window — workspaces, tabs and panels

Workspaces & panels

One workspace per project, tabs inside it, and any tab splits into as many resizable panels as you need — with a minimum size enforced so nothing collapses. Workspaces persist across restarts and can be pinned to stay on top.

Agent status & notifications

umux reads the standard OSC completion signals emitted by AI CLIs (Claude Code, Codex, Gemini CLI, Aider…) and fires a native desktop notification when a long-running task finishes. Each panel shows a live agent status — working, needs-attention, idle — detected from escape sequences and process names, never from your terminal content.

Restored umux session with workspaces and panels

Session restore

Close the app, come back tomorrow: your workspaces, tabs and panel layouts are restored exactly as you left them.

First run — unsigned builds

umux is free & open source and ships without a paid code-signing certificate, so your system may ask for confirmation once:

macOS: right-click the app → Open, or System Settings → Privacy & Security → Open Anyway.
Windows: on the SmartScreen prompt choose More info → Run anyway.
Linux: AppImage needs chmod +x once; .deb/.rpm install normally.
