Omux

omux

A 5 MB native Mac terminal for running fleets of coding agents.

Written in Swift on SwiftTerm, no Electron, no web view, launches instantly. omux keeps many Claude Code and Codex sessions in one window, shows you which one needs you, lets you answer from the sidebar, and gives each session its own branch.

Eight seconds of the 37-second tour, or the 23-second version.

Why omux

Running one agent is easy. Running eight is a tab-switching job: you poll each terminal to see whether it's waiting on you, and you lose a conversation every time a window closes.

omux turns that into a dashboard.

- One sidebar for every agent. Projects hold sessions. Each session shows whether its agent is working, needs you, or is done. The Dock badge counts the ones waiting.
- Answer without switching. Claude Code permissions and Codex approvals have Allow and Deny buttons right on the session. A notification takes you to the session that needs you.
- Nothing gets lost. Every session keeps its exact conversation across restarts and relaunches.
- Parallel work that stays apart. A worktree session gets its own branch and folder. The pull request's checks and reviews appear next to it, and failing checks go to the agent in one click.
- Review before you merge. Read the diff, leave notes on lines, send them to the agent as one message.
- Native and small. SwiftUI and SwiftTerm, a 5 MB download, no telemetry.

Features
