Offrun is a free app for Apple Silicon and Intel Macs that manages multiple AI coding agents from one workspace. Run Claude Code, Codex, AGY, Grok Build and Muse Code side by side, and see who is working, who needs you, and how much usage each account has left.
Every agent in a project gets its own git worktree, so two agents on the same repo never touch the same files. Pick a second agent as a reviewer and its findings land in the chat while the work is still uncommitted. Nothing merges on its own.
Connect multiple logins per harness. When one hits its usage limit, Offrun moves the chat to a login with room left, or offers another agent that picks up the whole conversation. Project memory keeps repo conventions and each agent's goals and plans. Offrun runs the CLIs on your Mac, signed in as you, with no API key, and prompts go straight to your provider.
