Quarters
Gives every coding-agent project its own tab, running agents and dev servers side by side.
Quarters replaces the open-five-terminals-and-remember-which-one-finished routine with one app: each project gets a tab, you switch between them with a click, and each can run its own coding agent, Claude Code by default or Codex, Gemini CLI, Aider and others, plus the dev servers it needs. It has no AI, accounts or cloud of its own, so your logins and machine stay yours, and it flags which project is waiting for you, longest wait first. It's free, open source under MIT, and runs on macOS or a Linux server, with remote access from a phone or iPad.
What holds up
- +Free and open source under MIT — no account or cloud service, everything runs on your own machine.
- +Runs multiple coding agents across projects at once and flags which one is waiting for you, longest first.
- +Automations start your whole dev stack in one action instead of several terminal tabs.
- +Never overwrites a message you've started typing, even when the agent's queue delivers the next prompt.
Mind the limits
- −No AI, accounts or cloud of its own — you still need your own coding-agent subscriptions to do anything.
- −macOS or Linux server only — no native Windows build.
