Why Quarters

If you use a terminal coding agent — Claude Code, Codex, Gemini CLI, Antigravity, OpenCode — on more than one project, you know the routine: a terminal window per project, cd into each one, start the agent, start the backend, start the frontend, then remember which window was waiting for you.

Quarters is a simple, focused home for your coding agents that takes that routine away. Pick the agent you like (Claude Code is the default, and each project can use a different one). Its goals are deliberately narrow:

1. Switch between projects instantly. Every project is one click (or ⌘P) away; its agent sessions keep running in the background while you're elsewhere.
2. Work on several projects at the same time. Agents run in as many projects as you like, and Quarters tells you which one finished and is waiting for you.
3. See what's going on at a glance. A side panel shows git changes, the project's automations and servers, and what the agent tells Quarters: for Claude Code the session's model, context and tokens, your plan's usage, what it edited, and the project's MCP servers and skills; for Antigravity its plan and model quotas.
4. Start the rest of your stack in one go. Automations open the terminals a project needs — backend, frontend, a script, a watcher — each in its own folder, side by side, when you open the project, on a schedule or with one click.
5. Do the daily chores where you work. Commit, push and open pull requests (with CI status), run a project's scripts, stop the dev server holding a port, undo an agent turn that went wrong, search every project at once, and copy a summary of your day.
6. Work from anywhere. Leave Quarters running on your big machine at home and use it from a laptop, tablet or phone through the browser: the same projects, the same live sessions, secured with passkeys.

It is built for developers and their coding agents, and nothing else: no general-purpose terminal features, no AI of its own, no accounts or cloud services. Your projects, your logins and your machine stay yours.

Quarters is an independent open-source project. It is not made by, affiliated with or endorsed by Anthropic, OpenAI, Google, GitHub or the makers of the other agents it runs. Claude and Claude Code are trademarks of Anthropic; the other names are trademarks of their owners.

Features

Home: every project at a glance

The house at the left of the title bar (or Home in ⇧⌘P) shows the home page, with your tabs still running behind it:

• Jump to a project, add one, search conversations, Settings: one tile each, with its shortcut. A different tagline greets you every time.
• Today, across every project: sessions, tokens written and read, and the cache hit rate, with the last two hours as an animated chart (bars rise in, the current five minutes glow; hover one for its time and tokens).
• Today's work: per project, your commits since midnight, the agent conversations you had and how many prompts, and what isn't committed yet. Copy puts it on the clipboard as Markdown, for a standup or a timesheet (also ⇧⌘P → Copy today's summary).
• Active now: every running session, the ones waiting for you first.
