Lunchbox is a completely free AI workspace for Mac, Windows and Linux, and its built in prompt caching saves you up to 90% on tokens. Bring the agents you already pay for, like Claude Code, Codex, Grok and Gemini, plus local models and API keys from 16 providers, and they work on your project as one crew with one shared memory. When one runs out of usage, the next picks up the same task with a briefing, so nothing stops and no context is lost. They also pass work to each other mid task, so Claude can ask Codex to draw an image and keep going. No account and no paid tier. You still pay for any agent plans or API keys you use, and the Mac build is not yet signed.
Claude Code kept hitting its limit mid task and I was explaining everything to Codex again from scratch. Now they share one room and one memory, and the next agent just carries on.
