Free agentic coding is live

Plan, code, and ship with agents — 100 Atoms a day, $0 forever.

RareMatter is open: a Web Agent, coding chat, CLI, cloud deploys, desktop app, and browser extension — every one of them free.

Paid coding tools charge $120 to $1,200 a year for the plan-edit-run loop. We built the same loop on open models and gave it away: 100 Atoms refill daily, no card, no trial. A build costs 3 Atoms, which works out to roughly thirty builds a day, forever.

Everything shares one account and one Atom wallet. Start in the browser, continue in the terminal, deploy to a live URL, and put the boring parts on Autopilot. If you outgrow the free tier, Pro ($12 for 30 days) adds frontier models and 1,000 Atoms a day — and never touches what free users get.
