Caveman Code

Not yet independently verified. Dated from the Y Combinator launch post of 13 November 2026; the maker's site was last updated on 12 November and gives no launch date. The cost comparisons with Codex and Claude Code are the maker's own benchmark runs, and the site names no city or country. We will update this when it can be confirmed, and remove this note.

Developers who keep three coding agents open in three terminals are the audience for Caveman Code. The app, from the Y Combinator-backed Caveman Labs, puts Claude Agent, Codex, Cursor and the company's own Caveman agent in one window, in tabs and splits, and adds a supervising agent it calls the Chief, which starts chats, answers their questions, reports back and carries on by itself when the developer does not reply in time.

Built around review

Before a pull request, the app writes a guide with a one-line summary, the decision the developer has to make, and each change set out as before, after and why. Every chat gets its own worktree, agents can message each other and share memory, and plugins from Claude Code, Codex and Cursor work inside it. In beta, agents can drive a Linux desktop and browser on cloud computers and keep working while the Mac's lid is closed. A terminal version is listed as coming soon.

Open-source parts and the cloud

The desktop app is proprietary. The Caveman command-line tool, which wraps Claude Code, Codex and Gemini CLI on the developer's own machine, is open source under Apache-2.0, as are the agent, SDK and skill; a memory package, cavemem, is MIT. Caveman Cloud runs and monitors agents, with spend, keys, policies and traces: free for one person with monthly allowances, $300 a month for a team with $300 of usage included after a seven-day trial, and an enterprise edition that installs in a customer's own AWS or GCP account with a Helm chart.

Credits rather than seats

The app is free when it runs on a user's own subscriptions and API keys. Paid plans buy monthly credits spent at each model's list price: Pro at $20 or $60, and Max at $100 (with $105 of credit) or $200 (with $220), with yearly billing 20% cheaper. A credit goes three times as far on GLM-5.3 and twice as far on DeepSeek Flash and GLM-5.3 Flash. No week, and no five-hour window, may use more than 35% of a month's credits, and top-ups of $5 to $500 last a year.
