terms

Short, because there is little to agree to.

ccx is a program you run on your own computer. No account, no server of ours in the path, nothing to cancel. That leaves five things worth saying plainly.

The licence

ccx is released under the MIT licence. The full text ships as LICENSE in the repository and that text governs. Read it, fork it, sell what you build with it, keep the copyright notice on it.

No warranty

The MIT licence disclaims every warranty, and here that is not boilerplate: ccx runs coding agents that edit files in your working tree. They will sometimes be wrong. The review loop exists to catch that and it does not catch everything.

Run it on a clean git tree, read the diff before you commit it, and do not point it at anything you cannot roll back. If it breaks your code, eats your afternoon or ships a bug to production, that is on you. Same deal as every other tool you run locally.

The two agents are not ours

ccx resells no inference and holds no API key. It launches the official claude and codex CLIs that you installed and signed in to, using your own subscriptions. Anthropic's terms and OpenAI's terms govern your use of their products, including what you may send them and what they may do with it. Nothing here changes those, and if either subscription lapses ccx has nothing to drive.

This project is not affiliated with, endorsed by or connected to Anthropic or OpenAI. "Claude" and "Codex" are their marks, used here to name the two programs ccx drives.

Money

There is no paid tier today. No card on file, no subscription, nothing to buy. Everything ccx does on your machine is free and stays free — the reasoning for that is on the pricing page, along with the test a hosted feature has to pass before it gets built at all.

The hosted tier, which is not live

Written in advance so the deal is public before the thing exists. None of it applies to anyone yet, because none of it is running.

• $5 a month or $48 a year, per seat, cancellable at any time. Cancelling stops the next charge and leaves the current period running to its end.
• Nothing is taken out of the free tier to build it. If a feature would make ccx a better reviewer, it belongs in the free tier and it stays there.
• Your shared runs stay yours. One command deletes any of them, and a delete never requires an active subscription.
• If a vendor CLI change breaks ccx, subscriptions pause automatically and are refunded on request. The product depends on two command-line tools we do not control, and that risk is ours, not yours.
• Do not upload what is not yours to upload. The redactor runs before every send and shows you what it caught, but it is a safety net under your judgement, not a substitute for it. A shared run is a page anyone with the link can read.
• Terms for the paid tier would be finished and posted here before it went on sale, not after. The paragraph above is the intent, not the contract.

Changes

If these terms change, the date below changes with them. Keep using ccx after that and you are working under the new version. The old one is in the repository's git history if you want to diff it.

These are drafts. They were written by the person who wrote the code, to be accurate rather than to be safe, and no lawyer has read them. They name no governing jurisdiction, which a reviewed version would. If you need that settled before you can use ccx at work, say so and I will get it done.
