For products and AI PM tools

Coding is an API call. Send a change, get a PR back.

Your product knows what it wants built. Send that change to our API. We run it in a sandbox, run your checks, and open a pull request in your repo. You review and merge. There is no agent loop to build.

One request in. A pull request out.

Send the change with your API key. Then poll the run until the pull request link is set.

A pull request in your repo, with a signed record of what ran.

Pricing

API access comes with every paid plan and uses that plan's capacity. Runs draw on your own Claude Max or ChatGPT plan, or on your credits. No per-run fee.
