Build apps with AI, in your own Cloudflare account
Tell chef what you want. It plans the work, builds every feature in its own sandbox with a live preview, and ships it once the checks pass. Sign in with Cloudflare and start building; your code, keys and previews stay in your account.
chef is free and open source. It runs on a Cloudflare account with the Workers Paid plan.
What chef takes off your plate
You describe the outcome. chef handles the busywork that usually comes with building software.
Sessions run themselves
Each request becomes a session that chef starts, tracks, keeps up to date and closes for you. Run many at once and none blocks another.
No git chores
No branches, merges, rebases or conflicts to handle. chef keeps every session in sync with main and merges finished work for you.
A preview for everything
Every change builds in its own isolated sandbox with a live link. Previews sleep when idle and wake on the next click.
Checked before it ships
Tests, typecheck and an AI review must pass before anything reaches main.
Your keys stay yours
Bring an Anthropic API key or any compatible provider. Keys stay in your Cloudflare account, never in the browser or the sandbox.
GitHub when you want it
Projects live with chef in your Cloudflare account. Connect GitHub only if you want a repository kept in sync.
Set up in a few clicks
No terminal, no Docker and nothing to install. chef sets up its engine in your Cloudflare account, and you use it right here.
Sign in with Cloudflare
Cloudflare shows exactly what chef asks for, and you pick the account it can use.

Questions
Where do my code and data live?
In your Cloudflare account. Projects are git repositories in Cloudflare Artifacts, and your model keys, settings and previews stay with your chef engine there. GitHub sync is optional.
What does this site keep?
Your Cloudflare user id and email, when you joined and last signed in, and where your chef engine runs with the key this site uses to reach it. Nothing else.
Does chef keep access to my Cloudflare account?
No. The access you grant at sign-in is used only while chef sets up or updates its engine, and it is revoked right after. You can review or remove apps any time in Cloudflare under My Profile, Access Management.
What does setup create in my account?
A Worker named chef with its Durable Objects, a container image for its sandboxes, a Vectorize index for project memory, an Artifacts namespace for your repositories, and one API token limited to Workers scripts so chef can publish previews. Everything is yours to inspect or remove.
Which Cloudflare plan do I need?
Workers Paid, because chef uses Containers and Artifacts. If your account is on the free plan, the setup page links you to the upgrade.
