Pay for what gets built. Nothing else.

No. Sign up with GitHub or your email address and you are on Free, with $3 of AI usage every month. You only add a card if you choose a paid plan or a top-up.

Build and try your first apps from start to finish. Free includes $3 of AI usage a month, which is enough for two or three small apps, up to 3 projects at a time, and 1 published app on a crisp address. To use the free usage, sign in with GitHub or confirm your email address. This keeps the free plan fair for everyone. Your own domain, coming soon, will need a paid plan. If you run out before the month ends, a $10 top-up adds $9 of usage without a subscription.

Because usage is charged at exactly what the AI models cost us, with nothing added. The rest of the price pays for everything else: keeping your published apps online, storing your projects and versions, and card fees. So $15 of crisp usage goes further than $15 of credits that have a markup built in. A typical new app costs about $1 to build and check.

Add your Anthropic API key on the Billing page. Your requests then run on your key, and Anthropic bills you for them directly; crisp adds nothing. Building and hosting your apps are free up to 250 CPU hours, 500 GB hours of memory and 25 GB of storage each month (a fifth of that in your first 30 days). Most people with a few small apps never reach it. Paying for more is coming soon; until then, new requests wait for the next month once it is used up, and published apps stay online.

Soon, from your own Claude Code: you will sign in to Claude Code on your computer with your subscription and connect it to crisp. Until then, use an Anthropic API key. crisp never asks for your Claude subscription login or token. Anthropic allows subscription sign-in only through its own apps and does not allow other products to collect or store subscription tokens, so pasting one into any website could put your Anthropic account at risk.

crisp checks your key with Anthropic, then stores it encrypted. After that, only its last four characters are ever shown, even to you. Your key is used only to run your own requests, at the moment each one starts. It is never written into your app's files or into logs, and it is removed from everything crisp shows you. Remove it at any time and it is deleted at once. You can also turn it off yourself in the Anthropic console. crisp keeps a record of when your key was saved, used and removed, never the key itself. While a request runs, the AI and the commands it runs for your project can use the key, as with any tool that writes code with your key. So give crisp a key of its own with a monthly spending limit.

One US dollar of AI usage, counted at the price the AI models charge us. A request that uses 12 cents of model time costs you 12 cents of your allowance.

You can still open your projects, edit code, browse your data, publish and export. New AI requests wait until your allowance resets, or until you top up. Published apps keep running.

Not for the repair. When crisp breaks something and fixes it in the same request, that work is not charged. A request that ends in an error, or that our platform interrupts, is free. Undoing a request within 10 minutes of it finishing refunds it. If a request still went badly, write to us and a person will look at it and refund usage that did not help you.

No. Your allowance resets on your billing date each month. Top-ups you buy do not expire.

Nothing stops. Limits apply only to starting a new project or publishing another app. Your projects and published apps keep running, and you can delete a project to make room or upgrade at any time.

Yes. You keep your plan until the end of the period you paid for, then move to Free. Your projects, versions and published apps stay.

You do, on every plan. Export the code to GitHub and download your data whenever you like.
