Create an account firstWhat a build costs
| Size | Typical pair | Credits |
|---|---|---|
| Small | Two small utilities or CLIs | ~225 |
| Medium | A desktop or mobile app pair | ~1,150 |
| Large | Two large, feature-rich programs | ~3,600 |
Credits are reserved when a build starts, and you're charged for actual use. A build can never spend more than you hold.
Billing questions
Why credits instead of a flat price per build?
Builds vary a lot. Two small utilities cost a fraction of two large apps. Credits mean you pay for the work that actually runs, not a worst-case price.
Can I cancel?
Yes, any time, from the billing portal on your account page. Credits already on your account stay there.
What happens if I run out mid-build?
That can't happen. The build's spending limit is set from your balance before it starts, and it stops cleanly at that limit.
Do referrals earn credits?
Yes. When a friend you invited makes their first payment, you get 500 credits. How referrals work.
