Common questions
Why won’t my emails send?
Corin emails you a six-digit code to sign in and a note when a build finishes. If one doesn’t arrive: check your spam folder, confirm the address is right (use “wrong email?” on the sign-in screen to re-enter it), and give it a minute — there’s a short cooldown before you can resend.
If you’re asking about an app you built with Corin, its emails go through the email provider you connected to that app — check that provider’s dashboard and sending logs.
Why am I getting a 429 error?
A 429 means “too many requests” — something is being rate-limited. Corin builds run against the Anthropic API, which caps how much work can run at once. During busy periods a build can be briefly throttled; Corin retries automatically.
If you keep seeing it: wait a few minutes, and avoid starting several builds at the same time. If it doesn’t clear, email us.
How does billing work?
You’re charged only for work that passes its checks in a real browser — failed attempts cost nothing, and it’s $1.10 per check that verifies. Corin runs on prepaid credit: builds pause when your balance runs out, and nothing is charged past it.
A Pro subscription is $20/month and adds $20 of credit on each renewal. Add credit, add or change your card, view invoices, or cancel from Settings, which opens the Stripe customer portal.
Where does my published app live?
Published apps get a subdomain — for example bloom-salon.corin.build. Each app is a single self-contained page that Corin hosts for you on Cloudflare; there's nothing else to run or maintain.
Connecting a custom domain you already own is on the roadmap.
