One principle: we charge when we spend money on your behalf — hosting your data, running AI, shipping your code. Building and previewing stay cheap or free. And you're never charged for a build that fails verification.
Whatever plan you're on, the same four promises hold.
You see what each build cost the moment it finishes — never a mystery number at the end of the month.
A build that doesn't pass verification costs you nothing. We don't bill you to fix our own mistakes.
Spending stops the moment your allowance runs out, with a clear prompt — it never keeps running quietly in the background.
Your apps are real code you can take with you. Cancel any time and everything you exported keeps working.
Anything you've exported is yours forever — real code, any editor opens it. Managed Cloud backends pause gracefully with a full data export available. Paid tiers add convenience, never ransom.
Owning and shipping the code is where the real value lands, so it's the paid line. Free still gets a real, persistent backend by connecting your own Supabase — that costs us nothing, so it stays free.
A build spends credits in proportion to the work — a small tweak is a few, a full app is more. Free gives you starter credits to try it; Pro renews 3,000 a month, Studio 12,000, Max 25,000. Previews don't touch credits at all — they run in your browser. And you're never charged for a build that fails verification.
Monthly allowances reset each month; purchased top-ups never expire.
