Own every revision
Private source history from the first Build, plus optional GitHub two-way sync on one selected branch. Full commercial rights.
Build checks before delivery
Every Build must pass TypeScript and a production Vite build. Mythos also attempts bounded desktop and mobile render diagnostics before delivery.
Your backend, your data
Your backend runs in your own Supabase organization. You own the project and data, with provider billing under your control.
Questions about credits
How can I start for free?
Every new account receives 5 credits after account confirmation—enough for one new Build and one AI edit, or five Plan responses. No card is required.
What does a credit pay for?
A completed Plan response uses 1 credit. A new Build uses 3, an AI edit uses 2, and a Template Remix uses 5. If a Plan response fails before it is saved, its credit is returned.
What requires a balance of 10 credits?
Project ZIP downloads, new GitHub connections, member invitations, and new custom domains are available while the workspace billing owner has at least 10 available credits. These credits are not reserved or charged for access. There is no subscription.
What happens below 10 credits?
Project ZIP downloads and new GitHub connections, invitations, and custom domains pause until the workspace balance reaches 10 again. Existing GitHub sync, connected domains, and accepted members keep working. Your code, editor, Preview, and Mythos publishing remain available; AI work uses its normal credit price. An invitation accepted after the balance drops waits for a top-up.
Do credits expire?
No. Top-up credits stay in your balance until you use them. There is no monthly renewal.
Can I connect GitHub and Supabase?
With 10+ workspace credits, connect a private GitHub repository with two-way sync on one selected branch. Your existing sync continues below that balance. For a managed backend, authorize your own Supabase organization; your application data and provider billing stay under your control.
Who owns the generated code?
You do. Mythos keeps private source history while you build. You receive full commercial rights with no attribution requirement, and you can modify or deploy the code anywhere.
