AI app builders
Build a client check-in or booking web app from a written spec, with Supabase wired in.

Free tier with daily credits; paid plans for more.
lovable.dev ↗AI app builders
Prototype a full-stack app in the browser and deploy it in one click.

Free tier; paid plans by token usage.
bolt.new ↗AI app builders
Its Agent builds, runs and hosts the app in one place, database included.
verdict › Good all-in-one if you never want to think about hosting. Watch usage costs.
