Starter prompt

Paste this into Lovable as your first message. It has not been used in a test build.

Prompt · Lovable58 words
Build a web app connected to my Supabase project: email and password sign-up, a dashboard where users create, edit and delete their own items, Row Level Security so users only see their own rows, a Stripe Checkout button via an edge function, and an email receipt sent with Resend. Store the Stripe and Resend keys as Supabase secrets.

Security check

Results will show here after the test build. Until then, check these yourself before launch.

Gotchas

  • Some Lovable features (in-editor backend views, auth config from chat) only work with Lovable Cloud, not your own Supabase (Lovable docs).
  • Lovable projects that share one Supabase project overwrite each other's secrets (Lovable docs).
