Treat every frontend value as public
Browser code can be inspected. Move private API keys and privileged operations into Lovable Cloud or Supabase Edge Functions, then rotate anything that was exposed.
Lovable app security checklist
Check the live app, not only the project.
Lovable can review code, dependencies, database rules, and project configuration. LaunchGlint adds a separate GET-only look at what the published URL exposes to a stranger before you share it.
Frontend secrets
Supabase hints
Noindex

Six checks before publishing wider
Preview the deep reportTest Supabase RLS with two users
Enable RLS on sensitive tables and verify that one user cannot read or change another user's records. Recheck new tables after every schema change.
Enforce auth on the server
Frontend route guards are useful for navigation, not authorization. Validate sessions, roles, and permissions inside server-side functions for protected actions.
Scan the exact published URL
Preview and production can differ. Check the live domain for accidental noindex, weak redirects, missing metadata, source map references, and debug leftovers.
Use both security views
Run Lovable's project security checks for code, dependencies, database configuration, and RLS. Use LaunchGlint for the separate public response and buyer-facing surface.
Make payment and support credible
Before charging, show pricing, delivery expectations, support, privacy, terms, and refund language on the same domain buyers are evaluating.
Lovable fix prompt
Give the builder a bounded repair task.
Pre-launch security review prompt
Review this Lovable project for production launch. 1. Find secret or privileged values reachable from frontend code. 2. Move sensitive calls to server-side functions and validate auth there. 3. Review RLS for every sensitive table and design a two-user isolation test. 4. Remove debug artifacts and public source maps not needed in production. 5. Verify indexing, security headers, support, privacy, terms, and refund paths. List the files changed and give exact steps to verify each fix on the published URL.
