This anonymized report shows the level of specificity a founder should expect from a production readiness review: evidence, severity, fix path, and what must be checked before real customer data enters the app.
A production readiness review for a Lovable-built B2B SaaS app returns specific findings rated by severity, each with the evidence behind it and a recommended fix. This sample covers Supabase access, admin route protection, Stripe handling, security headers, migrations, and observability.
The deliverable ends with an ordered remediation plan that removes launch blockers first. The goal is the shortest safe path from working demo to production, not a rewrite. See the focused Lovable app security review and Supabase RLS review for the issues that dominate these reports.
The app looked demo-ready but not production-ready. The core workflow rendered, but customer data, billing, and admin surfaces needed hardening before launch.
Safe to share privately with test users. Not safe for paid customers or production customer data.
Client-side access patterns made it unclear whether tenants could read or mutate data outside their account.
Rotate keys, lock route auth, prove RLS policies with tests, and move payment-sensitive actions behind server code.
Specific issues, severity, evidence, and recommended fixes from the sample review.
Evidence: Public JavaScript referenced Supabase project config and performed direct table reads from the browser.
Fix: Confirm no service-role key is present, rotate all keys, enforce RLS on every table, and add tenant-isolation tests for anonymous, authenticated, and cross-account users.
Evidence: /admin returned a 200 response and loaded dashboard chrome before redirecting on some client states.
Fix: Move auth and role checks into server middleware or route loaders. Never rely on hidden links or client-side redirects for admin protection.
Evidence: Checkout state was assembled in browser code and did not show a server-side price or tenant verification step.
Fix: Create checkout sessions server-side, verify tenant ownership before session creation, and validate webhook events before changing account state.
Evidence: The production domain did not return Content-Security-Policy, HSTS, or Referrer-Policy headers.
Fix: Add hosting-level headers, start with report-only CSP if needed, and verify third-party scripts before enforcement.
Evidence: Schema changes were applied manually in Supabase with no migration history in the repo.
Fix: Move schema changes into migrations, require review before production changes, and document rollback for destructive operations.
Evidence: Failed API calls appeared in the browser console, but no error tracking or alerting target was configured.
Fix: Add error monitoring, uptime checks, and a lightweight incident checklist before launching paid users.
The goal is not a rewrite. The goal is to remove launch blockers in the smallest safe order.
The useful deliverable is not a generic score. It is the shortest concrete path from working demo to production-safe app.
