Lovable + Supabase launch security: a 10-minute proof workflow

Lovable can take an app from prompt to public URL in a weekend. Supabase can add authentication, data, storage, and functions almost as quickly. The speed is real; so is the gap between ‘the page works’ and ‘the deployed boundary was checked.’

This workflow closes that gap in ten minutes without asking you to create a VibeAudit account or upload source code. It combines five manual checks inside the systems you control with one passive check of the public origin you are authorized to test.

This is VibeAudit-owned guidance, not a customer result. A public-surface scan cannot prove private database policies, authenticated authorization, source-code safety, or every vulnerability. Unsupported areas remain Security Unverified.

Minute 0–2: fix the scope before testing

Choose the exact public origin you own or have written permission to assess. Confirm that production—not a preview or localhost build—is the target. Keep active probes off unless you separately understand and authorize them; VibeAudit's no-account form defaults to passive, browser-observed checks.

Write down what the check cannot see: Supabase dashboard settings, private Edge Functions, authenticated user-to-user boundaries, private dependencies, and business logic. Those are manual or deeper-test tasks, not implied passes.

Minute 2–4: check Supabase RLS and key roles

The Supabase anon key is public by design. The controls that matter are Row Level Security and whether privileged service-role credentials stayed server-side.

For every user-data table, enable RLS and test both an allowed user and a denied user. Search the deployed browser bundle for service-role markers and secret-shaped server keys. If a privileged key reached the browser, rotate it and move the operation behind server-side authorization.

VibeAudit may detect observable key-role or access signals on the deployed surface. It does not replace direct RLS policy tests in your Supabase project.

Minute 4–6: test storage and authenticated routes

Open a private upload URL in a clean incognito session. If it loads without a signed URL or authorized session, the bucket or object policy needs attention.

Then copy one data-bearing request from the authenticated app and replay it without credentials. A polished login wall is not an authorization control if the underlying route still returns another user's data.

Do not test another person's account or data. Use owned test users and inert records.

Minute 6–8: verify Stripe grants access server-side

In Stripe test mode, complete the intended purchase flow with DevTools open. Access should be granted only after the server verifies the Checkout Session, PaymentIntent, or signed webhook event. A browser redirect or client-side paid flag is not payment proof.

Also test the negative path: an abandoned or failed payment must not unlock the product. Keep test-mode activity separate from real customer claims.

Minute 8–10: run the no-account public-surface check

Run VibeAudit's free Thorough Scan on the exact owned origin. Read the checked scope before the grade. Review severity counts, categories, the observed-scope summary, and explicit claim limits. No source upload, card, or VibeAudit account is required for the free result.

A clean result is Clear in Verified Scope—not ‘secure,’ ‘vulnerability-free,’ or a penetration test. Pair it with the manual RLS, storage, authorization, and Stripe checks above.

What the paid layers add

The free scan gives the scoped diagnosis. US$9 Reveal adds exact finding locations and the full severity/evidence summary. The US$29 Launch Pass adds copy-paste fix prompts for your own coding agent, Markdown/HTML evidence exports, and a signed Launch Security Pass that others can independently verify.

Paying expands the delivered evidence and artifacts; it does not expand the scanner's claim beyond what was actually checked.
