Lovable App Launch Checklist: 7 Checks Before Real Users

A working preview answers one question: can you complete the happy path in your current test setup? A launch asks harder questions. Can one user see another user's records? Can a browser reach an admin credential? What happens when a payment confirmation arrives twice, or a deployment goes wrong?

You do not need to turn a small MVP into an enterprise programme. You do need to know what could expose customer data, lose money or leave you unable to recover. Use this checklist before inviting real users or accepting real payments.

1. Confirm who owns every production dependency

Make a short ownership sheet for the Lovable project, connected Git repository, domain and DNS, database and storage, payment and email providers, and monitoring. Record an owner and recovery route for each. Use named accounts, enable multi-factor authentication where available, and remove collaborators who no longer need access.

Owner check: open each service in a private browser window and prove that the documented recovery method belongs to the company, not a contractor's personal account.

2. Test data access as different users, not just as yourself

If the app uses Supabase, inspect every table exposed through its Data API. Exposed tables need Row Level Security (RLS); grants control which operations a role may attempt, while policies control which rows the operation may reach. A policy that looks plausible is not the same as a tested boundary.

Test reads and writes separately. Cover files as well as database rows if the product uses uploads. Keep service-role or secret keys on a trusted server because those credentials bypass RLS and must not be exposed in the browser. Use two fresh test accounts and a signed-out session; never test another company's app or data without written permission.

3. Separate public configuration from secrets

Search the built frontend, repository history and browser network requests for credentials. A publishable client key can be intentionally public when the provider's permission model is configured correctly; an administrator, service-role or webhook secret cannot. For each credential, record where it is stored, whether browser code can read it, what it can do, who can rotate it and what breaks during rotation.

Owner check: rotate any credential that has appeared in public code or logs. Do not copy live secrets into a checklist, ticket or AI prompt.

4. Treat the server as the authority for paid or privileged actions

Do not grant access because the browser reached a success screen or sent a field such as paid: true. Confirm payment and entitlement changes on the server using the payment provider's trusted event flow. For Stripe, register an HTTPS webhook endpoint, verify incoming events, and make processing safe when an event is delivered more than once.

• ▸Test successful payment.
• ▸Test failed or abandoned payment.
• ▸Test delayed confirmation and duplicate event delivery.
• ▸Test refund or cancellation if the product supports it.

5. Define recovery for the database and uploaded files

Backups enabled is not yet a recovery plan. Write down how much data you could lose, who can start a restore, how long the app may be unavailable and how you will validate the restored result. Check each data store independently: Supabase database backups contain Storage metadata, not the stored objects themselves, and backup options vary by plan.

Owner check: confirm the latest available restore point and separately inventory uploaded files. Rehearse a restore into a safe non-production environment when your tooling permits it; never experiment with the only production copy.

6. Prepare a release and rollback card

• ▸Record the exact code revision being released.
• ▸List database migrations and configuration changes.
• ▸Name the person watching errors and critical journeys.
• ▸Set the threshold for stopping or rolling back.
• ▸Write rollback steps for code, schema and configuration.

Lovable separates editing from publishing, so publication is an explicit release boundary. Application data migrations and third-party configuration may still need their own rollback steps. Avoid combining a risky data migration, payment change and public announcement in one irreversible release.

7. Run one launch rehearsal from the user's side

1. Sign up and sign in with a fresh account.
2. Create, edit and delete the product's core record.
3. Upload and retrieve a file, if applicable.
4. Pay and receive the correct entitlement, if applicable.
5. Receive essential transactional email.
6. Sign out, reset access and delete the test data.

Watch server logs and error reporting during the rehearsal. Record the owner of each failure and repeat the failed journey after the fix. A checklist is evidence only when the expected and actual results are written down.

A compact go/no-go record

For each section, record pass, fail or not applicable, the evidence link, owner and date. Do not convert an unknown into a pass. A limited review reduces avoidable risk; it cannot guarantee that an app has no vulnerabilities or future failures.

To see how evidence, severity, fix order and retest steps can fit into one bounded deliverable, read the fictional sample MVP security review report. It demonstrates the report format; it is not a client result or a security guarantee.

If the app is stuck before launch, Plixy's Lovable app rescue service starts with the current code and a keep-versus-rebuild assessment. If it is working and you want an independent look at permissions, secrets and critical flows, request the free MVP security review. The review is scoped feedback, not a certification or exhaustive penetration test.
