Pre-Launch Checklist
Before going live, test your app end-to-end yourself. No prompt can replace actually clicking through your app as a real user would.
Manual Testing Checklist
Run through these flows yourself:
- Build passes — Run
npm run buildlocally, fix any errors (or use prompt, see below) - Sign up — Create a new account, receive magic link, land on dashboard
- Sign out / Sign in — Log out, log back in, verify session works
- Checkout — Subscribe to a plan (use your 100% off test coupon)
- Webhook — After checkout, verify subscription appears in database
- Settings — Check subscription shows correctly, test "Manage Subscription" portal
- Cancel — Cancel subscription from portal, verify status updates
- Protected routes — Try accessing
/dashboardlogged out (should redirect) - Email — Trigger any transactional emails, verify they arrive
Tips for Faster Testing
- Use a fresh browser profile or private browsing — Avoids cached sessions confusing things
- Keep Supabase dashboard open — Watch the
usersandsubscriptionstables update in real-time - Keep Stripe dashboard open — Check webhook logs under Developers → Webhooks → Select endpoint → Recent deliveries
- Test on mobile — Resize browser or use actual phone to catch responsive issues
Verification Prompts
These prompts can help catch things you might miss. Use them as a supplement to manual testing, not a replacement.
Build & Code Check
Run a pre-deploy check:
1. Run npm run build and fix any errors
2. Run npm run lint and fix any issues
3. Flag any TODO comments that need addressing
Report what needs fixing.Database Audit
Use Supabase MCP to audit my database:
1. Check users and subscriptions tables exist with RLS enabled
2. Verify policies restrict users to their own data
3. Verify the on_auth_user_created trigger exists
Report any issues.Placeholder Content Search
Search for placeholder content I might have missed:
1. Look for "TODO", "FIXME", "placeholder", "example.com", "your-"
2. Check app/privacy/page.tsx and app/terms/page.tsx are customized
3. Check meta tags in app/layout.tsx
4. Look for Lorem ipsum or dummy text
List everything that needs updating.Security Check
Run a quick security audit:
1. Search for hardcoded API keys or secrets
2. Check no secrets use NEXT_PUBLIC_ prefix
3. Verify protected routes check auth server-side
4. Use Supabase MCP to verify RLS is enabled
Flag any concerns.Troubleshooting
Deploy Failed
My deployment to [Render/Vercel] failed.
Error: [PASTE ERROR FROM LOGS]
Help me understand and fix this.Works Locally, Broken in Production
My app works locally but [DESCRIBE ISSUE] in production.
Check for hardcoded localhost URLs and list all env vars the code expects.
I'll verify the env vars are set in my hosting platform myself.
