The 10-point launch checklist for AI-built and no-code apps

updated 2026.09.21 · vardha solutions

These are the ten issues we find most often when founders ask us to look at an app built with Bubble, FlutterFlow, Lovable, Bolt or Cursor. None of them show up in a demo. All of them show up eventually — usually the week you get your first real traffic.

1. Other users' data is one request away

If your database relies on the app's screens to hide data, anyone with a browser's developer tools can often read it anyway. Check: sign in as a test user and try to load another user's record by changing an ID in the URL or request. Fix: enforce access in the database itself — Bubble privacy rules, Firebase Security Rules or Supabase row-level security.

2. A secret key ships to the browser

Publishable keys are fine in the client. Secret keys for Stripe, OpenAI or your database admin account are not. Check: search your front-end code and your browser's network tab for keys starting with sk_ or labelled "service role". Fix: move the call to a server, edge function or private API call, and rotate the exposed key.

3. Nothing stops a runaway bill

An endpoint that calls a paid AI or email API with no limit per user can cost thousands overnight. Fix: add per-user rate limits and set spending caps with your providers.

4. The app freezes when a third party does

When OpenAI, Stripe or your email provider is slow or down, does the user see a helpful message — or a spinner forever? Fix: timeouts, clear error states and retries that can't double-charge.

5. Queries that work for ten users, not five hundred

Loading every record and filtering on the page feels instant in testing and grinds to a halt with real data. Fix: filter and paginate on the server, and index the fields you search on.

6. "Delete account" doesn't delete anything

App stores and privacy laws expect deletion to actually remove a user's data, including files and third-party records. Check: delete a test account and look for what remains.

7. No one is watching after launch

Without error monitoring and uptime checks, your users find bugs before you do. Fix: add Sentry, Crashlytics or similar, and an uptime alert that reaches a phone.

8. No tested way back

Backups you've never restored are a hope, not a plan. Check: restore last night's backup somewhere safe and confirm it works.

9. Email that lands in spam

Password resets and receipts sent from an unauthenticated domain often never arrive. Fix: set up SPF, DKIM and DMARC for your sending domain.

10. Store and legal basics missing

Privacy policy, terms, account deletion, permission explanations and accurate privacy labels are the most common reasons mobile apps are rejected. Check them before you submit, not after.

If you can confidently tick all ten, you're ahead of most apps we see. If you can't, that's exactly what our Tech Architecture Audit is for.
