Base44 lets you build full-stack apps from prompts, which is genuinely powerful. But when an app breaks in production, the same patterns tend to show up again and again. Here are the six failure modes we see most often, and how we approach fixing each one.

1. AI-agent regression loops

You ask the agent to fix one thing and it quietly breaks three others. The fix is to lock down a known-good state, reproduce the regression in isolation, and make targeted edits instead of re-prompting the whole app.

2. Auth and SSO bypass

Routes that should be protected end up reachable without a session, or role checks live only on the client. The repair is to enforce auth server-side and verify every protected route actually rejects unauthenticated requests.

3. Stripe webhook 500s

Payments succeed but your app never hears about it because the webhook handler throws. Fix the signature verification, make the handler idempotent, and confirm events are acknowledged.

4. Credit burn

Inefficient prompting and runaway loops quietly drain your build credits. The fix is to audit where credits go and tighten the prompts and flows that waste them.

5. SEO invisibility

Client-side-only rendering means search engines see an empty shell. The fix is to get meaningful content into the initial HTML response so pages can actually be indexed.

6. Backend 404s

Endpoints that worked yesterday return 404 today, usually after a regeneration changed a route. Reproduce, trace the missing route, and restore it without disturbing the rest.

How we approach every fix

Our method on every fix is the same: diagnose, reproduce, repair, verify. You get a written summary of what broke and what changed, so the fix is auditable rather than a black box.
