Stuck in a loop where every AI fix breaks something else? Here’s when to stop

It starts with one small bug. You ask the AI to fix it. It says “Fixed!”, and now the login page is broken too. You ask it to fix that, and the dashboard stops loading. An hour later you’re further from a working app than when you started. If that sounds familiar, you’re not doing it wrong. It’s a predictable pattern, and there are ways out.

Why AI fixes break other things

• It fixes the symptom it can see. “The page is stuck loading” gets a loading-state fix, even when the real cause is a database rule or a setting.
• It only sees part of the system. The code is in front of it. Your Supabase settings, hosting configuration, Stripe dashboard and production secrets often aren’t.
• Every attempt adds code. A failed fix is rarely removed cleanly. After a few rounds there are three half-solutions fighting each other.
• “It works” is judged too early. Many bugs depend on timing, on being logged in, or on the live environment, so a fix can look right in the preview and fail for real users.

Five ways to break the loop yourself

1. Go back to the last version that worked

Don’t pile fixes on top of fixes. All three big tools let you rewind:

• Lovable saves every change as a version. Open version history and use Revert (“Revert to this version”), or bookmark known-good versions before a big change. Lovable’s docs note that reverting restores code only: it doesn’t roll back database data or migrations.
• Bolt saves a version after every prompt. Use Version history (the clock icon) and Restore this version. Per Bolt’s docs, restoring doesn’t change your Bolt or Supabase database either.
• Cursor creates checkpoints before the Agent makes significant changes. Use Restore Checkpoint on an earlier message. Cursor’s docs say checkpoints are local and separate from Git, so use Git for anything permanent.

2. Ask before you build

In Lovable, switch the project chat to Chat mode and ask “why is this happening?”. Per Lovable’s docs, Chat mode reads your project and never changes code or data, and each message is priced as a chat message (typically a fraction of a credit, covered first by a daily allowance). Only switch to Build once the explanation makes sense to you. For bigger changes, Plan mode writes a plan you can review before any code is touched.

3. Give it the real error

“It’s broken” gets a guess. Open DevTools (F12), copy the first red line from the Console, or the failing request and its status from the Network tab, and paste that. Our guides on blank screens, empty arrays and 42501 errors show what the common ones mean.

4. One change per prompt, then test

Ask for one thing, test it in the preview (and the live app if it’s auth, payments or deployment), then move on. If something breaks, you know exactly which change did it, and which version to go back to.

5. Write the rules down once

Lovable’s Knowledge lets you set persistent instructions it considers on every edit, at project or workspace level. Good candidates:

• “Never use the Supabase secret or service_role key in frontend code.”
• “Never disable Row Level Security or add policies that allow everyone, to fix an error.”
• “Every new table needs explicit grants, RLS and policies in the same migration.”
• “Explain the cause before changing code, and change one thing at a time.”

Not sure which of these is your problem? The free health check looks at your live app in seconds, or request a free scan and we’ll tell you what we find.

Signs the problem isn’t the prompt

• The same bug comes back after two or three different fixes
• It only happens on the live site, not in the preview
• It involves something outside the code: Supabase settings, grants and RLS, hosting, secrets, Stripe, Google login
• The AI suggests turning off a security feature to make the error go away
• You can no longer tell which of the last ten changes are still needed

Some classic examples where AI loops are common: the app freezes after login, payments that don’t unlock features, and Google login going to localhost.

Fixes an AI should never make for you

• Turning off RLS or adding an “allow all” policy to get data to show (why that leaks data)
• Switching the frontend to the service_role or secret key (why that’s a master key)
• Granting everything to everyone to make a 42501 go away (the October 30 checklist)

If you accepted one of these during a loop, revert it or get it checked, even if the app works now.

What a human review gives you

A person looks at the code and the parts the AI can’t see, finds the actual cause, and tells you what to change, or changes it. At fixed prices, not hourly:
