What to Do When Your AI-Built App Breaks: A Complete Guide

Step-by-step guide for non-technical founders when things go wrong

Published 2026-03-12

You built your app with Lovable, Bolt, v0, or another AI tool. It was working fine. Then something broke — maybe after an update, maybe randomly, maybe you're not sure when. Now your users can't log in, pages show errors, or the whole app is down.

Take a deep breath. This happens to everyone, and it's fixable. Here's exactly what to do.

Step 1: Don't Panic (and Don't Make Random Changes)

The worst thing you can do is start clicking buttons and making changes hoping something works. Every random change could make things worse and harder to diagnose. Before touching anything:

Take a screenshot of any error messages you see
Note exactly when the problem started (or when you first noticed)
Check if the problem affects all users or just you

Step 2: Check the Basics

Many "broken" apps have simple causes:

Is the site actually down? Try accessing it from a different browser or device. It might be a browser cache issue.
Check your domain/hosting: Did your domain expire? Is your hosting account active? Check Netlify/Vercel/Supabase dashboards for status.
Check your email: Look for any alerts from your hosting provider, domain registrar, or Supabase about expiring plans, exceeded limits, or policy violations.

Step 3: Identify the Type of Problem

What You See	Likely Problem	Severity
Blank white page	JavaScript error or build failure	Medium
"404 Not Found"	Routing or deployment issue	Low-Medium
"500 Internal Server Error"	Backend/database error	Medium-High
Login doesn't work	Authentication configuration issue	Medium
Can't load any data	Database connection or RLS issue	Medium-High
"This site can't be reached"	Domain/DNS/hosting down	High

Step 4: Check Your AI Tool's Status

Sometimes the problem isn't your app — it's the platform:

Supabase: Check status.supabase.com
Vercel: Check vercel-status.com
Netlify: Check netlifystatus.com

If the platform is having issues, wait for them to resolve it. No developer can fix a platform outage.

Step 5: Try the AI Tool First

Before hiring a developer, try asking the AI tool to fix it:

Describe the problem clearly in the AI tool's chat
Paste any error messages you see
If the AI generates a fix, try it

If the AI can't fix it after 2-3 attempts, it's time for human help.

Step 6: Get Human Help

When the AI can't fix it, a real developer can. Here's how to describe your problem effectively:

What was working before: "Login was working fine until yesterday"
What's broken now: "Users see an error when they try to log in"
What changed: "I asked Lovable to add a new feature" or "Nothing, it just stopped working"
Screenshots: Include screenshots of the error

Post your task on humans fix ai and a verified developer who specializes in AI-built apps will pick it up and fix it — typically within 1-3 days.

Step 7: Prevent Future Breakage

Once your app is fixed, reduce the risk of it breaking again:

Make small changes: Don't ask the AI to change 10 things at once
Test after each change: Verify the app still works before making more changes
Keep backups: Use version control (Git) so you can go back if something breaks
Monitor uptime: Use a free service like UptimeRobot to get alerts when your site goes down
