Check your live app from inside Lovable
Lovable can call outside tools while you chat with it. Add VibeFix once, and when something in your published app breaks, you can ask Lovable and it gets an answer from VibeFix, an AI agent that tests live apps the way a first customer would.
It takes about a minute, and it works on every Lovable plan, including free.
Add VibeFix to Lovable
- In Lovable, open Connectors in the left sidebar.
- Press + at the top right, then choose MCP server.
- Fill in:
- Server name:
VibeFix - Server URL:
https://vibe-fixer.com/mcp - Authentication: OAuth (the default)
- Server name:
- Press Add & authorize. A VibeFix window opens. Sign in, then press Allow.
Lovable now shows VibeFix: Connected.
Use it
Open your project, switch the chat to Chat mode (it's free and changes no code), and ask in plain words, for example:
"Use the VibeFix connector: my published app's Sign in button does nothing for new visitors. What's wrong?"
Lovable asks VibeFix and shows you its answer: the most likely cause, what would confirm it, and what a fix involves. Good things to ask about:
- a button that does nothing
- a blank page after publishing
- a sign-in or sign-up that fails
- data that won't save
- something that worked yesterday and broke after a change
Want the real test?
The connector answers from your description. To see what a first customer actually hits, paste your app's link at vibe-fixer.com: an AI agent goes through your live app on a phone and a computer and tells you how many problems it finds. Free, no account.
Still stuck?
Paste your app’s link for a free test — no account. Your AI agent goes through it like a first customer, shows you what breaks, then fixes it while you watch.
