Every website and app, vibe-coded or not, hides front-end and server errors in the background, especially once there are real users. FaultFixer catches these issues, generates an AI-powered diagnosis, & notifies you across multiple channels. The magic: it plugs into Claude, Codex, Cursor & other AI tools beautifully over MCP so your AI fixes the bug with full context. And, you always keep staying inside your AI tool. Just say "list issues" to your Claude, Cursor.. (and "fix issues" later on).
Hey Product Hunt 👋
I've spent years in uptime monitoring, and one thing never changed: by the time you hear about a bug, a real user already hit it. That's even truer now with so many vibe-coded sites/apps that ship fast but with errors in the background.
I'm currently vibe-coding a web app with a friend, and we had lots of:
💬 "hey, x feature is not working"
🧑💻 "ok, share the console logs with me"
…and me copy-pasting all that into the AI dev tool I use for fixes.
I built FaultFixer to close that gap.
It does three things:
🔎 Detects front-end and server errors the moment they happen
🧠 Diagnoses each one with an AI analysis of the likely root cause — not just a stack trace
🔌 Connects to your AI dev tools over MCP. I just say "list issues" (and usually "fix issues" right after)
🔔 Notifies you across the channels you already use
It's built to be a diagnosis layer, not a blind auto-fixer. You (and your AI) stay in the loop and verify before shipping.
How does the MCP setup actually feel in practice, especially with Cursor. Does it surface enough context for the AI to fix things confidently, or do you still end up copy pasting stack traces back and forth?
This is exactly what vibe coders like me need. From time to time I see the site break, I just can't tell why. Now I can close that gap. Good launch.
Vibe-coding made me lazy at debugging. I just assume it all works. So, having them caought and everything working inside Claude is exactly what I need. Nice work.
