mttrly for Vibe Coders

A DevOps safety net for AI-assisted developers

You build amazing things with Cursor, Replit, and AI. But when production breaks at 2am, you're lost. mttrly is your DevOps safety net.

🎨 White Screen After Deploy

Built with Cursor, worked locally. Production: blank page. You're lost.

Panic
Site down, no idea why

Diagnose
WebsiteDown recipe checks all layers
🎯
Found
Nginx config error line 47
Fixed
Fix typo → reload → online
Before
Open a terminal, search noisy logs, reconstruct the context, and hope the first guess is right.
$ ssh prod-server
$ journalctl -u nginx -n 1000 | grep ERROR
...scrolling through noise...
...still no idea where the error is...
After
A structured diagnostic narrows the problem to the exact file and line before you choose a fix.
✓ Server reachable
✓ Ports open
✗ Nginx config error line 47
→ "listen 80" missing semicolon

Fix it, I'll reload

The Problem

  • Deployed with Cursor but getting 502 errors
  • No idea how to read server logs
  • SSH feels like black magic
  • Just want to ship features, not learn ops

The Solution

mttrly gathers live evidence, explains it in plain English, and offers a scoped next action. The terminal stops being the place where you first reconstruct the incident.

What is Vibe Coding?

Vibe coding is a new approach to software development where AI tools like Cursor, Replit, GitHub Copilot, and v0 do most of the heavy lifting. You describe what you want, the AI writes the code, and you ship it. The problem? When something breaks in production, the AI can't help you fix servers.

Common Scenarios for Vibe Coders

White screen after deploy

Problem: Your Next.js app shows a blank page in production but works locally. You built it with Cursor, everything worked. Now: nothing.

How mttrly helps: You: "why is my site down?" → Bro runs the WebsiteDown diagnostic recipe → checks the server, nginx, and app process → reports the exact config error and line → you edit the file, request a guarded reload, and see verification in the same incident trail.

App crashes randomly

Problem: Your Replit project dies every few hours. No pattern. Just... crashes.

How mttrly helps: You: "everything is slow" → Bro runs HighLatency diagnostic → checks CPU (23%), disk (45%), RAM (94% — HIGH) → node.js using 3.2GB → found 127 "heap out of memory" warnings → explains "memory leak from deploy 2 hours ago" → offers restart or rollback.

Errors after deploy

Problem: Deployed your changes. Now getting 500 errors. Users are complaining.

How mttrly helps: You: "show me errors" → Bro finds 23 errors in last 10 minutes → all "TypeError: Cannot read property 'id' of undefined" → /api/users.js line 47 → started 8 min ago (right after deploy) → suggests "this is new, want to roll back?"

Why not just ask ChatGPT to fix it?

AI can explain concepts and suggest solutions, but it can't see your actual server. It doesn't know your current CPU usage, your latest error logs, or which services are running. mttrly bridges this gap by giving you real-time visibility into your server — in language you understand.

Illustrative example: Your Cursor deploy is broken

⚠️ Alert: 502 Bad Gateway on api.myapp.com
You: /logs api
mttrly: Found error - "ECONNREFUSED" on port 3000. Your Node process crashed.
You: /restart api
✅ Service restarted. App is online.
