I built a self-hosted daily monitoring bot for Render + Supabase (open source)

The Problem

Every morning I was doing the same thing: opening Render to check if my services were up, then opening Supabase to see how many new users signed up overnight.

It took 5 minutes. Every day. Manual, repetitive, boring.

So I built DevPulse.

What it does

DevPulse runs on your VPS and sends you a daily report automatically:

Render monitoring:

• Service uptime + response time (ping)
• Deploy history with commit messages
• Service status (live / suspended / failed)

Supabase monitoring:

• Per-table row counts
• New records in the last 24h
• Recent entries preview
• Storage bucket listing

Notification channels:

• Telegram
• Discord
• Slack
• Email (SMTP)

How it works

Node.js backend + Express. Config stored in a local JSON file — no database setup needed. A simple web dashboard to configure everything.

You set a daily report time, pick your notification channel, select which Render services and Supabase tables to monitor — and that’s it.

Quick start

git clone https://github.com/rkiilincc/devpulse.git
cd devpulse/backend
npm install
node server.js

Then open frontend/index.html in your browser and configure via UI.

For 24/7 uptime, use PM2:

pm2 start ecosystem.config.js
pm2 save && pm2 startup

Sample report

📊 DevPulse Report
🕐 09:00 - 09.03.2026

🚀 Render Services
🟢 my-api — 142ms
   ✅ Last deploy: live — "fix: auth bug"

🗄 Supabase Tables
📋 waitlist
   👥 Total: 247 rows
   📈 Last 24h: +12 new

Why open source?

I built this for my own SaaS. It solved a real problem for me, so I figured other solo founders on the same stack might find it useful too.
