I built an uptime monitor in Rust because I hate paywalls for Webhooks

rust dev.to

Hey DEV community! šŸ‘‹

I recently got frustrated with standard monitoring tools. It feels like every tool out there puts simple integrations (like Discord, Slack, or Webhooks) behind a premium paywall. Sending a webhook costs fractions of a cent, so why are we paying $15+/month for it?

I decided to fix this by building UpScout.

Why Rust? šŸ¦€

To make the free tier sustainable, I needed server costs to be basically zero. I built the ping engine in Rust. It handles multi-region concurrent requests beautifully with tiny memory usage and zero Garbage Collection pauses.

The Result

Because the backend is so cheap to run, I’m doing something a bit crazy with the pricing:

  • Free Tier: 50 monitors (checked every 4 minutes).
  • Unlocked Alerts: Webhooks, Discord, Slack, and Telegram are 100% FREE for all users.
  • Dark Mode: Built in React, because light mode is a crime.

I just launched it and would absolutely love your feedback on the speed, the UI, and the architecture!
