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

Introduction

Hey DEV community! 👋
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?

Why I built UpScout

I decided to fix this by building UpScout. To make the free tier sustainable, I needed server costs to be basically zero, so I built the ping engine in Rust. It handles multi‑region concurrent requests beautifully with tiny memory usage and zero garbage‑collection pauses.

Features

  • 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.

Call to Action

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