Introduction
Uptime Medics is a lightweight, high-performance uptime and incident monitoring platform built in Rust. Designed for DevOps engineers and indie hackers, it offers a seamless way to monitor web services with minimal resource consumption and robust security features. This guide will walk you through getting started with Uptime Medics, exploring its architecture, and diving into a hands-on tutorial.
- Uptime Medics is a single-binary Rust application consuming less than 30 MB of RAM.
- It features zero-signup public community monitoring and enterprise-grade SSRF protection.
- Supports multi-method HTTP probing and intelligent flapping suppression.
The Challenge: Why Uptime Medics Was Built
Existing uptime monitoring solutions often suffer from commercial bloat, resource-heavy architectures, and severe SSRF vulnerabilities. Uptime Medics addresses these issues with a lightweight, high-performance Rust-based platform that offers zero-signup community monitoring and robust SSRF protection.
Core Architecture & Technical Stack Deep-Dive
Uptime Medics is built using Rust 1.82+, leveraging Axum 0.8 and Tokio 1 for asynchronous web API and scheduling. It uses SQLite in WAL mode for efficient data storage and Lettre for reliable SMTP email alerting.
Key Components
- Tokio Prober Loop: Manages hundreds of concurrent probes using bounded semaphores.
- SSRF & DNS Resolver: Multi-tier address blocking to prevent internal network scanning.
- Batched Log Queue: Efficiently writes check logs in transactional batches.
Key Features Breakdown & Practical Benefits
Zero-Signup Community Monitoring
Anyone can immediately submit a public monitor without creating an account. The landing page dynamically juggles 10 random community monitors every 10 seconds alongside live global health telemetry.
Multi-Method HTTP Probing
Supports HEAD, GET, POST, PATCH, PUT, DELETE, and OPTIONS methods with custom headers and payloads up to 64 KB.
Enterprise-Grade SSRF Defense
Multi-tier address blocking protects against loopback, private, link-local, cloud metadata, CGNAT, multicast, and IPv6-mapped spaces.
Real-World Use Cases & Applications
Uptime Medics is ideal for DevOps engineers, indie hackers, public API operators, and self-hosted server environments. Its lightweight architecture and robust security features make it a versatile choice for various monitoring needs.
How It Works: Step-by-Step Workflow
- Submit a monitor via the quick-create form on the homepage.
- The Tokio Prober Loop schedules and executes probes based on the configured interval.
- Probes are validated through the SSRF & DNS Resolver to ensure security.
- Check logs are written to the SQLite database in transactional batches.
- Incident alerts are dispatched via SMTP email with exponential retry backoff.
