9,400+ stars on GitHub. One YAML config. Monitoring all your sites and APIs with Telegram alerts in 60 seconds.
Gatus checks HTTP, TCP, DNS, SSH, WebSocket endpoints on schedule. If a site goes down — alert flies to Telegram, Slack, Discord or 30+ other services. Plus a beautiful dashboard with history for clients.
What's appealing:
→ Doesn't wait for traffic to realize the site is down — it pings and checks itself
→ One Go binary, minimal resources
→ Config reads like plain text
→ Built-in status page — can be shown to clients
→ Storage in SQLite/PostgreSQL, metrics for Prometheus
Where I see use: monitoring niche sites, WooCommerce stores, bot APIs. Previously found out about downtime from GSC after a day. Now an alert in Telegram in a minute.
