Uptime Kuma: Pricing, Features & Alternatives

Uptime Kuma is the self-hosted answer here, and one of the most-starred projects on GitHub. One Docker container gives you HTTP(S), keyword, JSON-query, TCP, ping, DNS, WebSocket, Docker and push monitors at intervals down to 20 seconds, with multiple status pages mapped to your own domains and alerts to Telegram, Discord, Slack, SMTP and 90-odd other services. Version 2 is current. The catch is one every self-hosted monitor has: if it runs on the same box, region or provider as the thing it watches, it goes down with it. Host it somewhere your outage cannot reach.
