OpenUptime
Open-source uptime monitoring and public status pages
About OpenUptime
OpenUptime is an open-source uptime monitor and status page tool under the MIT license. It checks HTTP and HTTPS endpoints with keyword matching, TCP, DNS, WebSocket, PostgreSQL, MySQL and Redis, and offers heartbeat monitors for cron jobs, domain expiry checks and optional multi-region checks from your own probes. Incidents, maintenance windows and public status pages with email and RSS subscriptions are built in. Alerts go to Slack, Discord, Microsoft Teams, Telegram, Lark, ntfy, PagerDuty, webhooks, email and an iOS app. A REST API and an MCP server let scripts and AI agents create monitors and manage incidents. You can self-host it on Cloudflare Workers with Postgres or as a single Docker container, or use the hosted version, which has a free tier.
