OpenUptime brings uptime checks, alerts and public status pages together. Monitor HTTP, TCP, DNS, cron jobs and databases. Manage monitors and incidents from Claude, Cursor or any MCP client, or use the REST API. Get alerts in Slack, Lark, Telegram, PagerDuty or email. Use the hosted service with a free plan, or self-host the MIT-licensed core with Docker or Cloudflare Workers + Postgres.
