# UptimeCrow

> Developer-first uptime monitoring and status page platform. Monitor HTTP, TCP, and keyword endpoints from multiple regions; alert on incidents via email, Slack, Discord, PagerDuty, Microsoft Teams, and Telegram; and serve pre-rendered status pages that stay online even when your origin goes down. MIT open-source, self-hostable with Docker. Free forever: 25 monitors, 1 status page, 60-second checks, 60-day history.

UptimeCrow is built for developers and small teams who want production-grade monitoring without the enterprise pricing. The platform pairs a managed cloud offering at uptimecrow.com with a fully self-hostable container stack on GitHub. Status pages are pre-rendered to disk so they remain available even during a customer-side outage. A built-in MCP server exposes monitor state to AI assistants like Claude Code, Cursor, and Windsurf via JSON-RPC over HTTP.

## Core pages

- [Home](https://uptimecrow.com/): Product overview, "your site went down — we caught it first" positioning, hero demo, social proof, dashboard preview, and call-to-action.
- [Pricing](https://uptimecrow.com/pricing): Three tiers — Free ($0, 10 monitors, 5-min checks, 7-day history, email only), Indie ($9/mo, 25 monitors, 1-min checks, 5 status pages, 1-year history, Slack/Discord/PagerDuty/webhooks, custom domain), Pro ($29/mo, 100 monitors, 30s checks, multi-region, 1-year history, 5 seats). Custom plans via email.
- [Docs](https://uptimecrow.com/docs): How to add monitors, configure alerts, create status pages, embed badges, use the REST API and MCP server, and self-host with Docker Compose.
- [MCP Server](https://uptimecrow.com/mcp): Native Model Context Protocol endpoint at /api/mcp (POST JSON-RPC, Bearer-token auth). Tools: get_status_summary, list_monitors, list_active_incidents, get_monitor_detail, list_heartbeats. Lets AI assistants answer "is my API up?" without leaving the editor.
- [Self-Host](https://uptimecrow.com/self-host): MIT-licensed Docker Compose stack — API + Postgres + Redis + BullMQ worker + Vite/nginx web. One command up; deploy to your own VPS in minutes.
- [Heartbeat Monitoring](https://uptimecrow.com/heartbeat-monitoring): Cron and scheduled-task accountability. Tasks ping a unique URL on a schedule; UptimeCrow pages you when the ping is late.

## Key facts

- License: MIT. Source: https://github.com/ozers/uptimecrow.
- Tech stack: Hono + TypeScript on the backend, Postgres 16 + Redis 7 + BullMQ for jobs, React + Vite on the frontend, Drizzle ORM, Amazon SES for email.
- Check types: HTTP (status code + optional keyword), TCP (raw socket), keyword (HTTP with required substring), SSL certificate expiry, domain expiry (WHOIS), heartbeat (inbound ping).
- Confirmation logic: two consecutive failures across multiple regions before an incident is opened, so a single network blip never pages anyone.
- Status pages: pre-rendered to static HTML + JSON on every state change. They survive an origin outage because they don't touch the database to render.
- Integrations: Slack, Discord, custom webhooks, PagerDuty (Events API v2), Microsoft Teams (MessageCard), Telegram bots, email (Amazon SES).
- MCP support: First-class. The same API key authenticates both REST and MCP requests.
- Pricing model: Flat monthly plans, no per-monitor or per-seat surcharges within a tier. Free tier is permanent, not a trial.
- Hosting: Managed at uptimecrow.com; self-host anywhere Docker runs.
