Atalaya Uptime Monitor
Atalaya (Spanish for watchtower) is an uptime & status page monitoring service running on Cloudflare Workers and Durable Objects allowing checks from multiple regions.
It runs entirely on Cloudflare's free tier, so you get a self-hosted uptime monitor and status page without paying for servers. It's aimed at hobbyists who want control over their monitoring and don't mind living inside Cloudflare's ecosystem.
Live example.
⚠️ 99% of the code has been generated by an AI agent under human supervision, bearing in mind that I haven't used TypeScript before. You have been warned!

Documentation
Read the docs for setup, configuration, alerts, and more.
Development
# Run worker locally
wrangler dev --test-scheduled
# Run status page locally
pnpm dev:pages
# Trigger cron manually
curl "http://localhost:8787/__scheduled?cron=*+*+*+*+*"
Testing
# First build the status page
pnpm build:pages
# Worker tests
pnpm test
# Status page unit tests
pnpm test:pages
# Type checking and linting
pnpm check # worker (typecheck + lint + format)
pnpm check:pages # pages (astro check + tsc + lint)
TODO
- Add support for TLS checks (certificate validity, expiration). Apparently, the Workers API does not support certificate data access, even at the socket level. An external service may be required.
- Refine the status page to look... well... less AI-generated.
- Per-monitor maintenance windows
- Initial support for incident management (manual status overrides, incident timeline).
- Branded status page (simple custom banner).
- Add support for notifications other than webhooks.
