# cron.watch

> Cron job & scheduled-task monitoring — deadman's-snitch check-ins, uptime, latency, and custom metrics. Know your jobs *ran*, not just that they exist. AI-native: connect an MCP client and your agent can sign you up, create monitors, and push data with zero console clicking.

cron.watch watches cron jobs, systemd timers, background workers, and HTTP endpoints. Every job checks in over HTTP, WebSocket, email, or a DNS lookup; if a check-in is missing, late, or drifts off its numbers, we alert you. You pay per monitor, never per seat — unlimited team members. Pricing: 10 monitors free for 3 months, then $0.50/monitor/month ($10/yr prepaid or $5/mo minimum).

This file follows the llms.txt convention (https://llmstxt.org). The full single-file docs an LLM or agent can read end-to-end are at https://cron.watch/llms-full.txt.

## Start here
- [Sign up / early access](https://cron.watch/#get): join the waitlist now; product API signup will be `POST https://api.cron.watch/v1/signup`.
- [MCP server](https://github.com/bitgeek/cronwatch-mcp): add cron.watch to Claude, Cursor, or any MCP client. Tools: `signup`, `create_organization`, `invite_member`, `create_monitor`, `list_monitors`, `check_in`, `push_metric`, `get_monitor`.
- [Full docs (one file)](https://cron.watch/llms-full.txt): signup → organizations → monitors → sending data, with copy-paste examples.

## Concepts
- [Check-in methods](https://cron.watch/#checkin): HTTP snitch (`curl https://cron.watch/s/<slug>`), WebSocket heartbeat (live progress), email (`<slug>@cron.watch`), DNS lookup (`dig <slug>.dns.cron.watch` — the cheapest health check).
- [Organizations & teams](https://cron.watch/llms-full.txt): an organization holds monitors and members; billing is per monitor; members are unlimited and free.
- [Sending data & metrics](https://cron.watch/llms-full.txt): attach values (rows, latency_ms, queue depth, exit code) and metadata (host, region, version) to any check-in; charted, baselined, and alertable.
- [Monitor types](https://cron.watch/llms-full.txt): cron, timer, latency, uptime, fleet/quorum (many reporters → one monitor), heartbeat.
