# Sentinely

> Sentinely is monitoring for cron jobs, AI agents, websites and servers. It alerts you when a scheduled job or agent stops checking in (heartbeat monitoring), when a website or API goes down (uptime monitoring), when a Linux server runs out of headroom, and when AWS spend spikes. Plans are $19, $79 and $249 per month, each with a 14-day trial. There is no free plan.

## Key facts

- Agent Pulse (heartbeat monitoring): each job gets a ping URL (GET, HEAD or POST https://sentinely.app/api/beat/<token>). Intervals from every minute to daily, plus a grace period. A missed or failed heartbeat opens an incident and alerts by email and an optional Slack-compatible HTTPS webhook; a recovery notice follows.
- Ping (uptime monitoring): HTTP, HTTPS, TCP and DNS checks every 1, 3, 5, 10 or 15 minutes from a single check region (multi-region checks are not offered). SSL expiry alerts, email and Slack alerts, Freshping import.
- Pulse (server monitoring): an agent installed with one command reports CPU, memory, disk, network, load, services and ports from Linux servers. Threshold alerts, stale-agent detection, plain-English Clarity Mode. Not an APM, tracer or log-search tool.
- Status: public status pages showing only the monitors and incidents you choose, on every plan.
- Guard: AWS-only cost and resource monitoring with read-only credentials. Agency and Scale plans.
- Every plan starts with a 14-day trial. There is no free plan.
