WatchTower checks your endpoints at the interval you choose. When a check fails, it re-checks to confirm the outage before alerting you, so brief blips don’t trigger a page. It auto-resolves the incident once the endpoint recovers. No per-seat fees.
Paste a URL. WatchTower handles every step, from the first check to closing the incident.
HTTP request at your interval — 30s to 24h. Validates status code, response time, and (optionally) keyword match in the body.
Set how many failed checks in a row count as down (default 3). No more pages for flaky endpoints or one-off blips.
Email, Slack, Discord, PagerDuty, or signed webhook, sent the moment a monitor is confirmed down.
As soon as the endpoint responds again, the incident closes on its own, with the downtime duration and check history saved.
The established players bill per seat and lock the useful parts behind a sales call. WatchTower is flat-rate and self-serve. You pay for the monitoring, not the overhead.
