Monitors

Scheduled uptime monitoring for your URLs: the worker checks each monitor on a fixed interval, records history, opens incidents and sends webhook alerts. All data is private to your management key.

How it works

Each monitor runs one safe HTTP check per interval through the same engine as the instant tools — full SSRF validation on every run. Consecutive failures open an incident; recovery closes it; your webhook (if configured) is notified once per transition.

Your management key

The key is created together with your first monitor and shown exactly once — it is the only credential for your monitors, and we store only its hash. Save the link /monitors/…?key=… or keep the key; a lost key cannot be recovered.

Storage and auto-cleanup

Monitors live as long as their key is used: every visit to this list (via your saved link) refreshes the activity mark. If the key is not used for 60 days by default, the monitor is auto-paused — checks stop; after 90 days of inactivity it is deleted together with its history. Monitors whose webhook receiver is alive are exempt from the cleanup, and so are monitors attached to your account. To avoid losing anything, open this page via your saved link at least once every couple of months.
