Uptime monitoring, kept on an even keel
Know when your site goes down. Preferably first.
Keel checks your URLs on a schedule, opens an incident after two consecutive failures, and tells your webhook the moment it happens — before your customers compose an email about it.
- Every minute
- The scheduler wakes, checks whatever is due. Free monitors every 5 minutes; Pro every 60 seconds.
- Two failures
- Before an incident opens. One blip is noise, and treated as such.
- 30 days
- Of check history — status, latency, error text — then pruned without ceremony.
What it does
Four things, done properly. The list of things it doesn't do is longer, and we're rather proud of it.
Checks on the minute
HTTP and HEAD checks on a fixed schedule — every 5 minutes on the free plan, every 60 seconds on Pro — comparing the response status against the one you expect.
Incidents, not drama
Two consecutive failures opens an incident and records the reason — HTTP status or fetch error. A single blip is ignored, as it ought to be.
Webhooks, plainly
A POST to any HTTPS endpoint you own, on down, up, or both. The payload is plain JSON with a human-readable summary, so Slack, Discord, and generic receivers all work without adapters.
Honest limits
Three monitors for nothing, fifty for £5 a month. That is the entire schedule — no seats, no add-ons, no telephone calls.
Pricing
Two plans. One of them is free, and it isn't a trick.

The Pro button goes through our payment provider. Plan changes apply to the account, not per monitor.
Steady as she goes.
