A small tool that does one thing carefully
Uptime watches websites and tells you when they stop working. That is the whole product. There is no dashboard of dashboards, no AI assistant, no feature you will never open.
It exists because the alternative is finding out from a customer. A site goes down at 2 AM, nobody notices until nine, and by then the morning’s orders are gone. The fix is not complicated — something has to keep checking, and it has to tell you in a way you will actually believe.
That second part is where most monitoring tools quietly fail. A tool that alerts on every momentary blip trains you to ignore it, and an ignored alert is the same as no alert at all.
So we wait for two consecutive failures before calling a site down, send exactly one email per outage and one when it recovers, and cap how many alerts an account can receive in an hour. Fewer emails, each one worth reading.
How it is built
Every check is stored — not sampled, not averaged. When a chart says your site was down for eleven minutes, that is eleven minutes of recorded checks, not an estimate drawn between two points.
The parts that are easy to get wrong are handled deliberately. Your monitors are reachable only by your own account, never by guessing an address. Every URL is re-verified at the moment we fetch it, so a domain cannot be pointed at a private network after you add it and turn this service into a way to reach somewhere it should not. And a single outage sends a single email, even if one of our servers fails halfway through sending it.
Where it is going
The next things worth building, roughly in order: checks from more than one location so a fault on our side cannot look like a fault on yours, alerts through Slack and SMS, SSL certificate expiry warnings, and public status pages.
If one of those is the thing standing between you and using this, say so — it moves up the list.
