Uptime monitoring

Know before your customers do

We check your site around the clock and email you the moment it stops answering — with the status code, the response time and how long it has been down.

What we watch

Four kinds of check, one dashboard

Most outages are not dramatic. A certificate lapses, a cron job stops running, a deploy returns the wrong page. These are the checks that catch them.

Websites and APIs

Status code, response time and an optional keyword that has to be on the page — or must not be.

Certificate expiry

We read the certificate straight from the handshake and warn you 30, 14, 7, 3 and 1 days before it lapses.

Domain expiry

The registry says when your domain runs out. We check it daily so a renewal is never a surprise.

Cron heartbeats

Your job pings a URL when it finishes. Silence past the window you set raises an incident.

About us

Alerts you can act on

Uptime Monitor exists to answer one question quickly and honestly: is it up? Every alert names what failed, when it started and what the response actually was, so the first minute is spent fixing rather than diagnosing.

A check has to fail twice in a row before anyone is emailed, so a single blip stays quiet. When it recovers, you get one message with the total downtime — and nothing else.

How to get started

Watching your first site takes a minute

Paste a URL, confirm where the alerts should go, and leave it running.

1

Add a monitor

Paste the URL. Pick how often it should be checked and, if you want, a word that has to appear on the page.

  • Websites and APIs
  • Keyword matching
  • Custom status codes

2

Confirm your alerts

Add the addresses that should hear about downtime. Each one confirms itself before anything is sent.

  • Verified addresses only
  • Route per monitor
  • Recovery notices too

3

Publish a status page

Turn on a public page for the services your customers care about, with ninety days of history.

  • Your own address
  • Incident notes
  • No internal URLs shown

Why choose us

Quiet until it matters

A monitoring tool earns its place by being ignorable. Ours is built to stay silent until something is genuinely wrong.

No alert storms

Two failures to open an incident, one message an hour while it lasts, and a hard cap after that.

History that survives

Daily uptime is kept even after the detailed checks are pruned, so your status page keeps its record.

Careful by default

Monitors only reach the public internet, and a status page never shows the address you are actually checking.
