Uptime Monitor
Scheduled, multi-region monitoring that watches your site around the clock and alerts you the moment it goes down or slows. A hosted premium service, in development.
Always-on monitoring, not a one-off check
The free tools on this site answer "is it working right now?". The Uptime Monitor answers "has it stayed working, and will I know the instant it doesn't?". It runs on our infrastructure — checking your site on a schedule from multiple regions, recording the response over time, and alerting you the moment something breaks. It's the premium counterpart to the free Is It Down? check.
Multi-region checks
We watch your site from several locations, so you know if it's down everywhere or just one region.
Scheduled intervals
Automated checks around the clock — every minute on premium plans — not a one-off click.
TTFB & status history
We record real status codes and response time over hours and days, not a single snapshot.
Instant alerts
Email and webhook notifications the moment a check fails, so you hear it from us, not your client.
Want early access? The monitor ships as part of our premium and API plans. In the meantime, explore the developer tooling on the API & Widget page.
What an uptime monitor does
An uptime monitor is a service that checks your website or API on a fixed schedule, automatically, from servers around the world — and tells you the instant it stops responding. Instead of finding out your site is down when a customer emails you, you get an alert within a minute or two and a record of exactly when it started. Good monitors go beyond a simple up/down dot: they track response time, read the real HTTP status code, and watch from several regions so a regional outage doesn't fly under the radar.
For anyone running a site for themselves or for clients, it's the difference between hearing about a problem from your monitoring and hearing about it from your boss.
How to read uptime & alerts
Two numbers matter most. Uptime percentage is the share of checks that succeeded over a window — "three nines" (99.9%) allows roughly 43 minutes of downtime a month, while 99.99% allows about 4 minutes. Response time trends catch the slow decline before it becomes an outage: a TTFB that creeps upward week over week is an early warning that a single up/down check would miss entirely. Set alert thresholds for both, and you'll be told about trouble before your visitors are.
Frequently asked questions
- How is this different from the Is It Down? tool?
- The Is It Down? tool is a single, on-demand check from your own browser. The Uptime Monitor is a hosted service that checks your site automatically, on a schedule, from multiple regions, and keeps a history — so it catches outages that happen while you're not looking.
- Why does continuous monitoring need a backend?
- A browser only checks when you open the page, from one location, and can't read cross-origin status codes. Real monitoring runs on servers that probe your site 24/7 from several regions, read the true HTTP response, and store the timeline. That's infrastructure, not a script.
- Will there be a free tier?
- Pricing isn't finalised yet. The plan is a generous free allowance for a few monitors at a relaxed interval, with premium tiers unlocking more monitors, faster checks, more regions and longer history.
- What will it alert me about?
- Downtime first and foremost, plus slow responses (a TTFB threshold you set) and — further out — certificate expiry, so a lapsing SSL cert never takes you by surprise.
