PYLONMON
Website & server uptime monitoring

Know the second
your site goes down.

PylonMon watches your website, API, or server from outside your network — checking as often as every 30 seconds and paging you the moment it stops responding, so you hear about downtime before your customers do.

# PylonMon checks your site from outside your network:
GET https://your-site.com   200 OK · 142ms

# the moment it stops responding, you're paged:
🔴 your-site.com is DOWN — connection timed out · confirmed on recheck

How uptime monitoring works

1 · ADD

Point us at a URL

Paste your website, API endpoint, or server address. No agent, no code, no DNS changes — just the address you want watched.

2 · WATCH

We check from outside

PylonMon polls it from off your network, as often as every 30 seconds, checking the status code, response time, and — if you want — that the page actually contains the text it should.

3 · PAGE

Down pages you

The instant it can't reach your site, you're alerted — email, Slack, Discord, SMS, voice, webhook, PagerDuty or Opsgenie, with escalation ladders.

Uptime monitoring that reaches you — and doesn't cry wolf

A monitor is only useful if you trust it. Before PylonMon pages you, it immediately re-checks a failed poll from scratch, and you can require a few consecutive failures — so a one-second network blip doesn't wake you at 3am, but a real outage still gets to you in seconds.

And a 200 OK isn't the whole story: a broken deploy can serve a blank white page that still returns 200. PylonMon can assert the response actually contains the text it should (or that an error string is absent), so you catch the outages a plain status check sleeps through.

Everything you can keep an eye on

When something breaks you can publish a branded status page so customers self-serve instead of flooding your inbox — and if you run backups or cron jobs, the same account does heartbeat / dead-man's-switch monitoring too. See every monitor type →

Why external matters: a monitor that runs inside your own network dies with it — when the box goes down, so does the thing meant to tell you. PylonMon watches from off-site, so it still sees (and reports) an outage even when your whole environment is dark.

Common questions

Do I need to install anything?

No. Uptime checks run entirely from our side — you just give us a URL or address. There's no agent on your servers and nothing to maintain.

How fast will I know about downtime?

Checks run as often as every 30 seconds (1-minute on the free plan). Alerts fire on the first confirmed state change, so you hear about a real outage in seconds — without repeat nagging once you've been told.

Will I get woken up by false alarms?

That's exactly what the confirmation re-check and consecutive-failure threshold are for. A blip won't page you; a genuine outage will.

What does it cost?

Free forever for 20 monitors with 1-minute checks and HTTP/S, TCP & ping monitors. Paid tiers start at $4/mo for 30-second intervals, more monitors, SMS/voice, DNS, and certificate/domain-expiry monitoring. See pricing →
