Can I code UptimeRobot?

Ping a URL on a schedule, alert if it fails, log the history. This is about as mechanical as monitoring gets, and one of the cleanest evening builds on the whole register.

VIBE SCORE 95/100

how this is worked out

Why CanICodeThis says Build it

  • A scheduled job that requests a URL and checks the status code is a cron job and an HTTP client
  • Alerting on failure (email, SMS, or a webhook) is a well-documented notification pattern
  • A public status history page is a simple table of pass/fail timestamps rendered as an uptime bar

Read before building

  • Checking from multiple geographic regions (so a regional outage doesn't hide from a single-location monitor) needs distributed infrastructure
  • Their SSL-certificate-expiry and domain-expiry monitoring are small but genuinely separate checks to add
  • Alert-fatigue features (only notify after N consecutive failures) matter more than they seem at first

The build spec

Build me an uptime monitor: for a list of URLs, check them every few minutes from a scheduled job, log the response time and status, and send an email alert after 2 consecutive failures (and a recovery email when it comes back). A simple public status page showing each monitor's uptime percentage and a pass/fail history bar.

Questions

Can I code UptimeRobot?

Build it. Ping a URL on a schedule, alert if it fails, log the history. This is about as mechanical as monitoring gets, and one of the cleanest evening builds on the whole register.

How much does UptimeRobot cost?

UptimeRobot costs $7/mo (about $84/yr) as of 2026-08. That's what a working rebuild would save you.

What do I lose by building it myself?

Checking from multiple geographic regions (so a regional outage doesn't hide from a single-location monitor) needs distributed infrastructure Their SSL-certificate-expiry and domain-expiry monitoring are small but genuinely separate checks to add Alert-fatigue features (only notify after N consecutive failures) matter more than they seem at first

Is there a free alternative to UptimeRobot I don't have to build?

Yes — Uptime Kuma are open-source options worth trying before you build your own. Details are in the standard parts section on this page.
