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.

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

What you give up building UptimeRobot yourself

  • 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

How to build your own UptimeRobot

Genuinely one of the simpler builds here: 1. A scheduled job that requests a URL and checks the status code — a cron job and an HTTP client. 2. Alert on failure via email, SMS, or a webhook — a well-documented notification pattern. 3. A public status history page — a simple table of pass/fail timestamps rendered as an uptime bar. That's a real, complete uptime monitor. Out of scope: checking from multiple geographic regions so a regional outage doesn't hide from a single-location monitor, which needs distributed infrastructure, and SSL-certificate-expiry monitoring, a small but genuinely separate check to add.

What it actually costs to build

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.

AI agent — with a subscription (Claude Pro/Max, Cursor, etc.)$0 marginal
AI agent — pay-per-use API, no subscription$16–$27 one-time
Hosting, once it's running$0/mo (free tier)
Domain name, if you want your own~$12/yr

UptimeRobot costs $7/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 4 months.

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?

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.
