When Perch is the better pick

You want the fastest free alerts. 1-minute checks catch outages roughly five times faster than a 5-minute interval — the difference between a blip and a bad morning.

Your team lives in chat. Alerts go straight to Telegram, Discord, or Slack (or any webhook) so nobody's refreshing an inbox during an incident.

You want a status page you'd actually share. Every Perch monitor can back a clean public status page with uptime and response-time history — free.

Where UptimeRobot still wins: its free plan allows 50 monitors, which is generous if you need to watch many endpoints and 5-minute checks are fine. Pick the tool that matches what you actually need.

FAQ

Is Perch really a free UptimeRobot alternative?
Yes. Perch's core — monitoring, chat alerts, and a public status page — is free with no credit card. The biggest practical difference is that Perch checks every 1 minute on the free plan, where many free tools check every 5 minutes.

Why does the check interval matter?
The interval is your worst-case time-to-know. At 5 minutes, an outage can run for up to five minutes before you're alerted; at 1 minute, you hear about it roughly five times sooner. For a checkout page or API, those minutes are the whole point of monitoring.

Can I move my monitors over easily?
There's nothing to migrate — add your URLs as monitors, attach a Telegram/Discord/Slack webhook or generic webhook, and you're live in a couple of minutes. Try a one-off check first with no account.

Is UptimeRobot a bad tool?
No — it's a solid, popular service and its free plan allows a generous 50 monitors. Perch simply gives away the things that usually cost extra: 1-minute checks, chat-first alerts, and a modern status page.
