Uptime monitoring

The best free uptime monitors in 2026

Every uptime monitor claims to be the best. This is the honest version: four solid free options, what each one is genuinely good at, and where each one falls short — including ours.

How to choose

Free uptime monitors mostly differ on three things: how many sites you can watch for free, how often they check, and what happens after a check fails. The biggest free tier isn’t always the right answer — a monitor that pages you for every transient blip trains you to ignore it. Here’s where each tool lands.

UptimeRobot

Best for: watching many sites for free

The biggest free tier in the category — 50 monitors at 5-minute checks. If you need to keep an eye on a lot of personal projects without paying, this is the pragmatic choice. The trade-off is noise: a single failed check can alert you, so expect the occasional false alarm.

Better Stack

Best for: teams that want observability too

More than a monitor — logs, incident management and on-call scheduling in one platform. Powerful if you need all of it, and priced and scoped like an observability suite. Overkill if you just want to know your site is up.

StatusCake

Best for: many test locations and a generous free tier

A long-standing monitor with 30+ test locations and a roomy free plan. A solid all-rounder; the alert pipeline leans more “fire on failure” than “confirm, then fire.”

Monitrova

Best for: no-noise alerts and WordPress / WooCommerce sites

A focused monitor built around one rule: never page you on a single failed check. A failure seen from Europe is re-confirmed from the US before it alerts, which removes almost all false alarms. The free tier is smaller (one site), but it classifies backend errors and adds a WordPress timeline that names what changed. That’s us — and we think the honesty is the point.

No affiliate links, no “winner”

We didn’t rank these one to four, because the right pick depends on what you need. If raw free capacity matters most, UptimeRobot wins. If you want alerts you can trust and you run WordPress or WooCommerce, that’s where Monitrova earns its place. Try the free tools below and decide for yourself.

Frequently asked questions

What’s the best completely free uptime monitor?
For raw capacity, UptimeRobot’s free tier (50 monitors) is the largest. For alerts you can trust without false alarms, Monitrova confirms a failure from a second location before paging you. “Best” depends on whether you optimise for quantity or signal quality.
Do free uptime monitors really work?
Yes — for basic up/down checks at intervals (typically 1–5 minutes), free tiers are genuinely useful. The limits are usually check frequency, the number of sites, and how advanced the alerting is.
Why do uptime monitors send false alarms?
Most alert the instant a single check fails — but a single failure is often a transient network blip or a firewall briefly blocking the checker’s IP. Monitors that re-confirm from a second location before alerting remove almost all of these.
Can I monitor a WordPress or WooCommerce site?
Any of these will check that your site responds. Monitrova goes further with a WordPress Site Agent and a WooCommerce checkout health check — because a homepage being “up” doesn’t mean checkout works.
How often should a monitor check my site?
Every 1–5 minutes is plenty for most sites. More frequent checks catch incidents marginally faster but add load and, on noisy monitors, more false alarms.
