Free Website Uptime Monitoring: Best Tools Compared (2026)
October 3, 2026 · 6 min read
Free website uptime monitoring is easy to find. Most of the big monitoring companies have a free plan, and a couple of tools are completely free if you're willing to run them yourself. The catch is in the details: how often your site is checked, who you're allowed to use it for, and which alerts you actually get.
This guide compares the best free uptime monitoring tools, explains what you give up on a free plan, and shows when a cheap paid plan is the better deal for a business website.
What to look for in a free uptime monitor
Every uptime monitor does the same basic job: it loads your website on a schedule and alerts you when it stops working. The differences that matter are:
- Check interval: how often your site is checked. Free plans usually check every 3 to 5 minutes. Paid plans check every minute or faster.
- Number of monitors: how many websites or pages you can watch.
- Alerts: email is standard. Text messages and phone calls are often limited or paid extras.
- False alarm protection: good tools double-check from a second location before telling you your site is down.
- SSL and domain expiry alerts: a warning before your security certificate or domain name runs out.
- Status page: a public page that shows your customers whether your site is up.
- Commercial use: some free plans are meant for hobby projects, not business websites.
If you're new to all of this, our guide to what website monitoring is and why it matters covers the basics first.
The best free website uptime monitoring tools
Prices and limits below were checked in October 2026. Free plans change often, so confirm on each company's pricing page before you sign up.
UptimeRobot
UptimeRobot is the best-known free uptime monitor. The free plan includes 50 monitors checked every 5 minutes, email alerts, and one basic status page. That's generous, but UptimeRobot describes the free plan as a fit for hobby and non-profit projects. Their cheapest paid plan, Solo, adds 1-minute checks and SSL monitoring for about $12 to $13 a month.
Best for: personal sites and side projects that need lots of monitors.
Better Stack
Better Stack's free plan includes 10 monitors checked every 3 minutes, plus a status page and email alerts. It's a polished tool aimed at software teams, with extras like incident management and on-call schedules. Paid uptime plans start at around $25 a month.
Best for: developers and tech teams who want a modern dashboard.
StatusCake
StatusCake's free plan includes 10 uptime monitors checked every 5 minutes, plus 1 page speed monitor, 1 SSL monitor, and 1 domain monitor. Status pages aren't included on the free plan. The cheapest paid plan starts at about $20 a month (billed yearly) and adds 1-minute checks.
Best for: small sites that want SSL and domain checks without paying.
Uptime Kuma
Uptime Kuma is completely free and open source, with no limits on monitors or check frequency. The catch is that you install and run it yourself, on your own server. That means some technical setup, a server bill, and one important weakness: if the server running Uptime Kuma goes down, your monitoring goes down with it.
Best for: technical users who already run their own servers.
Pingdom
Pingdom is one of the oldest names in uptime monitoring, but it has no free plan, only a free trial. Paid plans start at roughly $15 to $18 a month for 10 uptime checks.
Best for: larger businesses that want a long-established brand.
ValueTheWebsite
ValueTheWebsite monitoring doesn't have a free plan, but it starts at $4.99 a month for 10 monitors checked every minute from 2 locations. That's 5 times more often than most free plans, for less than half the price of most paid ones. Every plan includes email alerts that are double-checked before they're sent, SSL and domain expiry warnings, API checks, and a public status page.
Best for: small business websites that want fast, reliable checks without paying $12 or more a month.

Is free uptime monitoring good enough?
For a personal blog or a side project, yes. A free plan is far better than no monitoring at all.
For a business website, the check interval is where free plans fall short. With 5-minute checks, your site can be down for up to 5 minutes before the monitor even notices, and longer before the alert reaches you. With 1-minute checks, you hear about it almost straight away.
It also helps to think about what an hour of downtime costs you. If your website brings in calls, bookings, or sales, one missed outage can cost more than a whole year of paid monitoring.
How to set up uptime monitoring in 5 minutes
- Pick a tool from the list above.
- Add your homepage as your first monitor. Most tools only need the web address.
- Add your most important pages: contact form, booking page, checkout, or login.
- Turn on SSL and domain expiry alerts if the tool offers them.
- Make sure alerts go to an email you check daily, not an old inbox nobody reads.
Before you start, you can see whether a site is up right now with our free Website Down Checker. It checks the site from our server and explains any problem in plain English.
