How to Monitor Your Website Uptime for Free
October 12, 2026 · 6 min read
Why uptime is worth watching at all
A site that is unreachable for ten minutes a month is up 99.98% of the time, and still costs you a day of customers who could not check out, open your API, or read your status page. Uptime monitoring exists to find the minutes you are not looking, so a 99.98% month stays that way instead of quietly becoming a 98% one.
What "continuous" monitoring actually means
A manual check only tells you about the moment you remembered to run it. Continuous monitoring is a request hitting your URL on a schedule, day and night, from a server that is not on your network. When that request fails twice in a row, a real monitor opens an incident and notifies you, instead of waiting for a customer to email you about an outage you might never have seen.
The honest part: free plans are limits, not marketing
Every uptime service has a free tier, and they all work the same way: a small number of monitors, slower check intervals, a narrower alert setup. That is fine. The point of free is to prove the loop works - monitor, incident, alert - before you pay for faster checks or more sites. A free plan that quietly caps alerts at email-only is still a complete safety net for a side project.
What to check first, before adding anything
Start with the things that lose you credibility when they break: your main website, your API, sign-in if you have it, and your payment flow. One monitor per service, a 200 status as the expected result, and a two-failure threshold so a single flaky request does not page you at 3 a.m.
How to start for free in about five minutes
Create an account, paste a URL, pick a check interval, and add an email address to notify. UptimeCadet's free plan gives you one monitor checked every five minutes with email alerts, an SSL expiry warning, and a public status page. That is a complete, honest free tier - not a trial that shuts off after a week.
When it is worth paying
Upgrade when the free setup stops being enough: you want checks every sixty seconds instead of every five minutes, alerts in Slack, Discord or Telegram instead of one inbox, more monitors, or a status page people depend on. Until then, free monitoring beats no monitoring by a wide margin, and it costs you nothing but signing up.
