UptimeRobot alternatives, compared plainly.
UptimeRobot's free plan checks 50 sites every 5 minutes, which is hard to beat if you only need to know when a site is down. People usually look elsewhere for one of four reasons: Slack or Telegram alerts without paying, page speed checks, checks that scheduled jobs (cron jobs, backups) ran, or running it on their own server.

Up isn't the same as fast
Why people switch from UptimeRobot
On the free plan, UptimeRobot doesn't send alerts to Slack or Telegram, doesn't check that scheduled jobs ran, and doesn't warn you when responses get slow. All three start on its Solo plan.
UptimeRobot also tells you whether your site answers, not how fast your pages load for visitors. If your site is up but slow, a separate page speed tool is what catches it.
We make nimo
Where nimo fits
ChatGPT or ClaudeWe make nimo, so weigh this part accordingly. nimo is for people who want one place to hear that their site is down, that an important page got slower, or that a backup didn't run, without stitching three tools together.
It checks that your site loads every 5 minutes and sends alerts to Slack or Telegram. It checks how fast your key pages load weekly on Pro or daily on Business; when they get slower, it shows which ones and by how much, and suggests what to look at first. You can connect it to ChatGPT or Claude and ask "is my site up?" or "why did my homepage get slower?".
If you only need up/down alerts, UptimeRobot's free plan or Uptime Kuma costs less.
Common questions
Quick answers
Is UptimeRobot still free?
Yes. As of October 9, 2026, its free plan covers 50 monitors checked every 5 minutes. Slack and Telegram alerts, scheduled-job checks, and slow-response alerts start on the Solo plan at $13 a month.
What's the best free alternative to UptimeRobot?
Uptime Kuma if you can run your own server: it's free and alerts to Slack, Telegram, and more. Better Stack's free plan suits personal projects and includes Slack alerts and scheduled-job checks. StatusCake's free plan adds a daily page speed test.
Which alternatives also check page speed?
StatusCake and Pingdom measure page load time, size, and requests. nimo checks your key pages weekly on Pro or daily on Business, shows which got slower, and suggests what to look at first.
Does UptimeRobot work with ChatGPT or Claude?
Yes. UptimeRobot, Better Stack, Cronitor, and nimo all offer an official connection (an MCP server) that ChatGPT, Claude, and other assistants can use to read your monitors.
How do I know if a cron job or backup didn't run?
Have the job check in: add one line that visits a web address when the job finishes, and you get an alert if that visit doesn't arrive on time. Healthchecks.io, Cronitor, Better Stack, Uptime Kuma, and nimo all do this, and so does UptimeRobot on paid plans.
