Why Exit1.dev Stands Out

Exit1.dev's free tier gets you started fast, and the Nano plan ($3/month) delivers unlimited monitors with 1-minute checks.

How to Pick the Right Tool

For most, Exit1.dev's free tier is a great starting point, with an affordable upgrade path when you need more.

Judge any “free” plan by the constraints they hide. Check how many sites you can watch, how often checks run, and whether alerts actually reach the team before users do. Dig into export options and API limits too—some vendors lock your data behind paywalls. If you need a status page or webhooks, make sure they aren't premium add-ons. A tool is only free if it lets you run real monitoring without nickeling you for basics.

Maximize Your Monitoring

Focus on critical paths. Use webhooks for auto-fixes.

The Future: Affordable Monitoring Wins

Generous free tiers plus affordable paid plans are the way forward.

FAQs

Are free uptime monitors reliable enough for production?

Most handle basic checks fine, but watch for slow intervals or weak alerting that delay response times.

Can I use multiple free tools together?

Sure, stack them if you don’t mind duplicate alerts. Just centralize notifications so you can sleep.

What happens when my site outgrows a free tier?

Upgrade to a paid plan. Exit1.dev’s Nano plan ($3/month) gives you unlimited monitors with 1-minute checks.

Conclusion

Free uptime monitoring only matters if it keeps you in the loop. Exit1.dev's free tier gives you 10 monitors to get started, and the Nano plan ($3/month) removes all limits.
