Best uptime monitoring tools

Every tool here will tell you a URL stopped answering. The differences are price, how many checks you need, whether you want to self-host, and how good the status page is when something breaks. This list is ordered for the common case — one product, a small team — not for an enterprise with a monitoring budget line.

1. 1. GreenCrew

   Uptime checker · Hosted

   The smallest honest option if you have one site or API and want a status page at greencrew.space/yourhost that you can overwrite when a green check is lying.

   Pricing: Free while we keep it simple.

2. 2. UptimeRobot

   Uptime checker · Hosted

   The volume default: a free tier people actually use, plus keyword and heartbeat checks once you pay. Start here if you are watching many URLs.

   Pricing: Free tier, then inexpensive paid plans as monitor count grows.

3. 3. StatusCake

   Uptime checker · Hosted

   Uptime with SSL, DNS, and domain-expiry tests built in — the checker that takes the boring, silent failures seriously.

   Pricing: Freemium uptime plans. SSL and domain tests sit beside HTTP, not behind APM.

4. 4. HetrixTools

   Uptime checker · Hosted

   Uptime plus blacklist monitoring and white-label status pages. The pick if you watch other people’s sites, not just your own.

   Pricing: Inexpensive hosted plans. Often pitched to hosters and agencies, not only indie apps.

5. 5. Uptime Kuma

   Uptime checker (self-hosted) · Self-hosted

   Free, open-source, and yours to run in Docker — as long as you accept the monitor shares fate with the box you put it on.

   Pricing: Free software. You pay the VPS, the backups, and the time.
