HetrixTools vs Uptime Kuma

Kuma will do more protocols if you run the box. HetrixTools will do blacklists and white-label if you pay the host. Both can look like “serious uptime” on a feature list. Only one is someone else’s uptime.

Side by side

Topic	HetrixTools	Uptime Kuma
Best for	Sysadmins and hosters who want uptime plus blacklist monitoring, or a white-label status page for clients.	People who already self-host, want many monitor types, and accept that the checker is another box they own.
Not for	Teams buying APM, or founders who wanted a consumer-simple page without blacklist and server-agent surface area.	Founders who did not want another container, or who need a status URL that stays up when their VPS does not.
Hosting	Hosted	Self-hosted
What it checks	Uptime, SSL, blacklists, and an optional Windows/Linux server agent. Maintenance windows are a first-class idea.	HTTP, keyword, TCP, DNS, Docker, push/heartbeats, and more — depending on how you configure it.
Status page	White-label public status pages — a real differentiator if you monitor other people’s sites.	You can expose a status page from the same instance. It lives where you deployed it.
Alerts	Email, SMS, webhooks, and phone-call notifications on newer plans.	Huge list of notification backends if you configure them.
Complexity	Simple to moderate	Simple software, operationally yours.
Pricing shape	Inexpensive hosted plans. Often pitched to hosters and agencies, not only indie apps.	Free software. You pay the VPS, the backups, and the time.

What HetrixTools is

Uptime, blacklists, and server agents, with white-label status pages for people who resell monitoring. Sysadmins and hosters who want uptime plus blacklist monitoring, or a white-label status page for clients. Teams buying APM, or founders who wanted a consumer-simple page without blacklist and server-agent surface area.

What Uptime Kuma is

The open-source Docker monitor you run yourself. Free, flexible, and yours to keep online. People who already self-host, want many monitor types, and accept that the checker is another box they own. Founders who did not want another container, or who need a status URL that stays up when their VPS does not.

The actual split

HetrixTools is hosted. Uptime Kuma is self-hosted. That is the first fork — who owns the checker when your own network is the thing on fire.

Who should pick which

HetrixTools: Sysadmins and hosters who want uptime plus blacklist monitoring, or a white-label status page for clients.
Uptime Kuma: People who already self-host, want many monitor types, and accept that the checker is another box they own.
