Sematext vs Uptime Kuma

Sematext Logs, metrics, tracing, and experience monitoring — an observability suite that also pings URLs. Uptime Kuma The open-source Docker monitor you run yourself. Free, flexible, and yours to keep online. Sematext 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. If you only needed a public status page and a health check, neither may be the smallest tool — GreenCrew is built for that job.

Side by side

Topic	Sematext	Uptime Kuma
Best for	Teams that want ELK-shaped logs, APM, and synthetics without signing a Datadog-sized contract.	People who already self-host, want many monitor types, and accept that the checker is another box they own.
Not for	A founder whose actual need is “tell me if the site is up” and a link for customers.	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	Synthetics, RUM, infrastructure metrics, logs, and tracing. HTTP uptime is one tile on a larger board.	HTTP, keyword, TCP, DNS, Docker, push/heartbeats, and more — depending on how you configure it.
Status page	Not the centre of the product — observability first, status second.	You can expose a status page from the same instance. It lives where you deployed it.
Alerts	Threshold and anomaly alerts across logs, metrics, and synthetics.	Huge list of notification backends if you configure them.
Complexity	Heavy	Simple software, operationally yours.
Pricing shape	Usage-based observability pricing. You pay for data, not for one URL.	Free software. You pay the VPS, the backups, and the time.

What Sematext is

Logs, metrics, tracing, and experience monitoring — an observability suite that also pings URLs. Teams that want ELK-shaped logs, APM, and synthetics without signing a Datadog-sized contract. A founder whose actual need is “tell me if the site is up” and a link for customers.

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

Sematext 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

Sematext: Teams that want ELK-shaped logs, APM, and synthetics without signing a Datadog-sized contract.
Uptime Kuma: People who already self-host, want many monitor types, and accept that the checker is another box they own.
