comparing self-hosted
Uptime Kuma vs OneUptime: one tool, or the whole stack?
These two tools are not the same size, so comparing them feature by feature helps little. Uptime Kuma is a monitor. OneUptime is a platform that wants to replace most of your monitoring tools. Pick the wrong one and it will be too small for you, or far too big.

The main difference
Size, mostly. Uptime Kuma checks uptime, and it does that in one container. OneUptime says clearly that it wants to replace many paid tools at once. It does uptime monitoring in place of Pingdom or UptimeRobot, and status pages with subscribers in place of Statuspage. It handles on-call schedules and escalation in place of PagerDuty or Opsgenie. It also covers incident management, APM and metrics in place of Datadog or New Relic, plus log management and error tracking in place of Sentry. All of it is Apache 2.0 and free to self-host.
What OneUptime does better
Everything that happens after a check fails. It has real teams and on-call schedules with escalation rules. It sends alerts by SMS, phone call, push and Slack. It handles the whole incident, from the first report to the post-mortem. Its status pages take subscribers and can be public or private. It also collects traces, dashboards, logs and stack traces, so the tool that wakes you up can also show you the cause. It has a Helm chart for production and a docker compose install for smaller setups.
What Uptime Kuma does better
Focus, and the checks. Kuma supports 31 monitor types from the start, including databases, MQTT, SNMP and a real Chromium browser check. It sends alerts to 94 services, and version 2.x checks every second. You install it as one container in about five minutes, and it has by far the biggest community of these tools. If you only need uptime checks, OneUptime is a very large platform to run for one job.
The limits of both
OneUptime's size is also its price. It runs as many services, and it publishes sizing guides because you need them. Choosing it changes your whole setup, so it is harder to leave than a single monitor. Uptime Kuma has the usual limits. It has one shared login and no user roles. It has no official REST API to manage monitors, and no Terraform provider. And it sees your service from the server where you installed it, unless you add its Globalping monitor type, which borrows community-hosted probes you do not control.
Where Uptimepage fits
Most teams that grow past Kuma do not want a full observability platform. They want the two or three things Kuma lacks: an account for each teammate, a status page customers can subscribe to, and monitoring settings kept in version control. Uptimepage adds those things and little else, on purpose. It checks every 60 seconds over HTTP, TCP, DNS, TLS and ping. It has organizations with user roles, a Terraform provider, a REST API and an MCP server. Its probes run in several regions, and you can run your own. Its status page is branded, and customers can subscribe by email or webhook. It is one binary. Host it free, or self-host it under AGPL.
