Yes, Uptime Kuma is free and open-source (MIT license) with no paid tier. You run it yourself, typically via Docker on a VPS, home server, or NAS, which means you're paying for and maintaining whatever it runs on, and you own that uptime, too.

Is PingKit's uptime monitoring free?

PingKit's on-demand tools are free. Uptime Watch, continuous URL monitoring with push alerts, requires Guardian at $2.99/month, which also includes Scheduled Speed Tests and the Mac Agent.

Does Uptime Kuma have a mobile app?

Not an official first-party one. Its web dashboard is responsive and usable from a phone browser, and a handful of unofficial third-party mobile clients exist, but there's no app maintained by the Uptime Kuma project itself. PingKit's app is first-party and native on iPhone and Mac.

Which is better for monitoring a home server?

Depends on where you'd run Uptime Kuma. If it runs on the same server or network it's monitoring, an outage there can silently take your monitoring down with it. Hosted elsewhere (a cheap VPS), that risk goes away but adds ongoing cost and setup. PingKit's Uptime Watch has no server to fail because there isn't one.

PingKit vs Uptime Kuma

A different kind of comparison than PingKit's other uptime-monitoring match-ups: Uptime Kuma isn't a company selling a plan, it's free, open-source software you run yourself. The trade-off isn't features versus price, it's capability versus maintenance.

Uptime Kuma is one of the most popular self-hosted monitoring tools on GitHub (84,000+ stars as of 2026), typically run in Docker on a home server, NAS, or VPS. PingKit's Uptime Watch is one feature inside a free iPhone/Mac network toolkit. We make PingKit, so weigh that accordingly, but every claim below is checked against Uptime Kuma's own documentation and PingKit's shipped feature set.

Where Uptime Kuma Wins

If you're comfortable running a Docker container and keeping it patched, Uptime Kuma is simply more capable: unlimited monitors, checks as frequent as every 20 seconds, six monitor types instead of one, a free public status page, and 90+ notification integrations that put PingKit's single push-alert channel to shame. It's free software with no subscription, ever, and your monitoring data lives entirely on infrastructure you control. For a homelab or self-hosting enthusiast who already runs other services, adding one more container is a small ask for a lot of capability.

Where PingKit Wins

The thing Uptime Kuma doesn't solve is who monitors the monitor. If you run it on the same home server or network it's watching, an outage there can silently take your alerting down with it, the exact failure you set it up to catch. Hosting it separately (a cheap VPS) fixes that, but now you're paying for and maintaining a second always-on service, plus keeping it updated for security patches, indefinitely. PingKit's Uptime Watch has none of that: no server to provision, patch, or lose track of, just a toggle in an app you already have installed, and it sits alongside LAN Scanner, Wake-on-LAN, Port Scanner, and 15 more tools most self-hosters would reach for anyway.

The honest trade-off: hourly checks mean an outage could run up to an hour before Uptime Watch notices, versus Uptime Kuma's 20-second interval. If minutes matter, or you want status pages and rich integrations, Uptime Kuma is the stronger tool, and the "maintenance cost" of running it is genuinely small for anyone already comfortable with Docker.

Which Should You Choose?

Already self-hosting other services, comfortable with Docker, want maximum capability for free: Uptime Kuma.
Want to watch a home server/NAS/side project with zero setup and nothing new to maintain: Uptime Watch is one toggle, not a second service to run.
Want the rest of PingKit's toolkit regardless: Download PingKit free, Uptime Watch is optional, the other 18 tools aren't gated.
