Uptime Kuma Alternatives for Mac (2026): Uptime Monitoring Without a Server

By Paul Snyman · Published September 1, 2026 · 6 min read

Uptime Kuma is one of the best pieces of free software in its category. The reason people look for alternatives is almost never the software. It is that self-hosting means a machine, a container, updates, and a thing that breaks silently at the worst moment.

Full disclosure: I build PingKit Agent, so weigh the recommendation accordingly. The limits section is not padding, and there is a whole category of Mac network tool below that PingKit deliberately is not.

The Real Question: Where Does the Check Run?

An uptime monitor is only as reliable as the thing performing the check. This is the decision that matters:

The middle row is the trap. Running an uptime monitor on a laptop tells you the site was up whenever you happened to be at your desk.

How PingKit's Uptime Watch Works

Checks run server-side on a scheduled job, not on your Mac or iPhone. The app adds and views targets; it does not perform the probes. So your Mac can sleep, your phone can be off, and the checks continue.

Being precise about the mechanics, because vagueness here is how people get let down:

• Every five minutes with Guardian, hourly on the free tier. The cadence belongs to the tier, not a configurable interval.
• Website or port. A target is an HTTP(S) URL, or with Guardian a TCP port on a public host. Any final status from 200 to 399 counts as up.
• Optional content checks with Guardian. A website target can require a keyword on the page (case-sensitive, exact text) or an exact status code.
• Targets and history: one target and 7 days of history on the free tier; ten targets and 30 days with Guardian, each with an hourly response-time chart.
• How you are told. A Mac cannot receive a push. With Guardian the Agent reads its targets every five minutes while it runs and shows a notification on the Mac when one goes down or recovers; a target added on the iPhone gets a push there. Guardian Plus also sends every alert by email and to a webhook, which reach you while the Mac sleeps.

Where Uptime Kuma Wins, Clearly

If you need sub-minute checks, ping or DNS monitors, dozens of notification services or a public status page, Uptime Kuma is simply the better tool and you should run it. Five-minute checks suit "tell me soon after my site goes down", not "page me within a minute".

What Comes With It

Uptime Watch is one pane of the Agent rather than a standalone product, so it sits alongside continuous device discovery, internet up/down alerting, scheduled speed tests and TLS certificate expiry monitoring. If you want an uptime monitor and nothing else, a dedicated service is a cleaner fit.

Honest Limits

• Five minutes at best (hourly on the free tier), and HTTP or TCP only, as above. This is the main gap.
• Public targets only. The checks run on Cloudflare, so they cannot reach anything with a private address.
• No status pages, and no integrations beyond email and one webhook, both of which need Guardian Plus ($4.99/mo on Mac).
• The apps do not perform the checks, so behaviour does not change if you close them.
• macOS 15 or later for the Agent.

Frequently Asked Questions

Can I run Uptime Kuma on my Mac?

You can, but it stops when the Mac sleeps, which undermines the purpose. Uptime Kuma is best on something that never sleeps, such as a VPS, a NAS or a Raspberry Pi.

What is a good Uptime Kuma alternative without self-hosting?

A hosted check. PingKit's Uptime Watch runs its checks server-side, so nothing depends on your devices being awake: one URL hourly for free, or ten website or TCP port targets every five minutes with Guardian. It is far simpler than Uptime Kuma: no one-minute checks, no ping or DNS monitors and no status pages, and alerts by email or to a webhook need Guardian Plus.

Does PingKit check uptime from my Mac or iPhone?

Neither. Checks run on a scheduled server-side job. The apps add and view targets only, so your Mac can sleep and your phone can be off without affecting the monitoring.

How often does PingKit check a site?

Every five minutes with Guardian and once an hour on the free tier. The cadence belongs to the tier and is not user-configurable. If you need checks every minute, use a dedicated uptime service or self-host Uptime Kuma.

How many sites can I monitor?

One on the free tier, checked hourly, and ten with a Guardian subscription, checked every five minutes. Guardian is $2.99 per month or $24.99 per year on the Mac.
