Uptime Kuma vs UptimeRobot · The part the comparison tables leave out
Uptime Kuma is free.
Running it isn't.
Self-hosting looks free because the software costs nothing. But someone on your team pays the bill in hours: patching the server, wiring up every alert channel, and covering for the one blind spot self-hosting can't fix. See what that actually costs your team per year.

Show what maintenance usually includesHide maintenance checklist
- A separate server to run it on, from ~$5/mo
- Docker, Node.js, and a process manager to keep it alive
- SSL certificates, handled yourself, if you want the dashboard over HTTPS
- Regular database backups — Kuma stores everything locally
- Software updates every time a new version ships
- When something breaks, you're the support team
People underestimate this — open the checklist below.
80% of paying teams run 2+ channels. Each one is a separate integration to wire and keep working.

What's inside the Uptime Kuma number
| Maintenance labor | $3,600 |
| Alert channel upkeep | $450 |
| Hosting | $72 |
The number teams underestimate isn't hosting. It's how they actually monitor.
Serious monitoring is multi-monitor and multi-channel. Both cost labor when you run the box yourself. Numbers below are from UptimeRobot's paying customer segment, not the industry at large.
31
Average monitors per paying team
Median is 10. Every monitor goes dark if the self-hosted box does.
26%
Multi-type coverage on one domain
HTTP + keyword + ping + port. Each layer is setup work you own.
80%
Paying teams use 2+ alert channels
In Uptime Kuma, every channel is a separate integration. In UptimeRobot they're built in.
The blind spot self-hosting can't fix
Uptime Kuma runs on your infrastructure. When your network, power, or region goes down, the outage takes your app and your monitor with it — so the alert never fires. UptimeRobot checks from multiple locations outside your stack, and re-checks from other regions before alerting.
Alerts your team stops trusting
Self-hosted monitoring checks from one place, so every hiccup looks like an outage. After enough false pages, people treat alerts as noise — and the next real outage gets missed. UptimeRobot re-checks from a different region before it pages anyone.
This isn't a knock on open source. If you run a handful of monitors and have someone who enjoys maintaining the box, Kuma is a fine choice — the math above is for the point where that stops being true.
Monitoring you set up and forget.
Managed monitoring for less than the hours you'd spend maintaining the box.
Alerts built in
Email, SMS, Slack, voice — without wiring and babysitting each channel yourself.
Set up and forget
No Docker, SSL renewals, or weekend patching. Monitoring that stays off your sprint board.
Team from $35/mo
Shared access on annual Team billing — usually cheaper than the hours you'd spend on the box.
Methodology & sources
- Usage baselines (31 avg monitors, 26% multi-type, 80% multi-channel) come from activated UptimeRobot accounts in the paying segment only — not the full 3.7M+ user base, and not an industry-wide claim.
- Labor cost = maintenance hours × hourly rate × 12. The monitors slider mainly picks which UptimeRobot plan we compare against — it does not scale the labor total by itself. If you run many monitors, raise the maintenance-hours slider to match your reality.
- Engineer hourly rate default $75 is a labelled industry-standard fully-loaded estimate, not a fixed figure — move the slider to match your team.
- Alert channel upkeep estimates ~2 hrs one-time setup plus light upkeep per channel, amortized across the year at your rate.
- UptimeRobot pricing is the current USD list price, billed annually — the plan ladder picks whichever tier fits your monitor count. Your region's checkout price may differ.
- Hosting figures are typical VPS list prices; "Spare box" assumes no incremental hosting spend (labor still applies).
Frequently asked questions.
The software is open source and free to download. Running it is not: you still pay for a server (or the opportunity cost of a spare box), engineer time for updates and breakage, and the setup/upkeep of every alert channel. The calculator makes those costs visible.
Team is our most popular paid plan for small teams that need shared access. In this draft we price Team at $35/mo billed annually. The ladder is TCO-oriented: Solo for ≤10 monitors, then Team up to 100 (we skip Solo 50 on purpose — shared access is usually why teams leave Solo), then Scale, then Enterprise above 500.
If your downtime monitor runs on the same server, VPS provider, or network as the service it watches, an outage can take down both the app and the alerter. Nobody gets notified. UptimeRobot checks from multiple locations outside your stack so that failure mode does not apply.
If you run a handful of monitors, have someone who enjoys maintaining the box, and accept the single-location blind spot, Uptime Kuma is a fine choice. The calculator is aimed at the point where maintenance hours, multi-channel coverage, and that blind spot make managed monitoring cheaper and safer.
No. Monitor counts, multi-type usage, and multi-channel rates come from activated UptimeRobot accounts in the paying segment. They describe how our customers actually monitor — useful defaults, not a claim about the whole industry.
Self-hosted cost = maintenance labor + alert-channel upkeep + hosting, all annualized. Labor is hours × hourly rate × 12 (default 4 hrs/month). Alert channels assume about 2 hours of setup/upkeep per channel per year at your rate. Hosting uses typical VPS list prices; “Spare box” is $0 hosting with the same-infrastructure blind spot called out. The monitors slider mainly picks the UptimeRobot plan on the other side of the chart (annual USD list price; Team at $35/mo in this draft) — it does not inflate the self-hosted labor total by itself. If your team runs many more monitors than the labor estimate implies, raise the maintenance-hours slider to match.
