Kitaso vs Datadog: the arithmetic for five servers
Datadog is priced per host per month for teams running hundreds of them. Kitaso is $39 once. Here is what the difference buys, and what it does not.
Datadog is an observability platform for teams running hundreds of hosts who need metrics, traces and logs correlated in one place. Kitaso is a Mac app that charts CPU, memory, disk, load and Docker stats for the Linux boxes you own. They are not competitors at Datadog's scale. They overlap at the small end, where both can do the job and the price difference is three orders of magnitude.
The pricing
Every Datadog figure here comes from datadoghq.com/pricing, checked on 4 September 2026. Vendor pricing moves, so check it again before acting on the arithmetic.
| Kitaso | Datadog | |
|---|---|---|
| Model | One-time purchase | Per-host, per-month subscription |
| Infrastructure | $39 once (1 year of updates included), unlimited servers | $15/host/month (annual), $18 on-demand |
| APM | Not offered | +$31/host/month (annual) |
| On each server | An optional scheduled collector writing to SQLite | A resident agent reporting to the cloud |
| Free tier | 2 servers, forever, no account | Up to 5 hosts, 1 day of retention |
| Where your data lives | Your Mac | Datadog's cloud |
Five servers on the annual Infrastructure plan is 5 × $15: $75 a month, $900 a year. Add APM and it is around $230 a month, roughly $2,760 a year, every year. Infrastructure billing is high-water mark — hosts are metered hourly and the 99th percentile is billed, so a brief spike is forgiven while a sustained busy week sets the bill for the whole month.
Kitaso is $39 once, with a year of updates included. Two servers are free with no account, so it can be tried on real boxes before anything is paid.
What the difference buys
Datadog: distributed tracing, log aggregation, hundreds of integrations, anomaly detection, retention measured in months, and dashboards a whole on-call rotation reads from any device.
Kitaso: CPU, memory, disk, load and Docker stats, per server, charted on your Mac, with threshold alerts. That is the complete list. No tracing, no log aggregation, no shared dashboard, no cloud.
At a few hundred hosts, Datadog earns its price and Kitaso cannot do the job at all. At five, most of what the bill covers is capability that never gets opened.
What five servers actually need
Is CPU pegged, is memory running out, is a disk filling up, are the containers running, was this happening yesterday too, and will you hear about it before a user emails.
Kitaso answers those six questions and stops there. The optional collector on each box keeps gathering while the Mac sleeps, so an overnight incident is on the chart in the morning. That is history rather than paging: live alerts fire from the Mac, while it is awake.
If a Datadog quote is sitting in an inbox and the fleet is five servers, the small thing is worth trying first. Two servers free at kitaso.app.
