Best VPS for Monitoring & Uptime in 2026
Updated Oct 2026 · 8 plans compared
A monitoring stack — Uptime Kuma, Grafana, Netdata, or Prometheus — is exactly the kind of workload a cheap VPS was made for: always-on, light, and far more valuable for its uptime than its specs. These boxes run a full observability stack while leaving RAM to spare.
- Uptime is the product — pick a provider with a solid track record, since this is the box that tells you when everything else is down.
- Enough RAM to run a few collectors plus their time-series data; 2 GB covers Uptime Kuma, Grafana, and a Prometheus or Netdata agent comfortably.
- Fast disk for the metrics database as history grows.
- A region near your other servers, so latency checks reflect reality rather than geography.
The picks
Hourly billing is perfect for a disposable probe or a second monitoring instance in another region, and custom sizing fits a growing metrics database.
A CPX22 (2 vCPU / 4 GB) runs Uptime Kuma, Grafana, and a metrics backend at a few percent utilization, with generous traffic for frequent checks.
The smoothest setup of the group with one-click monitoring images and the clearest docs — worth the premium if you'd rather not configure from scratch.
The most RAM and disk per dollar — 8 GB NVMe for $4.95 leaves huge headroom for long retention on your metrics database.

Common questions
How much RAM does a monitoring stack need?
Uptime Kuma runs in about 512 MB and Grafana in 1 GB; a Prometheus or Netdata agent adds a few hundred MB more. 2 GB comfortably runs the whole set, and 4 GB leaves room for long metric retention.
What's the best uptime monitor to self-host?
Uptime Kuma is the crowd favorite — one container, zero configuration, HTTP/TCP/ping checks, and notifications to nearly anything. Grafana is the standard for dashboards once you outgrow simple status pages.
Can I monitor my other servers from one box?
Yes — that's the normal setup. One VPS runs the monitors and dashboards while agents on your other servers ship metrics to it. Just make sure the monitoring box isn't on the same provider's network as everything you're watching.
