The short version

  • Each has a real cost: Netdata the dashboard interface is under a restrictive Netdata licence rather than GPL and is served from Netdata infrastructure by default, so the deployment is not fully self-contained without extra configuration.; VictoriaMetrics promQL compatibility is very close but not identical, and MetricsQL extensions do not port back
  • They diverge on capability: Netdata covers Per-second collection, VictoriaMetrics covers PromQL compatible.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Netdata

  • The dashboard interface is under a restrictive Netdata licence rather than GPL and is served from Netdata infrastructure by default, so the deployment is not fully self-contained without extra configuration.
  • Retention is limited by disk on each node unless you build and maintain a parent tier, which makes it a poor archive for year-over-year capacity planning.
  • Per-second collection consumes noticeable CPU and memory on small or heavily loaded nodes, and on constrained edge hardware the monitoring becomes part of the problem.
  • Default alerting is generous and fires on conditions many teams consider normal, so the first weeks involve pruning alarms rather than responding to them.
  • Fleet-level features that make it usable across hundreds of nodes sit in Netdata Cloud, so the free agent alone leaves you visiting individual node dashboards.

VictoriaMetrics

  • PromQL compatibility is very close but not identical, and MetricsQL extensions do not port back
  • Smaller community than Prometheus, so fewer guides and third-party integrations
  • The clustered version has meaningfully more moving parts than the single binary suggests
  • Some enterprise features sit outside the open-source offering

Does Netdata or VictoriaMetrics run on more platforms?
Netdata runs on Linux, macOS, FreeBSD, Docker, Kubernetes, Windows. VictoriaMetrics runs on Linux, Docker, Kubernetes, Self-hosted.
Can I use Netdata for free?
Both have a free tier, so you can try either at no cost before committing.
What is Netdata best used for?
Netdata is most often used for diagnosing a short-lived performance incident where one-minute averages hide the spike entirely, kubernetes clusters where per-series billing from a hosted vendor has become the largest observability cost, adding dense host visibility to an estate that already has prometheus for application metrics, small teams with no monitoring engineer who need working dashboards on the day of installation. Of those, diagnosing a short-lived performance incident where one-minute averages hide the spike entirely and kubernetes clusters where per-series billing from a hosted vendor has become the largest observability cost are not what VictoriaMetrics is typically brought in for.

Answered from the vendors’ own pages

Netdata: Is Netdata fully open source?

The agent is GPLv3. The current dashboard interface is under a separate restrictive licence, so the complete product is open core rather than open source.

VictoriaMetrics: Is VictoriaMetrics free?

The open-source version is free with no data limits. An enterprise edition and cloud service are paid.

Netdata: Can it run without any connection to Netdata Cloud?

Yes, agents work standalone and dashboards can be served locally, but you lose fleet-wide views and need to configure local interface serving deliberately.

VictoriaMetrics: Does it replace Prometheus?

It can, but most teams keep Prometheus for scraping and use VictoriaMetrics as the long-term store behind it.

Netdata: Does it replace Prometheus?

For host and container infrastructure metrics it often does. For custom application metrics with an existing exporter ecosystem and long retention, most teams keep both.

VictoriaMetrics: Is PromQL fully supported?

Very nearly. It implements PromQL and extends it with MetricsQL, though a small number of edge-case behaviours differ.
