The short version

  • Only Netdata has a free tier, so it costs nothing to try first.
  • 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.; Sysdig custom pricing requires sales contact, difficult to compare costs
  • They diverge on capability: Netdata covers Per-second collection, Sysdig covers Real-time threat detection and response.
  • 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.

Sysdig

  • Custom pricing requires sales contact, difficult to compare costs
  • No published pricing tiers or calculator available
  • Primarily focused on cloud-native environments
  • Requires integration with existing SIEM or monitoring tools for full visibility
  • Steep learning curve for runtime security concepts

Questions people ask

Is Netdata or Sysdig better?
Neither clearly leads. Netdata starts at Free and Sysdig at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Netdata or Sysdig?
Netdata has a free tier; the other does not. Paid plans start at Free for Netdata and On request for Sysdig.
Does Netdata or Sysdig run on more platforms?
Netdata runs on Linux, macOS, FreeBSD, Docker, Kubernetes, Windows. Sysdig runs on Kubernetes, Docker, AWS, GCP, Azure, Cloud-native.
Can I use Netdata for free?
Yes. Netdata has a free tier, so you can try it without paying. Sysdig starts at On request.
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 Sysdig is typically brought in for.
What can Netdata do that Sysdig cannot?
Netdata covers Per-second collection, Zero-configuration discovery, Edge machine learning, Tiered database engine. Sysdig covers Real-time threat detection and response, Runtime intelligence, AI-powered security agents, Vulnerability management.

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.

Sysdig: How does Sysdig achieve real-time threat detection?

Sysdig uses runtime intelligence with kernel-level system visibility, capturing live system calls to detect threats at machine speed, typically within 2 seconds.

Source
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.

Sysdig: What is runtime intelligence and how does it differ from configuration-based security?

Runtime intelligence reveals what is actually executing in cloud environments through kernel-level visibility, rather than relying on theoretical risks from configuration analysis alone.

Source
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.

Sysdig: What cloud platforms does Sysdig support?

Sysdig supports AWS, GCP, Azure, and IBM Cloud with multiple regional data centers across US, EU, and other regions.

Source
Sysdig: Does Sysdig integrate with existing security tools?

Yes, Sysdig integrates with existing SIEM and monitoring tools to provide unified security visibility across cloud infrastructure.
