The short version

  • Each has a real cost: NetBird self hosting requires an identity provider, and the bundled option adds a second unfamiliar service to operate, so the free path costs more administrative time than the docker compose file suggests.; 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.
  • They diverge on capability: NetBird covers WireGuard data plane, Netdata covers Per-second collection.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

NetBird

  • Self hosting requires an identity provider, and the bundled option adds a second unfamiliar service to operate, so the free path costs more administrative time than the docker compose file suggests.
  • Peers that cannot connect directly fall back to relays, and on a self hosted deployment that relay bandwidth is your cost and your bottleneck rather than an included service.
  • If the self hosted management server is down, existing tunnels keep working but no new peer can join and no policy change takes effect, which makes it a component that needs its own availability plan.
  • Some capabilities aimed at larger organisations sit in the paid cloud tiers, so a self hosted deployment does not have exactly the same feature set as the hosted one.
  • The project moves quickly and configuration and deployment layouts have changed between versions, so self hosted upgrades need reading release notes rather than pulling a new image.

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.

Can I use NetBird for free?
Both have a free tier, so you can try either at no cost before committing.
What is NetBird best used for?
NetBird is most often used for replacing a vpn concentrator that backhauls all traffic through one office, giving contractors access to two specific services rather than to a subnet, connecting workloads across several clouds without peering vpcs or managing route tables, meeting a requirement that the network control plane must run inside your own infrastructure. Of those, replacing a vpn concentrator that backhauls all traffic through one office and giving contractors access to two specific services rather than to a subnet are not what Netdata is typically brought in for.
What can NetBird do that Netdata cannot?
NetBird covers WireGuard data plane, NAT traversal with relay fallback, Identity based access control, Network routes. Netdata covers Per-second collection, Zero-configuration discovery, Edge machine learning, Tiered database engine.

Answered from the vendors’ own pages

NetBird: Is the self hosted version crippled?

No. The management, signal and relay components are all open source and the network works without any NetBird operated service.

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.

NetBird: How does it differ from Tailscale?

Similar model and similar clients, but Tailscale keeps its coordination server proprietary. NetBird publishes its whole control plane, which is the reason most self hosters choose it.

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.

NetBird: Do I need to open firewall ports?

No inbound ports are required. Peers make outbound connections to the signal service and to each other.

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.

NetBird: What happens to traffic if NetBird the company disappears?

On a self hosted deployment, nothing, since you run every component. On the cloud service you would need to stand up your own control plane and re-enrol peers.
