The short version

  • Only NetBird has a free tier, so it costs nothing to try first.
  • 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.; PRTG Network Monitor licensing by sensor rather than device means the real cost per device is unpredictable until sensor density is measured; a small network of complex devices can need a much larger tier than device count alone suggests
  • They diverge on capability: NetBird covers WireGuard data plane, PRTG Network Monitor covers Sensor-based monitoring.
  • Prices and features above were last checked on 1 September 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.

PRTG Network Monitor

  • Licensing by sensor rather than device means the real cost per device is unpredictable until sensor density is measured; a small network of complex devices can need a much larger tier than device count alone suggests
  • Different PRTG licence sizes cannot be combined on one server, so outgrowing a tier means a step change to the next tier rather than a smooth incremental add
  • It requires a Windows server for on-premises deployment, which is an added infrastructure and patching burden compared with a Linux-native open source alternative
  • Pricing is materially higher than open source options like Icinga or LibreNMS for comparable core monitoring capability, and the premium is for polish and support rather than unique functionality
  • The free tier (100 sensors) is limited enough that most real deployments quickly need a paid tier, so it functions more as a trial than a genuinely usable free offering
  • Custom sensor scripting and advanced configuration still require real monitoring expertise; the polished UI does not remove the underlying complexity of correctly instrumenting a large network

Can I use NetBird for free?
Yes. NetBird has a free tier, so you can try it without paying. PRTG Network Monitor starts at On request.
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 PRTG Network Monitor is typically brought in for.
What can NetBird do that PRTG Network Monitor cannot?
NetBird covers WireGuard data plane, NAT traversal with relay fallback, Identity based access control, Network routes. PRTG Network Monitor covers Sensor-based monitoring, Auto-discovery, Multiple monitoring technologies, Maps and dashboards.

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.

PRTG Network Monitor: Is PRTG licensed per device or per sensor?

Per sensor. Each individually monitored metric counts as one sensor, so a single device is typically several sensors.

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.

PRTG Network Monitor: Can I combine two PRTG licence tiers on one server?

No, Paessler states different license sizes cannot be combined on one PRTG installation.

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.

PRTG Network Monitor: Is there a free tier?

Yes, PRTG offers a free tier limited to 100 sensors, which most production networks will exceed quickly.

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.
