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.; Zscaler Internet Access the pricing page names two base tiers, Essentials Platform and Zscaler Platform, plus modular add ons including three Digital Experience Monitoring tiers, but publishes no dollar figures anywhere and routes buyers to a demo request for cost
  • They diverge on capability: NetBird covers WireGuard data plane, Zscaler Internet Access covers Secure web gateway.
  • 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.

Zscaler Internet Access

  • The pricing page names two base tiers, Essentials Platform and Zscaler Platform, plus modular add ons including three Digital Experience Monitoring tiers, but publishes no dollar figures anywhere and routes buyers to a demo request for cost

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.

Zscaler Internet Access: How many pricing tiers does Zscaler Internet Access offer?

Zscaler Internet Access offers two main platform bundles: the Essentials Platform (entry-level) and the Zscaler Platform (comprehensive). Specific pricing is not published online.

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.

Zscaler Internet Access: Are there optional add-on modules available?

Yes. Zscaler offers extensive optional capabilities in five categories including Inline Cyberthreat Protection, Private Access enhancements, Data Security, Security Operations, and Zero Trust Branch.

Source
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.

Zscaler Internet Access: How is Zscaler Zero Trust Branch priced?

Zero Trust Branch is sized by encrypted throughput (200 Mbps to 10 Gbps) or endpoint count (200 to 5,000 endpoints), with pricing varying by configuration.

Source
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.

Zscaler Internet Access: How do I get Zscaler pricing?

Zscaler does not publish pricing online. You must request a demo or contact their sales team to receive a pricing quote.
