The short version

  • Each has a real cost: Headscale the clients are proprietary software maintained by a company with no obligation to Headscale, so a client update can change protocol behaviour and break your control server until volunteers catch up.; ZeroTier the free tier caps at 10 devices and 1 network, which a small business will outgrow quickly and then face both a base plan fee and per-device overage charges
  • They diverge on capability: Headscale covers Self hosted control server, ZeroTier covers Peer-to-peer mesh networking.
  • 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.

Headscale

  • The clients are proprietary software maintained by a company with no obligation to Headscale, so a client update can change protocol behaviour and break your control server until volunteers catch up.
  • Features that live on the vendor side, including the admin console, Funnel and app connectors, do not exist here and cannot be added, so feature comparisons against Tailscale are misleading.
  • There is no official web interface, so day to day administration is a command line tool or one of several unofficial front ends of varying quality and maintenance.
  • It is deliberately single tenant, so a managed service provider cannot use one deployment to serve several customer networks.
  • Upgrades have required database migrations and policy format changes between releases, and with no support contract a failed migration on the control server is your problem alone.

ZeroTier

  • The free tier caps at 10 devices and 1 network, which a small business will outgrow quickly and then face both a base plan fee and per-device overage charges
  • Per-additional-device pricing on Essential ($2.00 each) is proportionally expensive for a team that grows just past the included count, since the jump from free to paid is immediate once the 11th device joins
  • Relay fallback, when a direct peer-to-peer path cannot be established (common behind certain NAT or firewall configurations), routes traffic through ZeroTier's infrastructure, adding latency and a dependency the buyer does not fully control
  • Enterprise and Quantum tiers are entirely custom-quoted, so very large deployments cannot be budgeted from the public pricing page
  • Network administration for larger deployments (Scale and above) still requires understanding ZeroTier's access control and network rule model, which has a real learning curve beyond simple device joining
  • As with any software-defined mesh network, security depends on correctly configured network authorization; a misconfigured network can expose devices more broadly than intended

Answered from the vendors’ own pages

Headscale: Is Headscale made by Tailscale?

No. It is an independent community project. Tailscale acknowledges it but does not support it, and the clients it relies on are the vendor ones.

ZeroTier: Is ZeroTier free for personal use?

Yes, the Personal plan is free for up to 10 devices and 1 network.

Headscale: What do I lose compared with the hosted service?

The admin console, the vendor relay network unless you use the public DERP servers, and hosted only features such as Funnel and app connectors.

ZeroTier: How does overage pricing work?

Beyond a plan's included device count, additional devices are billed individually per month, at $2.00 each on Essential and $1.80 each on Scale.

Headscale: Can I still use the public relay servers?

Yes, the default configuration can use them, though many self hosters run their own DERP to remove that dependency.

ZeroTier: Is there a nonprofit or education discount?

Yes, registered charities and educational organisations receive up to 50% off.

Headscale: Is it suitable for a company network?

For a technical team, yes. There is no vendor to escalate to, so it needs someone on staff who is willing to own the control server.
