Both projects answer the same question — how do I run a WireGuard mesh without a company holding the map? — and both answer it honestly. The difference is not features, and it is not performance. It is which dependency you are willing to carry.
The one-sentence version
Headscale replaces Tailscale's coordination server with one you run, and keeps the official Tailscale clients. NetBird replaces the entire product: its own agent, its own management server, its own dashboard, its own identity layer — WireGuard underneath, nothing borrowed above it.
That single structural difference drives almost everything else.
Where the dependency sits
This is the part to settle first, because no feature comparison survives it.
With Headscale, your server is yours, but the client is software maintained by Tailscale Inc., pointed at your server through an overridable login URL. That arrangement has held for years, and it is not contractual. If you want the trade-off in the other direction, Tailscale's managed service versus Headscale is the comparison that frames it as SaaS versus self-hosting.
With NetBird, the client is the project's own agent. Nobody upstream can change the protocol under you — and in exchange, the platform coverage, the release cadence and the long-term survival of the project are all NetBird's to deliver. Running NetBird self-hosted walks through what that actually involves.
Neither is safer in the abstract. One asks you to trust a client vendor's continued tolerance; the other asks you to bet on a smaller project owning its whole stack.
Moving parts, counted honestly
Headscale is a Go binary and a database. That is the deployment. Adding a machine is a login command on a client most people already have.
NetBird's default install brings up several services together: a management server, a signal server, a TURN relay for connections that refuse to go direct, a dashboard, and an identity provider. The published docker-compose makes that one command — but one command is not one service. It is more surface to patch, monitor and back up.
The honest framing: NetBird gives you more out of the box, Headscale gives you less to maintain. Which of those is the bargain depends on whether you wanted an admin UI in the first place.
Identity, and why it separates them
NetBird treats identity as part of the product. SSO, group mapping and device approval are the expected path, not an extension. If your answer to "who is allowed on this network" needs to come from Google Workspace, Okta, Entra or Authentik, that is a documented setup rather than a project.
Headscale supports OIDC, so it can point at your provider — but the surrounding management surface is deliberately thinner. Headscale's job is to speak the Tailscale protocol correctly, not to be a device-management product. Access control lives in Tailscale-compatible ACL files, which is excellent if you want a reviewable file in version control, and sparse if you wanted an interface.
A table that does not dodge
| If this describes you | Lean towards |
|---|---|
| Laptops and phones belonging to people who should never see a config file | Headscale |
| You want SSO, groups and device approval inside one product | NetBird |
| You want the fewest services to run, patch and back up | Headscale |
| You refuse to depend on another company's client at all | NetBird |
| You want access rules as a reviewable file in Git | Headscale |
| You want an admin UI on day one | NetBird |
What we would not claim
We would not tell you one is faster. Both carry traffic over WireGuard, both punch through NAT and both fall back to a relay when they cannot — a TURN server for NetBird, DERP for Headscale. On any given link the deciding factor is your path and your hardware, not the badge on the control plane. If throughput is genuinely your constraint, measure your own route before you let a comparison table choose for you.
We would also not tell you that self-hosting the control plane makes the mesh highly available. In both projects, an unreachable control plane leaves existing tunnels running while new enrolments, key rotation and policy changes stop. That is a good failure mode, and it means what you need is a backup of the control plane's state — not a cluster.
The honest verdict
Pick Headscale if you want the smallest thing that works and you are comfortable that the client comes from someone else. Pick NetBird if you want identity, policy and an interface to be part of the same product, and you would rather own the whole stack than borrow the best-maintained part of it.
If neither dependency appeals and you would rather run a mesh with its own certificate authority, that is a third shape entirely — Headscale compared with Nebula takes that fork.
