Most people searching "headscale vs tailscale" already know what Tailscale is. What trips people up is what Headscale actually replaces. It isn't a different mesh VPN client, it's a self-hosted, open source stand-in for Tailscale's coordination server. You still install the same official Tailscale app on your laptop and phone, it just talks to a server you run instead of Tailscale's cloud.
That one detail changes the whole calculation. You're not choosing a different client experience, you're choosing who holds the map of your network: Tailscale's infrastructure, or your own.
Quick answer

How Headscale actually works
Tailscale's product is really two things: the client app that builds an encrypted WireGuard mesh between your devices, and a coordination server that helps those devices find each other, hands out keys, and enforces access rules. Headscale, written in Go and BSD-3 licensed, reimplements only the second part. The actual peer-to-peer traffic between your devices never touches Headscale or Tailscale's servers either way, that part was always end-to-end. What changes is who runs the coordination layer that makes the mesh possible in the first place.
How to choose between Headscale and Tailscale
Three questions cover most of the decision:
- Does your network metadata need to stay off a third party's servers? With Tailscale, your device list, network topology, and access rules live on Tailscale's infrastructure, even though your actual traffic is encrypted and peer-to-peer. If that metadata alone is a dealbreaker, Headscale is the only option here.
- Do you want to maintain a server? Headscale means you patch it, back it up, and troubleshoot it when something breaks. Tailscale means none of that, it's a hosted service you sign up for.
- How many devices, and how many awkward networks? Tailscale's free tier (100 devices, 3 users) covers most homelabs and small teams outright, plus its roughly 200 global DERP relays quietly solve NAT traversal problems you'd otherwise have to debug yourself.
Headscale: your own Tailscale control plane
Headscale is BSD-3 licensed and has reached the point where it's stable for personal and small-organization use, with thousands of production deployments. It supports the core of what Tailscale offers: MagicDNS, Taildrop file sharing, subnet routing, exit nodes, dual-stack IPv4/IPv6, access control lists, and single sign-on through OIDC. There's no artificial cap on users or devices, the only limit is what your server can handle.
Key features
- Full compatibility with the official Tailscale client apps, no custom software to install
- MagicDNS, Taildrop, subnet routing, and exit node support
- Access control lists and pre-authenticated keys for automated device enrollment
- OIDC-based single sign-on for user authentication
- No per-user or per-device limits
Pros
- Zero per-user cost, ever, regardless of team size
- Network metadata and device list never leave your own server
- No artificial device or user caps to run into later
Cons
- No official web UI, you're on the CLI unless you add Headplane separately
- You own patching, backups, and uptime for the coordination server
- No built-in global relay network, NAT traversal in tricky networks takes more of your own configuration
Tailscale: managed, zero-maintenance mesh VPN
Tailscale is the commercial product Headscale reimplements the server side of. It's built on WireGuard, adds identity-based access control on top, and backs it with roughly 200 DERP relay servers worldwide that quietly handle the NAT and firewall situations that would otherwise need manual troubleshooting. The free tier covers 100 devices and 3 users, generous enough for most homelabs and small side projects. Paid plans start around $6 per user per month and scale up to a $18 per month Premium tier with deeper SSO integrations (Okta, SAML, Google, Microsoft, GitHub, GitLab).
Key features
- Zero server maintenance, it's a fully managed coordination service
- Roughly 200 DERP relay servers globally for reliable NAT traversal
- Free tier covers 100 devices and 3 users with no time limit
- Deep enterprise SSO integrations out of the box
- Official, polished web console for managing your tailnet
Pros
- Genuinely zero maintenance, sign up and it works
- The free tier alone covers most small teams and homelabs
- Global relay network solves NAT problems you'd otherwise debug yourself
Cons
- Per-user pricing once you outgrow the free tier
- Your network topology and device metadata sit on Tailscale's infrastructure
- Free tier caps (100 devices, 3 users) eventually force a paid plan for growing teams
Headplane: the web UI Headscale doesn't ship
Run Headscale for more than a weekend and the CLI-only workflow starts to wear thin, that's the gap Headplane fills. It's a community-built, feature-complete web interface for Headscale: machine management (expiry, routing, ownership), detailed ACL and tagging configuration, OIDC login, DNS settings, and the ability to edit Headscale's own configuration, all from a browser instead of SSH and a text editor. It isn't an official Headscale or Tailscale project, but it's actively maintained and is the closest thing to Tailscale's own polished admin console that the self-hosted side has.

Why we run Headscale for clients
Most teams that come to us about Tailscale aren't unhappy with the product, they're uncomfortable with their network map sitting on someone else's servers, or they've watched the per-user bill grow every time they onboard someone new. Headscale removes both problems without changing what end users see day to day, they still install the same Tailscale app they'd use anyway. We package it as a ready-to-launch AMI with the coordination server, ACLs, and TLS already configured, so the part that normally takes a weekend of reading docs is done before the instance finishes booting.
Our Headscale developer guide covers the full manual setup if you'd rather run it yourself first.
Where I'd start
Want zero maintenance and you're under 100 devices: just use Tailscale's free tier, there's no reason to add server upkeep you don't need yet. Uncomfortable with your network metadata on a third party's infrastructure, or scaling past the point where per-user pricing adds up: Headscale, paired with Headplane if you want a web UI instead of the CLI.
Either way you're not locked in. Since both speak the same protocol to the same client software, moving from Tailscale to a self hosted Headscale setup later is a config change, not a migration project.
Frequently Asked Questions
Headscale vs Tailscale: what's the actual difference?
Headscale is an open source, self-hosted replacement for Tailscale's coordination server. You still run the official Tailscale client on every device, it just talks to your own Headscale server instead of Tailscale's cloud. The mesh networking itself is identical.
How do I set up Tailscale self hosted with Headscale?
Run the Headscale server (Docker or a native binary), point your Tailscale clients at it with --login-server, then register each device with a pre-auth key. Add Headplane afterward if you want a web UI instead of the CLI for day-to-day management.
What is the Headscale setup process like compared to Tailscale?
Slightly more work upfront, you're standing up and maintaining a server, generating pre-auth keys, and configuring ACLs by hand or through Headplane. Tailscale's setup is a signup and an install command. Once running, day-to-day use is identical for both.
Is there a good tailscale alternative self hosted with a web UI?
Yes, Headscale plus Headplane. Headscale doesn't ship a web UI on its own, Headplane is the community project that adds one, covering node management, ACLs, DNS settings, and OIDC login.
What is Headplane UI and do I need it?
Headplane is a third-party web interface for Headscale that replaces the CLI for managing nodes, ACLs, and DNS. You don't need it, Headscale works fully from the command line, but most people running it beyond a handful of devices add Headplane for the visibility.
Is Headscale as reliable as Tailscale for a small team?
For personal and small-organization use, yes, Headscale has been running in production for thousands of deployments. The main gap is Tailscale's global DERP relay network for NAT traversal; Headscale can use DERP too, you just need to run or configure the relay yourself.
