An open source, self-hosted implementation of the Tailscale control server.

Note: Always select the same GitHub tag as the released version you use to ensure you have the correct example configuration and documentation. The main branch might contain unreleased changes.

What is Tailscale

Tailscale is a modern VPN built on top of Wireguard. It works like an overlay network between the computers of your networks - using NAT traversal.

Everything in Tailscale is Open Source, except the GUI clients for proprietary OS (Windows and macOS/iOS), and the control server.

The control server works as an exchange point of Wireguard public keys for the nodes in the Tailscale network. It assigns the IP addresses of the clients, creates the boundaries between each user, enables sharing machines between users, and exposes the advertised routes of your nodes.

A Tailscale network (tailnet) is private network which Tailscale assigns to a user in terms of private users or an organisation.

Design goal

Headscale aims to implement a self-hosted, open source alternative to the Tailscale control server. Headscale's goal is to provide self-hosters and hobbyists with an open-source server they can use for their projects and labs. It implements a narrow scope, a single Tailnet, suitable for a personal use, or a small open-source organisation.

Supporting Headscale

If you like headscale and find it useful, there is a sponsorship and donation buttons available in the repo.

  • Access control lists
  • MagicDNS
  • Support for multiple IP ranges in the tailnet
  • Dual stack (IPv4 and IPv6)
  • Routing advertising (including exit nodes)

Please have a look at the documentation.

Talks

Disclaimer

This project is not associated with Tailscale Inc.

However, one of the active maintainers for Headscale is employed by Tailscale and he is allowed to spend work hours contributing to the project. Contributions from this maintainer are reviewed by other maintainers.

The maintainers work together on setting the direction for the project. The underlying principle is to serve the community of self-hosters, enthusiasts and hobbyists - while having a sustainable project.

Contributing

Please read the CONTRIBUTING.md file.

Requirements

To contribute to headscale you would need the lastest version of Go and Buf(Protobuf generator).

We recommend using Nix to setup a development environment. This can be done with nix develop, which will install the tools and give you a shell. This guarantees that you will have the same dev env as headscale maintainers.

Code style

To ensure we have some consistency with a growing number of contributions, this project has adopted linting and style/formatting rules:

The Go code is linted with golangci-lint and formatted with golines (width 88) and gofumpt. Please configure your editor to run the tools while developing and make sure to run make lint and make fmt before committing any code.

The Proto code is linted with buf and formatted with clang-format.

The rest (Markdown, YAML, etc) is formatted with prettier.

Check out the .golangci.yaml and Makefile to see the specific configuration.

Install development tools

  • Go
  • Buf
  • Protobuf tools

Install and activate:

nix develop

Testing and building

Some parts of the project require the generation of Go code from Protobuf (if changes are made in proto/) and it must be (re-)generated with:

make generate

Note: Please check in changes from gen/ in a separate commit to make it easier to review.

To run the tests:

make test

To build the program:

nix build

or

make build
