# headscale # Headscale
An open source implementation of the Tailscale coordination server. An open source implementation of the Tailscale coordination server.
## Disclaimer ## Status
- [x] Basic functionality (nodes can communicate with each other)
- [x] Node registration through the web flow
- [x] Network changes are relied to the nodes
- [ ] Node registration via pre-auth keys
- [ ] Multiuser support
- [ ] ACLs
- [ ] DNS
... and probably lots of stuff missing
## Roadmap 🤷
Adding multiuser support seems doable. Rather than actual users, this multi-tenancy will probably look more like namespaces in Kubernetes - a logical partitioning of resources created with a CLI.
Pre-auth keys should also be feasible.
Suggestions/PRs welcomed!
1. I have nothing to do with Tailscale, or Tailscale Inc. Just a fan of their tech.
2. The purpose of writing this was to learn a bit how Tailscale works. Hence the emojis in the log messages and other terrible code.
3. I don't use Headscale myself (their Solo plan + DERP infra is way more convenient).
4. Headscale adds all the machines under the same user. Be careful!
