Headscale
Headscale is an open source, self-hosted implementation of the Tailscale control server for managing a private tailnet, nodes, keys, IPs, and routes.

Headscale is an open source, self-hosted implementation of the Tailscale control server. It coordinates a WireGuard-based overlay network by exchanging node keys, assigning addresses, and managing routes and sharing within a tailnet.
Key Features
- Implements core control-plane functions for a Tailscale-compatible network (tailnet)
- Node registration and coordination via Tailscale clients
- WireGuard key exchange and IP address management
- User/namespace boundaries and machine sharing between users
- Route advertisement and management for subnet routing
- Designed for a single tailnet suited to personal use or small organizations
Use Cases
- Run a private Tailscale-compatible VPN without relying on the hosted control server
- Connect homelab, servers, and remote devices via a WireGuard-based overlay network
- Provide secure remote access and subnet routing for a small team or community project
Limitations and Considerations
- Focused on a narrow scope: a single tailnet rather than large multi-tenant deployments
- Some Tailscale features may be unavailable or behave differently depending on client support and Headscale version
Headscale is a practical choice for self-hosters who want the Tailscale experience with an open control plane. It emphasizes a lean, hobbyist-friendly approach while supporting common coordination features needed for a private overlay network.
