Managing private networks can feel like a juggling act. You want privacy, control, and flexibility, but you also don’t want to be tied to a commercial service. That’s where Headscale comes in. It’s a self-hosted, open-source alternative to the Tailscale control server, offering network enthusiasts and organizations more autonomy and security.
If you’re tired of handing over sensitive data to third-party servers or simply love tinkering with your own infrastructure, Headscale might be your go-to solution. Let’s break it down so you can see why it’s worth exploring.
What Is Headscale?
Headscale is a self-hosted replacement for the Tailscale control server. For those new to Tailscale, it’s a tool that simplifies private networking by creating secure connections between devices without complex setups. But the catch? Tailscale’s control server is proprietary, meaning you rely on their infrastructure.
Headscale changes the game by offering an open-source alternative. This allows hobbyists, self-hosters, and organizations to take charge of their networks without giving up privacy or control.
Why Choose Headscale Over Tailscale?
Many people love Tailscale’s ease of use, but the idea of handing over control to an external server doesn’t sit well with everyone. That’s where Headscale steps in. Here are some key reasons to make the switch:
1. Total Control Over Your Network
- Self-hosted: You run Headscale on your own server, whether that’s a Raspberry Pi, a virtual private server, or your home lab.
- Data stays with you: No more sending sensitive information to third-party servers.
2. Open-Source Freedom
- Transparency: Open-source code means you can inspect, modify, or extend Headscale to suit your needs.
- Community-driven improvements: Contributions from developers worldwide make the project stronger.
3. Cost-Effective
- Running Headscale doesn’t require paying subscription fees. You can set it up using free or low-cost hosting solutions.
4. Customization
- Configure your setup to match exactly what you need—no compromises.
How Does Headscale Work?
Headscale functions as the control plane for your Tailscale-compatible network. Think of it as the brain that coordinates secure connections between devices. Here’s how it typically works:
- Install Headscale on a server you own.
- Connect your devices using the Tailscale clients, just like you would with Tailscale’s server.
- Enjoy private, peer-to-peer networking without sacrificing control or privacy.

Headscale vs Tailscale
Let’s break down the differences between these two tools:
| Feature | Tailscale | Headscale |
|---|---|---|
| Hosting | Proprietary control server | Self-hosted |
| Cost | Subscription-based | Free (with your own hardware) |
| Source Code | Closed | Open-source |
| Privacy | Relies on external server | Data stays local |
| Customizability | Limited | High |
If you value transparency, privacy, and flexibility, Headscale wins hands down.
Real-Life Example:
A friend of mine runs a small IT consultancy. He loved Tailscale’s simplicity but didn’t want to send client data through a third-party server. After switching to Headscale, he got the best of both worlds—an easy-to-use private network and complete control over sensitive information.
It took him a weekend to set it up, and now he saves on subscription fees while offering clients more secure solutions.
