I wanted a simple way to expose local dev servers to the internet that I could host myself, so I built Arbok. It's an open-source tunneling service that uses WireGuard for the data plane.

The server is a single Go binary that uses a userspace WireGuard implementation (`wireguard-go`), so it can run without root privileges and has no kernel dependencies, making it easy to deploy in a container.

What makes it different:

  1. Self-Hosted & Open Source:** Run it on your own domain and infrastructure. Full control, no surprises.
  2. Simple Client Experience:** A single `curl` command gets you a ready-to-use WireGuard configuration. No signup needed.
  3. Userspace WireGuard Server:** The server runs as an unprivileged user, which simplifies deployment and enhances security.

```

  # 1. Request a tunnel for your local service on port 3000
  $ curl https://arbok.mrkaran.dev/3000 > arbok.conf

  # The server responds with a config and your unique public URL.
  # The URL will be printed to your console, for example:
  #
  # Your app is live at: https://brave-snake-1234.arbok.mrkaran.dev

  # 2. Activate the tunnel using standard tools (requires sudo on client)
  $ sudo wg-quick up ./arbok.conf

I'm still actively developing it and would love to get your feedback, feature ideas, or contributions. Let me know what you think!
