WireGuard explained: why self-hosting your own VPN beats a subscription

WireGuard is a modern VPN protocol designed to be small, fast and easy to audit. Where older protocols carry decades of accumulated complexity, WireGuard's codebase is deliberately tiny — which is exactly why security researchers like it.

**What a VPN actually does.** It creates an encrypted tunnel from your device to a server, so your traffic leaves that server rather than your home connection. That changes your apparent location and protects your traffic on untrusted networks such as hotel or café Wi-Fi.

**Why self-hosting changes the equation.** With a commercial VPN you are trusting a company not to log or misuse your traffic — you cannot verify their claims. When you run your own endpoint, there is no third party in the path. You generate the keys, you own the server, and only you can see anything.

**The practical advantages of your own endpoint:**

- **A dedicated IP.** You get an address that is yours, not one shared with thousands of strangers whose bad behaviour gets it blocked. - **No bandwidth throttling.** Your limit is your VPS, not a vendor's fair-use policy. - **Split tunnelling.** Route only the subnets you choose through the tunnel and keep the rest on your normal connection. - **Mesh networking.** Connect several endpoints — office, home, cloud — into one private network.

**What it is not.** A self-hosted VPN does not make you anonymous; it moves where your traffic exits. And you are responsible for keeping the server patched. Those are real responsibilities, but they are also why the result is more trustworthy than any subscription you cannot inspect.
