Generate a complete WireGuard client and server configuration locally — including key pair.

Note: these keys are generated locally in the browser (not real Curve25519 — see FAQ). For production use, generate real keys with "wg genkey" on the server.

Good to know about this tool

What does this tool do?

Creates a complete WireGuard client and server configuration template with an example key pair, serving as a starting point for a real VPN setup.

Why does it exist?

Because manually assembling a WireGuard configuration is error-prone, and a ready-made template saves time.

Typical use cases

Create a quick starting point for a new WireGuard VPN
Prepare a client configuration file for employees
Understand the structure of a WireGuard configuration

Best practices & notes

Always generate real keys with "wg genkey" on a trusted system, never use the example keys generated here in production
Never send private keys via email or chat
Keep AllowedIPs as narrow as possible when a full tunnel isn't needed

Frequently Asked Questions

Are the generated keys real WireGuard keys?

No. For security and compatibility reasons, no real Curve25519 is computed in the browser here — the values are placeholders for the configuration structure only. Generate real keys with "wg genkey".

Is my data transmitted?

No, all inputs and keys stay entirely in the browser.
