GoKawiilNew open-source tool wg-admin adds a web UI to existing WireGuard servers
A developer released wg-admin, a self-hosted web interface designed to manage WireGuard VPN servers that are already configured and running. Rather than generating new configs or replacing wg-quick, it reads existing files in /etc/wireguard, lets admins add, rename, rotate or remove peers, and applies changes using wg syncconf so the tunnel doesn't restart. It also generates client config files and QR codes, shows live handshake and traffic data, and backs up configs before writing changes.
