DSVPN is a dead-simple, single-binary VPN tool written in C that tunnels traffic over TCP with modern, formally verified cryptography. It requires no configuration files or firewall rules—just a shared key and one command on the server and client.

Use cases

• set up a simple personal vpn server
• secure traffic on untrusted public wifi
• bypass restrictive networks that only allow tcp 443
• create a point-to-point encrypted tunnel between two machines
• replace openvpn/wireguard with a minimal zero-config vpn
• prevent ipv6 leaks when connected to a vpn

When to choose

• you want a minimal, zero-configuration vpn with a tiny code base
• you need to tunnel through networks where only TCP/443 is open
• you prefer no external dependencies and constant memory usage
• you run Linux, macOS, or a BSD and are comfortable with the command line

When to avoid

• you need UDP-based performance like WireGuard for high-throughput use
• you need multi-client user management, GUI clients, or mobile apps
• you need advanced features like split tunneling or centralized key management
• you need Windows support
