Alternatives to WireGuard
The modern VPN protocol and reference tools
WireGuard ranks #11 of 11 in Mesh VPNs, with an Alt Score of 40. It is licensed under GPL-2.0, free from Free and available on Windows, macOS, Linux, iOS and Android. 4 of 12 checklist rows are verified against a public source.
Linux kernel developers, network administrators, and everyday users who want a VPN that's easy to configure and audit — from individuals securing personal devices to admins running backbone infrastructure.
A VPN with a minimal, auditable codebase and configuration comparable to setting up SSH. It runs as a network interface with a private key and a list of authorized peers, each peer's IP addresses acting as a cryptographic routing table (cryptokey routing). It's integrated directly into the Linux kernel for speed and low overhead, with clients also available for Windows, macOS, BSD, iOS, and Android, plus support for containers and network namespaces.
WireGuard tunnels IP packets inside UDP, authenticating and encrypting them using the Noise protocol framework with Curve25519 for key exchange, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2 for hashing. Peers are identified only by public keys, and each peer is bound to a set of allowed IP addresses that double as both routing rules and access control.

Firezone is an open-source, self-hostable remote access platform built on WireGuard that creates direct, encrypted peer connections between users and internal resources through lightweight gateways.
Headscale is an open-source coordination/control server that is API-compatible with the official Tailscale client apps, letting teams self-host their own control plane while keeping the same mobile an.
OpenZiti is an open-source, programmable zero-trust networking platform stewarded by NetFoundry that builds an overlay fabric of routers and identities instead of exposing listening ports on hosts.
Defguard is an open-source, Rust-built WireGuard VPN manager that adds multi-factor authentication, an identity/SSO gateway, and a web UI for managing peers, gateways, and access policies.
Nebula is an open-source peer-to-peer mesh networking tool originally built and battle-tested internally at Slack before being open-sourced.
