 * [Netmaker](https://github.com/gravitl/netmaker) [![netmaker github stars badge](https://img.shields.io/github/stars/gravitl/netmaker?style=flat)](https://github.com/gravitl/netmaker/stargazers) - Layer 3 peer-to-peer overlay network and private DNS. Similar to Tailscale, but with a self-hosted server/admin UI. Runs kernel WireGuard so very fast. Not FOSS, but the source code is available. Written in Go.
 * [NetBird](https://github.com/netbirdio/netbird) [![netbird github stars badge](https://img.shields.io/github/stars/netbirdio/netbird?style=flat)](https://github.com/netbirdio/netbird/stargazers) - NetBird is an open-source VPN management platform built on top of WireGuard® making it easy to create secure private networks for your organization or home.
 * [Firezone](https://www.firezone.dev/) [![firezone github stars badge](https://img.shields.io/github/stars/firezone/firezone?style=flat)](https://github.com/firezone/firezone) - Layer 3/4 overlay network. Runs on kernel WireGuard® and supports SSO using generic OIDC/SAML connectors. Distributed under Apache 2.0 license and written in Elixir/Rust.
+* [n2n](https://www.ntop.org/products/n2n/) - [![n2n github stars badge](https://img.shields.io/github/stars/ntop/n2n?style=flat)](https://github.com/ntop/n2n/stargazers) - Built on nodes and supernodes. GPL-3.0 license. Written in C.
 * [innernet](https://github.com/tonarino/innernet) [![innernet github stars badge](https://img.shields.io/github/stars/tonarino/innernet?style=flat)](https://github.com/tonarino/innernet/stargazers) - Similar to Netmaker, nebula, and Tailscale. Takes advantage of existing networking concepts like CIDRs and the security properties of WireGuard to turn your computer's basic IP networking into more powerful ACL primitives. Written in Rust.
 * [Pritunl](https://pritunl.com/) [![pritunl github stars badge](https://img.shields.io/github/stars/pritunl/pritunl?style=flat)](https://github.com/pritunl/pritunl/stargazers) - Seems quite comprehensive and complicated. OpenVPN, WireGuard, and IPSec support.
 * [Tinc](https://github.com/gsliepen/tinc) [![tinc github stars badge](https://img.shields.io/github/stars/gsliepen/tinc?style=flat)](https://github.com/gsliepen/tinc/stargazers) - Tinc is a peer-to-peer VPN daemon that supports VPNs with an arbitrary number of nodes. Instead of configuring tunnels, you give Tinc the location and public key of a few nodes in the VPN. After making the initial connections to those nodes, tinc will learn about all other nodes on the VPN, and will make connections automatically. When direct connections are not possible, data will be forwarded by intermediate nodes. Written in C.
