It utilizes holepunching and relay protocols for NAT traversal to establish encrypted tunnels through firewalls without requiring inbound ports. The platform includes a control plane for managing

EasyTier is a decentralized peer-to-peer virtual private network and mesh networking tool. It functions as a layer 3 network overlay that establishes secure tunnels between devices without requiring a centralized server or coordinator. It also serves as a WireGuard-compatible VPN, capable of acting as a server for standard WireGuard clients. The project distinguishes itself through multipath latency-based routing and the use of KCP or QUIC proxies to mitigate packet loss and stabilize connections in high-loss environments. It provides a virtual networking manager featuring a web management co

Nebula is a scalable, decentralized overlay networking tool designed to create secure, encrypted peer-to-peer connections between distributed hosts. By utilizing a certificate-based identity authority, it enables the construction of private communication fabrics across disparate physical infrastructures, such as multiple cloud providers or on-premises data centers, without requiring central authentication servers. The project distinguishes itself through a zero-trust architecture that enforces granular, policy-driven firewall filtering based on certificate-derived group memberships. It facili

n2n is a peer-to-peer VPN that creates an encrypted mesh network by establishing layer 2 overlay networks. It uses UDP tunneling to connect remote computers into a shared virtual local area network, allowing devices to communicate as if they were on the same physical Ethernet switch. The system utilizes a centralized signaling registry and federated coordination nodes to facilitate peer discovery and node registration. It implements NAT traversal through UDP hole punching and UPnP port mapping, while using supernode relay routing to ensure connectivity when symmetric NATs prevent direct peer-

Ziti is a zero-trust network overlay and identity-based mesh network. It provides a software-defined perimeter that replaces traditional IP-based routing and VPNs by mapping network services to cryptographically verified identities, effectively cloaking applications from the public internet. The project distinguishes itself through an outbound-only connection model that eliminates open listening ports and a Zero Trust SDK that allows developers to embed encryption and identity-based access control directly into application source code. It also provides transparent tunneling proxies to extend

ZeroTierOne is a software-defined networking engine that creates virtual local area networks by emulating Ethernet switches across distributed devices. It functions as a peer-to-peer platform, establishing encrypted tunnels directly between endpoints to bypass the need for centralized gateways or hub-and-spoke architectures.
