A peer-to-peer VPN that connects laptops, servers, and microcontrollers over the internet with zero configuration.
Husarnet is a peer-to-peer VPN that creates a secure, low-latency virtual network to connect devices like laptops, servers, and microcontrollers over the internet without manual configuration. It enables direct, encrypted communication between devices, reducing dependency on central servers and simplifying cross-platform networking.
Developers and engineers building IoT projects, robotics systems (e.g., ROS1/2), or distributed applications that require secure, direct device-to-device connectivity across diverse platforms, including microcontrollers like ESP32.
Developers choose Husarnet for its zero-configuration setup, peer-to-peer architecture that minimizes latency, and lightweight design that runs on everything from servers to microcontrollers, offering end-to-end encryption without relying on a central IoT server.

Enables low-latency communication by connecting devices peer-to-peer, with infrastructure used only as a failover proxy, reducing dependency on central servers.
Adding devices requires just a single command like `husarnet join`, simplifying setup across Linux, Windows, macOS, and microcontrollers.
Reestablishes connections in 1-3 seconds during network topology changes, such as switching Wi-Fi hotspots, ensuring minimal downtime.
Runs on popular OSes and even microcontrollers like ESP32, enabling IoT projects without a central server, as highlighted in the README.
Uses X25519 for key exchange and ChaCha20-Poly1305 for encryption with perfect forward secrecy, ensuring all packets are encrypted.
Relies solely on IPv6 with `fc94::/16` routing, which may not integrate well in IPv4-dominated environments or with legacy systems.
Configuration often requires the Husarnet Dashboard, a web app hosted by the developers, introducing external reliance and potential privacy concerns.
The CLI was added in version 2.0.0 and is described as 'new', so it might lack the stability or feature completeness of established tools.
