About Husarnet
Husarnet connects devices over the internet so traffic flows directly between them rather than through a central server. The client creates a virtual network interface called hnet0, so existing software works without code changes. Networks are managed through the Husarnet Dashboard, and a self-hosted version of the base servers and dashboard is available.
It is aimed at robotics and embedded work: from the point of view of ROS and ROS 2 the network looks like a LAN, and Husarnet provides tools to configure and monitor ROS networks.
Strengths
- Direct peer-to-peer traffic without a relay in the middle
- Works as a normal network interface, no code changes needed
- ROS and ROS 2 aware tooling
- Self-hosted control plane available
Limitations
- Hosted setup relies on the Husarnet Dashboard account
- Focused on robotics and device fleets rather than general consumer VPN use

Alternatives to Husarnet
Compare allSoftware that can replace Husarnet for an important use case, and what changes if you switch.
Tailscale
Builds a private network between your own devices using WireGuard, without opening ports or running a server.
Tailscale builds a WireGuard mesh through NAT across desktop and mobile with a free Personal plan, but its coordination server is hosted and it has no ROS-specific tooling.
ZeroTier One
Puts machines anywhere in the world on the same virtual Ethernet network, as if they were plugged into one switch.
ZeroTier One joins devices into one Ethernet-level network with NAT traversal on many platforms, but relayed connections are slow and it lacks ROS tooling.
NetBird
A WireGuard-based mesh network with single sign-on, multi-factor authentication and access policies, self-hostable or managed.
NetBird offers open-source peer-to-peer WireGuard with SSO and access policies, self-hosted or managed, aimed at general machines and people rather than robot fleets.
nebula
Connect devices through an encrypted overlay network.
nebula is an MIT-licensed encrypted overlay network for desktop, server and mobile, but requires you to manage certificates and network configuration.
EasyTier
A decentralized mesh VPN written in Rust that links devices into one private network, with WireGuard support.
EasyTier links devices in a decentralized Rust mesh with no central server and WireGuard support, but needs more setup and much documentation is in Chinese.
tinc
A VPN daemon that builds an encrypted mesh network between hosts over the internet.
tinc builds an open-source full mesh with direct peer traffic between Linux hosts, but is configured by hand with config files.
Similar software
Related functionality, not necessarily a direct replacement.
WireGuard
A small, fast VPN protocol and set of official clients that connect two machines by exchanging public keys.
Netmaker
Self-hosted platform for building and managing WireGuard mesh networks.
n2n
A lightweight peer-to-peer layer-2 VPN for linking machines into a virtual network.
headscale
A self-hosted, open-source implementation of the Tailscale control server, so your mesh VPN does not depend on a company.
