Nebula Overlay Networks: Simple, Fast, and Secure
Extend network access with on-demand, encrypted tunnels between any hosts on any network

Nebula open source software powers production networks accessed by millions of users
Innovative companies with high expectations of availablility and reliability run their networks with Nebula. Slack open sourced the project after years of R&D and deploying it at scale.
Nebula is a lightweight service that's easy to distribute and configure on modern operating systems. It runs on a wide variety of hardware including x86, arm, mips, and ppc.
Traditional VPNs come with availability and performance bottlenecks. Nebula is decentralized: Encrypted tunnels are created per-host and on-demand as needed.
Created by security engineers, Nebula leverages trusted crypto libraries (Noise), includes a built-in firewall with granular security groups, and uses the best parts of PKI to authenticate hosts.
From initial handshake to heavy usage, Nebula was designed to be as efficient as possible without compromising security or reliability.
Overlay networks are only as conveient as they are trustworthy. Nebula was designed to be secure from the ground up.
Nebula is freely available as an open-source project. Check out our Getting Started guide and try it out for yourself.
