Proven technology, deployed at scale
Nebula open source software powers production networks accessed by millions of users
Trusted and stable
Innovative companies with high expectations of availability 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.
Mesh VPN architecture
Traditional VPNs come with availability and performance bottlenecks. Nebula is decentralized: Encrypted tunnels are created per-host and on-demand as needed.
Secure by design
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.
Nebula is freely available as an open-source project. Check out our Getting Started guide and try it out for yourself.
