Nebula is a scalable overlay networking tool (mesh VPN) built on the Noise Protocol Framework, using certificates and security groups for mutually authenticated peer-to-peer tunnels. It connects machines across clouds, datacenters, and endpoints, scaling from a few nodes to tens of thousands.
Use cases
- connect servers across clouds into a private network
- set up a mesh vpn between my machines
- replace openvpn with something faster
- peer-to-peer networking with udp hole punching through NAT
- secure communication between thousands of nodes
- build a software-defined network with certificate-based access control
When to choose
- you need a scalable, performant mesh VPN across many platforms
- you want certificate-based identity and group-based traffic filtering
- you need NAT traversal and hole punching without a central chokepoint
When to avoid
- you need a simple point-to-point consumer VPN with a GUI out of the box
- you require IPsec/OpenVPN compatibility or traditional client-server VPN topologies
- you need TCP-only transport (Nebula is UDP-based)
