Warpgate

Warpgate is a 100% open-source Python 3 library for one-shot NAT traversal, enabling direct peer-to-peer connections between devices behind NATs without requiring relay servers or key management. It targets developers, IT, and operations teams in organizations of any size, particularly those building network applications or needing to connect peers across restrictive networks. It differentiates itself by offering a plugin cascade with eight traversal techniques, built-in signaling and discovery infrastructure, and a permissive MIT license with community-run public infrastructure.
