Huginn Proxy

High-performance reverse proxy: passive TLS, HTTP/2, and TCP SYN (eBPF) fingerprints, injected as trusted headers for your backends.

100% open source. Fingerprints come from Huginn Net; proxy and signature path are both MIT/Apache. No proprietary fingerprint stack, no extra license for commercial use.
