About g3proxy

g3proxy is a forward proxy server in the open-source g3 project, supporting proxy chaining, protocol inspection, TLS MITM interception, ICAP adaptation, and transparent proxy deployments. Written in Rust and released under the Apache-2.0 license, it is configured through a detailed configuration reference with defined metrics and log formats for production observability. It is aimed at network engineers and platform teams who need a performant, inspectable forward proxy they can self-host and adapt to complex egress, security, and compliance requirements.
