Short summary
Lens is an open-source Rust project that visualizes application traffic during local development using a transparent proxy architecture, eliminating the need to manually piece together logs and packet captures. It currently supports HTTP/1.1 and PostgreSQL protocol decoding with automatic secret redaction, a modular Cargo workspace, and a plugin-oriented design. The author is seeking feedback on the architecture and contributions from developers experienced in async networking and protocol parsing.
