gori (고리) is a free/open-source TUI web proxy (MITM) written in Crystal.
gori (고리 — Korean for ring, link, loop) sits in the loop between your client
and its target, capturing every request and response as a flow you can
intercept, replay, fuzz, and scan across HTTP/1.1, HTTP/2, WebSocket, gRPC and
SSE. Every action is also a gori run subcommand and an MCP tool, so scripts
and AI agents can drive the same engagement.
