In their own words
Fluxzy
Fluxzy is an HTTP proxy for recording, analyzing, debugging, and changing HTTP/1.1, HTTP/2, and WebSocket traffic, over plain or secure channels. Its proxyless capture records application traffic without proxy configuration, including apps that ignore system proxy settings. Rules can change headers, add authentication, simulate slow networks, forward requests, spoof DNS, alter TLS fingerprints, and force HTTP versions. It can decode gRPC and Protobuf traffic, and inspect OpenAI, Anthropic, and Google Gemini API requests and responses, including streams and tool calls. Captures can be exported as HAR, Fiddler SAZ, PCAPNG, cURL commands,.http files, or native.fxzy files. Fluxzy works offline without an account or cloud sync, and its site says it has no telemetry. Community is free for personal use and adds an x-fluxzy-community header. Pro is €49, paid once; Enterprise is €59, paid once with a three-seat minimum.
