Fluxzy vs Reqable

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.

Reqable is a cross-platform HTTP development and debugging tool for API debugging, testing, and traffic analysis. It is available on Android, iOS, Linux, macOS, and Windows. Its debugging proxy supports HTTP/1.x and HTTP/2, WebSocket, HTTP, HTTPS, SOCKS4, SOCKS4a, and SOCKS5 proxies, plus TLS versions 1.1 through 1.3. API testing also supports HTTP/3 (QUIC) and Server-Sent Events. Developers can rewrite requests, set breakpoints, modify responses, and process request or response data with Python scripts. Collections can be imported from Postman, Swagger, Insomnia, Hoppscotch, ApiFox, ApiPost, RapidAPI (Paw), cURL, and HAR. Collections remain local when signed out; signing in enables cloud storage and device syncing. The mobile app can forward traffic to the desktop app through a VPN service, but omits rewrite, breakpoint, and script features. API debugging requires a CA certificate. The Community edition permits commercial use and costs nothing, with one device and 100MB of storage. Premium costs $49.90 a year for up to six devices and 1GB of storage.
