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.

ProxyHawk is a native macOS proxy debugger for capturing and inspecting HTTP traffic from Mac apps, iPhones, iOS Simulator, Android devices, and Android emulators. Mobile traffic routes through the Mac, where capture and display happen locally without uploading HTTP content to a vendor cloud. Its API Client composes and replays requests, imports cURL, and exports Postman collections with environment variables. API Guard checks responses for removed fields, changed types, and missing array items, and can alert through Slack and email. Other tools include breakpoints, block rules, local and remote mapping, scripts, network throttling, request and response editing, and response mocking. Shared sessions strip Authorization headers, cookies, and tokens client-side; links expire after seven days. ProxyHawk requires macOS 13 or later and has no Windows or Linux version. The Free plan captures up to 500 requests per day but excludes SSL/TLS decryption, breakpoints, block rules, scripting, and mapping. Paid plans start at ₹417/mo, and a free trial is offered.
