Fiddler Everywhere vs Reqable

Fiddler Everywhere captures, inspects, modifies, and replays HTTP/S traffic across applications, services, and devices. Capture options include system proxy, network, browser, and terminal modes. It decodes HTTP/2, SignalR, WebSockets, MessagePack, SSE, gRPC, and Protobuf. Users can compose API requests, replay traffic, set breakpoints, and create rules that change requests or responses. Its MCP server connects to coding assistants and agent-powered IDEs, with setup documented for VS Code, Cursor, Claude Code, GitHub Copilot CLI, and Codex CLI. Output sanitization can remove sensitive information before data is shared with a model. The product is aimed at developers, QA staff, and support engineers. Desktop downloads are listed for Windows 10 and 11, macOS 11 or later on Intel or Apple Silicon, and Ubuntu 20 or later; Android and iOS are also listed as platforms. A 10-day trial is available, but there is no free plan. Lite costs $10 a month and Pro $19 a month, both billed monthly; Enterprise costs $37 a year, billed annually.

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.
