Fiddler Everywhere
What Fiddler Everywhere is
Fiddler Everywhere is software for capturing and working with HTTP/S traffic across applications, services, and devices. Its capture modes include system proxy, network, browser, and terminal. It decodes protocols and formats such as 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 with coding assistants and agent-powered IDEs, including documented setups for VS Code, Cursor, Claude Code, GitHub Copilot CLI, and Codex CLI; output sanitization can protect sensitive information before sharing data with a model. Downloads are listed for Windows 10 and 11, macOS 11 or later on Intel or Apple Silicon, and Ubuntu 20 or later. A 10-day trial is available. Lite costs $10 per user per month billed monthly, Pro costs $19 per user per month billed monthly, and Enterprise costs $37 per user per month billed annually. Enterprise adds offline mode, managed installation and configuration, SSO, and priority support.
