Fiddler Everywhere
Fiddler Everywhere captures and works with HTTP/S traffic moving across applications, services, and devices.
What Fiddler Everywhere is
Fiddler Everywhere captures and works with HTTP/S traffic moving across applications, services, and devices. Capture options include a system proxy, network, browser, or terminal. It decodes HTTP/2, SignalR, WebSockets, MessagePack, SSE, gRPC, and Protobuf traffic. Users can compose API requests, replay captured traffic, set breakpoints, and create rules that change requests or responses. An MCP server connects with coding assistants and agent-powered IDEs, with setup documented for VS Code, Cursor, Claude Code, GitHub Copilot CLI, and Codex CLI; its output sanitization can remove sensitive information before it 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. A 10-day trial is available. The listed plans include Lite at $10 per user per month billed monthly, Pro at $19 per user per month billed monthly, and Enterprise at $37 per user per month billed annually.
