Anything Analyzer

Anything Analyzer is a desktop protocol analyzer that brings browser traffic and HTTPS proxy captures into the same session for AI analysis. It runs on Windows, macOS (Intel and Apple Silicon) and Linux. It's for developers and security researchers investigating APIs, authentication flows, request signatures and JavaScript encryption.

The embedded browser captures web requests, while the built-in MITM proxy captures traffic from desktop apps, command-line tools, scripts, mobile apps and IoT devices. You can inspect request and response headers and bodies, filter traffic by domain, and export raw requests as JSON. Browser storage snapshots record changes to cookies and local storage alongside the traffic.

AI analysis filters noisy requests before examining relevant traffic in depth. It can produce API documentation, explain authentication, generate Python reproduction code, and examine security or performance issues. JavaScript hooks capture encryption calls, and code extraction pulls encryption-related snippets into the analysis. Reports support follow-up questions, custom prompts and analysis of selected requests.

The app uses local SQLite storage and doesn't bundle an AI model. Analysis connects to OpenAI, Anthropic or a custom compatible API; cloud providers receive the traffic supplied for analysis. Its MCP server lets Claude Desktop and Cursor call capture and analysis tools, while an MCP client connects external tools. The project is open source under Apache 2.0. The proxy captures requests without modifying their contents and forwards WebSocket traffic without decrypting it.
