Req Analyzer

Req Analyzer is a network debugging tool built for web developers who need to inspect and troubleshoot traffic on the websites and web apps they are building. WHAT IT DOES - Capture network requests and responses on the tab you are inspecting - Inspect URL, method, status, headers, request/response bodies - Hook fetch, XMLHttpRequest, crypto.subtle, and document.cookie at runtime - Take storage snapshots of cookies, localStorage, and sessionStorage - Optional Chrome cookies API snapshot (HttpOnly values are masked) - Filter by search, status, request type (Fetch/XHR, Doc, JS, CSS, etc.) - Generate ready-to-run fetch and cURL snippets from any request - Export sessions as JSON or HAR - Works in both a DevTools panel and a browser side panel - Available in English, 简体中文, 日本語, and 한국어 AI ANALYSIS (BRING YOUR OWN ENDPOINT) This extension does NOT include any AI service. If you want AI-assisted analysis, you configure your own OpenAI-compatible API endpoint (base URL, API key, model). Captured data is sent to that endpoint only when you click "Analyze", and only to the endpoint you provide. The extension has no backend of its own and collects no data for the developer. WHO IT IS FOR Front-end and back-end web developers debugging their own sites — reproducing bugs, understanding API behavior, checking auth/headers, and verifying request flows during development. PRIVACY All captured data stays local in your browser unless you explicitly send it to your own configured AI endpoint. No telemetry, no analytics, no data sold or shared. See the privacy policy for details.
