Description
Inspect cookies, storage, JWT tokens, and HTTP headers. Inject custom request headers with wildcard URL matching. Request Buddy is a developer tool for inspecting cookies, storage, JWT tokens, and HTTP headers — all from a single popup. FEATURES JWT Token Inspector Automatically detects JWT tokens in localStorage, sessionStorage, and cookies. Decodes the header and payload, and shows whether the token is valid or expired with a countdown timer. Cookie Viewer Browse all cookies for the current site. See domain, path, Secure, HttpOnly, and SameSite attributes at a glance. Filter by name or value. Storage Inspector View and search both localStorage and sessionStorage key-value pairs for the active page. Click any value to copy it to your clipboard. HTTP Header Capture Monitor request and response headers in real time. Filter by request type, method, status code, or URL. Expand any entry to see all headers. Custom Header Injection Create rules to inject custom request headers on matching URLs. Supports wildcard patterns so you can target specific domains, paths, or all traffic. Toggle rules on or off without deleting them. Dark-Themed UI Designed for developers who spend their day in dark mode. Compact 520px popup with tabbed navigation — no new windows, no DevTools panel required. PRIVACY All cookie, storage, and header data is processed locally in your browser. Nothing leaves your device. The extension collects only anonymous install and error analytics via Google Analytics 4 to help improve the product. No personal data is collected.
