Dev Browser is a browser built for mobile web developers. It brings the Chrome DevTools workflow you already use on desktop straight to your phone.
■ Features
• Console REPL — evaluate JavaScript on the current page with $, $$ shortcuts and autocompletion.
• Network Inspector — intercepts fetch, XHR, WebSocket and EventSource traffic with headers, preview bodies, cURL copy, and HAR export.
• Element Inspector — tap any element on the page to see tag, selector, rect, attributes, computed styles, and outerHTML.
• Applications panel — inspect and edit Cookies, Local / Session Storage, Cache Storage, IndexedDB, and Service Worker registrations.
• Request Blocking — block requests by URL pattern (ad domains, trackers, etc.).
• Local Mock Overrides — replace any response with custom status / MIME / body on the fly.
• HAR Export + Bug Bundle — share the network log as HAR 1.2, or a full bundle of screenshot + HAR + console + metadata.
• Network Throttling — Fast 3G, Slow 3G, and Offline simulation.
• Multi-tab browsing with bookmarks and history.
• JS Snippets — save scripts and run them with one tap.
• Bluetooth mouse side-buttons navigate tab history.
■ Privacy
All data lives on-device. Cookies, history, bookmarks, and snippets never leave your phone. The app does not collect analytics or telemetry.
■ Who it's for
Mobile web engineers, QA, and anyone who needs to inspect a WebView-hosted site on a phone without plugging into a desktop.
