Mearl

Agent-driven browser toolkit: automation, verification, observability

Mearl is a browser extension for inspecting webpages, debugging requests and verifying page behavior. Use it to edit long links, explore structured data and handle QR codes, or investigate network activity while developing and testing a website. Links and structured data View a URL as protocol, host, path and query fields. Read decoded parameters, edit individual values and copy the resulting link. Format JSON, expand nested data, search fields and copy content. Generate a QR code for a link or recognize a code in a webpage image through the context menu. Network and page debugging Inspect request headers, parameters and responses, with filtering, search and preserved records. Edit and resend a request to compare results. Use mock responses to test complete payloads, individual fields, delays or streaming behavior. Redirect or block requests, rewrite headers, inspect console logs and check tracking events and their related page elements. Mobile and automated verification After configuring real-device capture, inspect mobile network traffic and simulate responses. With the companion browser-control tools configured, an AI assistant can read pages, fill forms, manage tabs, upload files and take screenshots, then check the resulting page changes. The companion tools also support mobile viewport and timezone simulation, action recording and separate browser environments. Getting started Use the toolbar popup for quick tools, the developer-tools panel for debugging, or the side panel for assistant chat. The interface supports English and Simplified Chinese, dark mode and adjustable font size. Link, data and QR tools are available after installing the extension. Automated control requires companion tools, and real-device capture requires additional setup. Workplace integrations require the corresponding account, network access and permissions. Response translation depends on the browser's built-in AI availability. Documentation: https://mearl.alibaba-inc.com
