DevLensPro is a Chrome extension designed as a bridge between your browser and Claude Code, offering an intuitive Claude Code debugging workflow. It is built for developers who use Claude Code for AI-assisted development and need a faster way to communicate UI issues. The core value is eliminating the tedious back-and-forth of describing UI bugs by allowing users to simply point at an element and let Claude fix it automatically. This tool integrates directly with Claude Code via the Model Context Protocol (MCP), making it a seamless addition to any AI-coding setup. With a single Option+Click, developers can capture rich context including screenshots, CSS selectors, and even React component information, which is instantly relayed to Claude Code. This transforms the debugging process from manual description to instant visual communication.
The primary pain point DevLensPro addresses is the friction developers face when trying to explain UI bugs to an AI assistant. Normally, describing an element's position, styling, and behavior requires verbose text or multiple screenshots, often leading to misinterpretation. This slows down debugging and interrupts flow. DevLensPro solves this by capturing exactly what you see: the CSS selector, computed styles, text content, position, and even console logs. Claude Code receives this complete context instantly, enabling it to locate the exact code and apply fixes without ambiguity. For teams using Ralph autonomous agent, this means bugs can be fixed fully autonomously.
The Chrome Extension is the primary interface for DevLensPro. After installing in Developer Mode, users can Option+Click any UI element to trigger a capture. This action collects the HTML element details, a full-page screenshot with the element highlighted, console logs, computed CSS styles, and React component data via Fiber inspection. All this data is sent to Claude Code through the MCP Protocol, which provides a native integration without additional setup. The MCP server runs locally on port 7007 and uses a WebSocket connection for real-time sync. This means as soon as you click, Claude Code receives a task with full context, ready to analyze and fix.
DevLensPro is compatible with Ralph, an autonomous agent that can execute tasks within Claude Code. When Ralph is active, pointed elements trigger not only context capture but also autonomous bug fixing and feature development. Ralph receives the task via MCP and can independently locate the code, make changes, and even create pull requests. Additionally, DevLensPro detects React components by inspecting Fiber internals, providing the component name and source file path. This is invaluable for projects using React or Next.js, as it tells Claude exactly which file to edit. Together, Ralph and React detection enable hands-free debugging for modern frontend stacks.

Beyond basic element capture, DevLensPro includes an AI Enhance feature for task descriptions. When you type a vague comment like 'button looks weird', clicking AI Enhance generates a structured, detailed task description covering alignment, spacing, and CSS issues. This improves Claude's accuracy. Another essential feature is console log capture. Every click grabs errors, warnings, and logs from the browser console, giving Claude immediate insight into JavaScript issues affecting the UI. Combined with computed styles and full-page screenshots, Claude has a complete picture of the problem. These capabilities make DevLensPro not just a debugger but an intelligent UI inspector.
The workflow is straightforward: install the Chrome extension, run the MCP configuration command (e.g., `npx -y @devlenspro/mcp-server install`), and start pointing. Each Option+Click creates a task linked to the page URL. DevLensPro uses URL-based project management to map URLs to local project folders, so Claude automatically knows which codebase to edit. The captured data includes a CSS selector, tag name, computed styles, inner text, position, and React component info. This is sent via WebSocket to Claude Code's MCP server. Claude then analyzes the element, locates the corresponding code, and can either suggest a fix or, with Ralph, autonomously implement and validate it. The entire process from click to fix takes about 30 seconds.
In practice, DevLensPro accelerates several developer workflows. For quick debugging, a developer can point at a misaligned button, describe the issue, and Claude applies a fix within 10 minutes. For new features, users can point at existing UI for context and let Claude scaffold new components with Ralph's help, completing in 2-8 hours. For full project development, Claude understands the entire codebase through element inspection and can handle complex refactoring in 1-2 days. The tool also saves hours every week by eliminating the need to type verbose bug reports. Playwright validation is included for Pro users, ensuring fixes pass tests. The result is up to 10x faster debugging workflows and 100% context accuracy.
DevLensPro is aimed at frontend and full-stack developers who use Claude Code, as well as teams practicing AI-assisted coding. It supports Chrome browser and integrates with Claude Code, Cursor IDE, and Windsurf via MCP configuration commands. The tech stack is purely local, with optional cloud mode for remote VPS setups. Pricing offers a Free tier with 5 tasks per month and one project, and a Pro plan at 9.99€/month (50% off early adopter) with unlimited tasks, cloud mode, React detection, and priority support. The token-based access via Clerk ensures privacy, and no data is stored on servers. DevLensPro is free and open source, reinforced by its core value: making Claude Code debugging visual, instant, and autonomous.
DevLensPro is designed for frontend and full-stack developers who use Claude Code for AI-assisted development. It is ideal for UI engineers debugging React or Next.js applications, quality assurance engineers automating bug reporting, and AI-coding enthusiasts building agentic workflows. Professional developers working on local or remote VPS setups will benefit from the privacy-first, token-based pricing. Teams using Ralph for autonomous development will find DevLensPro essential for bridging browser and terminal. It also suits anyone practicing AI-assisted debugging who wants to eliminate manual context switching and accelerate their workflow.
