Debug at the speed of Thought.
Production-grade VS Code extension for real-time inspection, debugging, and analysis of modern web apps. The unified developer experience inspired by Flutter DevTools.
Everything you need to Debug.
Eight powerful modules packed into one seamless extension. Zero external libraries, maximum performance.
Component Tree
Experience a live, hierarchical view of your application's React, Vue, or Svelte components with seamless bidirectional synchronization. As your app updates in real-time, the tree reflects every state change instantly. This eliminates the need for manual refreshing and provides a crystal-clear map of your entire UI architecture directly inside your editor.
Component to source
Navigate instantly from your application's user interface directly to the underlying source files via an intuitive point-and-click mechanic. Combine this with our powerful ranked text search engine to find exact definitions effortlessly. Say goodbye to hunting through complex directories; just click the element you want to edit and your cursor is immediately there.
Layout Inspector
Take a deep dive into your application's box models, flexbox containers, CSS grids, and computed properties. The layout inspector visualizes margins, borders, and padding in an interactive, easy-to-understand diagram. It demystifies complex CSS behaviors and ensures your structural styles behave exactly as intended across all viewports.
Prop Editor
Edit component properties and state inline with our robust 3-tier fallback system designed for maximum framework compatibility. Experiment with different data inputs and instantly see the results reflect in the live application preview. This incredibly fast feedback loop allows you to test edge cases without ever leaving your development environment.
Code Coverage
Analyze your codebase with Git-aware coverage tracking that parses Istanbul, LCOV, and Cobertura formats natively. Uncover hidden risk hotspots with line-by-line source highlighting directly in your editor. Trend visualizations help your team understand exactly which files need more testing, ensuring your application remains robust and regression-free over time.
Perf Profiler
Optimize your application's speed with detailed React render tracking, wasted render detection, and timeline KPIs. The profiler hooks directly into the render cycle to show you exactly which components updated and why. Stop guessing about performance bottlenecks and let the data guide your state management optimizations for a lightning-fast user experience.
Network Tab
Intercept fetch and XHR requests natively from the running app with advanced filtering and deep payload inspection. Unlike standard browser dev tools, this inspector isolates the network traffic specific to the components you are actively building. It provides a clean, searchable interface for verifying your API integrations and headers in real-time.
Code Insights
Leverage advanced AI diagnostics to instantly interpret complex stack traces and runtime errors. Instead of just surfacing raw data, Inspectra automatically provides root-cause analysis and actionable code suggestions. This intelligent copilot accelerates your debugging workflow by pinpointing performance bottlenecks and recommending precise state management optimizations.
Debug Paint
Enable powerful visual overlays that immediately highlight component boundaries, render depth, and complex layout constraints. This feature paints your UI with visual indicators that expose hidden styling issues and nested structures. It acts as an X-ray vision mode for your frontend, making CSS and layout debugging remarkably straightforward.
CDP Debugger
Experience full Chrome DevTools Protocol (CDP) integration allowing you to set breakpoints and step through code directly in your editor. Seamlessly inspect local scope, call stacks, and variables without switching contexts. It bridges the gap between Node.js backend logic and browser frontend execution for a truly unified debugging environment.
The Future of Application Intelligence.
We're evolving from an inspector into an AI-powered Engineering Copilot. Here's what is coming next to your workspace.

Framework Support
How it Works.
Inspectra uses a hybrid bridge architecture to deliver zero-lag, frame-accurate inspection.
The Agent
A lightweight IIFE injected into the browser context. It hooks into React/Vue/Svelte internals via devtools hooks and fibers.
The Bridge
A high-performance WebSocket bridge that maintains a typed protocol between the browser and VS Code.
The Dashboard
A rich React UI embedded in a VS Code Webview, providing the unified developer experience.
Multi-Framework by Design.
Inspectra supports the ecosystem you already use.
