TanStack Query DevTools is the essential debugging companion for developers using TanStack Query in their web applications. This powerful Chrome DevTools extension provides deep insights into your application's data fetching, caching, and state management, making debugging and optimization effortless. Whether you're building with React, Vue, Svelte, Angular, or vanilla JavaScript, this extension works seamlessly with any framework that uses TanStack Query Core.
The extension integrates directly into Chrome DevTools as a dedicated panel, automatically detecting TanStack Query usage and providing real-time monitoring with minimal setup. You'll see all your queries and mutations in a professional two-column layout with instant status updates, making it easy to understand what's happening in your application at any moment.
Key Features:
• Real-time query monitoring with live status indicators showing loading, success, error, and stale states • Interactive cache inspection with detailed JSON data exploration and syntax highlighting • Complete mutation tracking with historical view of all operations performed during your session • One-click debugging actions including query refetching, cache invalidation, and manual removal • Loading state simulation and error injection for comprehensive testing scenarios • Professional dark and light theme support with automatic system detection • Fast search and filtering capabilities across all queries and mutations • Zero performance impact on your applications when DevTools are closed
Perfect for frontend developers, full-stack engineers, QA teams, and anyone working with data-driven applications. The extension eliminates time-consuming console debugging sessions and helps you identify performance bottlenecks instantly. You'll understand complex query dependencies and cache behavior at a glance, reducing debugging time from hours to minutes.
Setup is straightforward: install the extension, then expose your query client by setting `window.__TANSTACK_QUERY_CLIENT__` to your TanStack Query client instance in your application. Once configured, open Chrome DevTools and a new "TanStack Query" tab will appear, giving you immediate access to powerful debugging capabilities.
The extension operates entirely locally in your browser with zero data collection, ensuring your privacy and security. All debugging happens on your machine without any external network requests, making it safe for use in any development environment.
Whether you're troubleshooting a production issue, optimizing query performance, or onboarding new team members, TanStack Query DevTools provides the visibility and control you need to build better applications faster.
