This resource provides cross-browser developer tools for real-time debugging, performance optimization, and code analysis. Key features include visual inspection of CSS animations, network request modification/replay, memory profiling, and accessibility auditing. Tools support protocol-level customization via Chrome DevTools Protocol (CDP) for advanced workflows like automated testing or framework-specific debugging. Recent updates enhance performance tracking with LCP phase analysis and dependency tree insights, while maintaining compatibility with Firefox’s interactive 3D transform visualization and Edge’s network console. Developers can extend functionality through WebExtensions APIs to create custom panels and integrate with runtime environments.
