ios-webkit-debug-proxy is a command-line proxy that bridges Chrome DevTools to Safari Web Inspector on iOS devices, enabling remote debugging of web content over USB. It translates WebKit remote debugging protocol messages into Chrome DevTools Protocol over persistent WebSocket connections, allowing developers to use Chrome DevTools, Safari Web Inspector, or Firefox DevTools to inspect and debug web content in MobileSafari and UIWebViews on real and simulated iOS devices. The proxy discovers and communicates with iOS devices over USB using the libimobiledevice library without requiring iTunes

Lighthouse is an automated diagnostic tool that evaluates web pages against industry standards for performance, accessibility, and search engine optimization. It functions as a programmatic analysis engine and a command-line utility, allowing developers to integrate comprehensive web quality checks directly into continuous integration pipelines and local development workflows. The project distinguishes itself through a modular architecture that utilizes artifact-based data collection to ensure consistent analysis across different environments. It supports a headless execution mode for automat

Lighthouse CI is a continuous integration tool designed to automate web audits and detect performance, accessibility, and SEO regressions between code commits. It functions as a web performance regression suite that enforces resource budgets and runs automated quality checks during the software development lifecycle. The system distinguishes itself through the ability to block code merges if performance metrics fall below defined quality thresholds. It provides mechanisms for commit-to-commit comparison and cross-version site analysis to pinpoint specific resource improvements or regressions.

This project is a web performance monitoring library designed to collect, calculate, and attribute user experience metrics. It functions as a real user monitoring tool that tracks core loading and interactivity metrics from actual browser sessions to quantify website health and identify speed bottlenecks. The library includes a performance attribution engine that collects diagnostic data to pinpoint the root causes of page lag. This allows for the identification of specific performance bottlenecks alongside the measurement of core web vitals. The system provides comprehensive data export cap

Chuck is an in-app network debugger and HTTP traffic logger for Android applications. It intercepts and records outgoing requests and incoming responses for OkHttp clients, providing an interface to monitor network activity and debug API interactions directly on a mobile device. The tool enables the inspection of network traffic through gzip decompression of compressed payloads and a search utility for filtering transactions by request paths or response codes. Captured interactions can be exported to external applications using the Android system share intent. The system manages data using l

Speedscope is a web-based performance profiler that visualizes profiling data through interactive flamegraphs and timeline views. It ingests performance profiles from a wide range of sources, including Chrome, Firefox, Safari, Node.js, .NET Core, Instruments, Hermes, GHC, and Ruby, normalizing them into a common schema for unified analysis. The tool distinguishes itself with a canvas-based rendering engine that draws flamegraphs without DOM nodes for each frame, and a WebAssembly-based rendering pipeline for high-performance drawing. It offers left-heavy stack sorting to surface the most time
