Open-source alternatives to WebPageTest.api Nodejs

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

GT is an on-device mobile debugging tool designed to capture network packets, analyze system logs, and profile hardware performance directly on a smartphone. It provides a portable suite of utilities for identifying software bugs and processing bottlenecks without requiring a connection to a host computer. The project features a plugin-based debugging framework that allows for the development of custom functional extensions to implement project-specific debugging logic. It also enables real-time parameter tuning and injection, allowing internal application settings to be modified during execu

Matrix is a suite of mobile application performance management and analysis tools. It provides a plugin-based monitoring system for capturing crashes, lags, and memory leaks, alongside a static binary auditor for reducing installation package size and a bytecode instrumentation tool for performance tracking. The project distinguishes itself through native memory debugging and a SQLite query linter that identifies inefficient database patterns. It employs native interception techniques to detect memory leaks and heap corruption without requiring source code recompilation, and uses a custom run

Exthouse

GodEye is a runtime instrumentation tool and observability framework for Swift mobile applications. It functions as a mobile application debugger and in-process diagnostic overlay, providing a visual interface rendered directly over active applications to monitor metrics and inspect system states without requiring changes to the original source code. The framework enables real-time analysis through a suite of debugging workflows. It captures diagnostic data using method swizzling and system-level hooking to intercept function calls and monitor internal application behavior. The tool covers s

Maplibre GL JS is a WebGL map rendering engine and vector tile map library used to create interactive web maps. It serves as a web-based GIS visualization tool and an interactive map interface framework for rendering geographic data and vector tiles on web pages. The library provides capabilities for 3D terrain rendering and the integration of custom 3D content. It supports complex geospatial data visualization through the use of heatmaps, clusters, and 3D extrusions, while allowing for custom map styling and environmental effect customization. The system covers a broad range of functional a
