js-beautify is a web language beautifier and code formatter designed to standardize the layout and structure of JavaScript, HTML, and CSS files. It reorganizes source code into a consistent, readable style by applying configurable indentation and spacing rules. The project includes a utility for unpacking minified scripts, which transforms compressed or obfuscated JavaScript into a human-readable format. It provides a command-line interface for executing bulk code reformatting across multiple files. The tool supports customizable formatting rules and language-specific overrides, which can be

This project is a web framework performance benchmark suite and automated benchmarking orchestrator. It serves as a multi-language performance analysis tool designed to measure execution speed, throughput, and latency across various HTTP libraries and programming ecosystems. The system functions as an HTTP framework comparison tool that evaluates relative efficiency using consistent hardware and request patterns. It automates the build, deployment, and execution cycles necessary to collect stable performance data and compute metrics such as error rates and latency percentiles. The suite eval

jscpd is a code duplication detector that scans source code across 223 languages to find identical or near-identical copy-pasted blocks using a rolling hash algorithm. It is built with a Rust core for high performance, exposed through a Node.js API and CLI, and can be run as a standalone binary with no runtime dependencies. The tool detects duplicates in embedded languages within Vue, Svelte, Astro, and Markdown files by tokenizing each language block separately, and it supports extensionless scripts via shebang detection. The project distinguishes itself through its integration capabilities

Spotless es un orquestador de formateo multilenguaje y plugin de Gradle que automatiza el estilo de código en varios lenguajes de programación dentro de un único pipeline de construcción. Funciona como un coordinador para múltiples formateadores de terceros, una herramienta de linting de estilo de código y un sistema para insertar y actualizar encabezados de licencia estandarizados. El proyecto se distingue por la aplicación de estilo integrada en git, utilizando hooks de pre-push y referencias de git para aplicar el formateo solo a archivos o líneas modificadas. Admite configuraciones de construcción compartidas, permitiendo que las reglas de formateo se distribuyan y carguen en múltiples proyectos mediante artefactos remotos para mantener una única fuente de verdad. La herramienta cubre una amplia gama de capacidades, incluyendo la transformación de texto de código fuente mediante expresiones regulares y parches JSON, gestión de importaciones y estandarización de espacios en blanco. Se integra con una amplia gama de binarios y herramientas externas para lenguajes como Java, Python, Kotlin, C++, Go y TypeScript. La funcionalidad adicional incluye la verificación de formateo para garantizar la idempotencia y la optimización incremental para omitir archivos sin cambios.

dprint is a multi-language code formatter that applies consistent styling across various programming languages using a pluggable architecture. It functions as a unified project style management tool, a command-line interface for continuous integration style enforcement, and a Language Server Protocol implementation for real-time formatting in editors. The project is distinguished by a WebAssembly-based plugin system that loads sandboxed formatting logic from URLs or file paths. It further extends its capabilities through a process-based tool integration that wraps external command-line interf
