Howler.js is a JavaScript library that provides a unified interface for managing audio playback across web browsers. It functions as a cross-browser audio engine, abstracting complex browser audio APIs into a consistent developer experience while ensuring reliable performance through automatic fallback mechanisms. The library distinguishes itself by offering specialized tools for spatial audio and efficient asset management. It includes a spatial audio framework that maps three-dimensional vectors to audio nodes for immersive sound positioning, alongside an audio sprite manager that allows de

GSAP is a comprehensive JavaScript animation library designed for orchestrating complex motion sequences and interactive user interfaces. It provides a robust property-interpolation engine that calculates intermediate values for CSS styles, attributes, and numeric properties, enabling smooth visual transitions across web elements. The framework is built on a core architecture that manages animation lifecycles, timeline-based sequence orchestration, and virtual property interception to ensure precise control over motion. The library distinguishes itself through a modular, plugin-based extensib

drawio is a web-based diagramming tool and cross-platform visual designer used for creating flowcharts, network maps, and technical schemas. It functions as a vector graphics editor and an XML-based diagramming engine that allows users to design and export scalable graphics. The software supports a wide range of technical design tasks, including infrastructure mapping for server layouts and the creation of visual aids for technical documentation. It enables the import of diagram files from other tools to facilitate cross-tool migration.

Sharp is a high-performance image processing library for Node.js. It serves as a native extension and wrapper for the libvips framework, providing tools for image resizing, format conversion, and programmatic data manipulation. The project enables the transformation of images into web-friendly formats such as WebP and AVIF while preserving color profiles and alpha channels. It also provides capabilities for generating blank image buffers with specified dimensions and background colors. The library covers a broad range of image manipulation utilities, including rotation, extraction, compositi

This project is a high-level 3D graphics engine designed to render complex, hardware-accelerated environments within web browsers. It provides a comprehensive abstraction layer that manages scene graphs, cameras, and lighting, mapping high-level scene definitions onto low-level graphics APIs. By decoupling these definitions from specific hardware targets, the engine ensures consistent performance across diverse browsers and devices. The framework distinguishes itself through a robust architecture that includes a unified math library for high-frequency spatial calculations and a physically bas

Thumbor is a dynamic image processing service and proxy server that resizes, crops, and filters images on demand via URL parameters. It functions as a URL-based image manipulator that generates specific image versions from source assets to optimize web delivery. The system includes a smart cropping engine that uses facial feature detection and computer vision to automatically center thumbnails on the most relevant visual content. To prevent unauthorized parameter tampering and malicious requests, it employs signature-based request validation and domain-based source whitelisting. Broad capabi

DrawBot is a powerful, free application for macOS that invites you to write Python scripts to generate two-dimensional graphics. The built-in graphics primitives support rectangles, ovals, (bezier) paths, polygons, text objects, colors, transparency and much more. You can program multi-page…

Cura is 3D printer slicing software and a G-code generator that converts 3D models into machine-readable instructions. It provides a management interface for configuring printer profiles and coordinating additive manufacturing workflows. The software includes a multi-extruder print controller for defining multi-material or multi-nozzle hardware setups. It supports custom printer integration by allowing users to define machine dimensions and G-code requirements for hardware not included in default lists. The platform covers remote print management through integration with external print serve

There's a (pretty) new three.js component library for Svelte: threlte website / threlte repo which is (atm) more complete and polished compared to svelthree.

Video.js is a customizable HTML5 video player framework and JavaScript media plugin system. It provides a foundation for rendering and controlling web video playback across different devices and screen sizes, supporting both standard HTML5 integration and adaptive bitrate streaming for live or on-demand content. The project is distinguished by a modular architecture that allows for the extension of playback functionality through a class-based plugin system and middleware-based method interception. This enables the development of tailored media interfaces and the integration of specialized beh
