macSVG - An open-source macOS app for designing HTML5 SVG (Scalable Vector Graphics) art and animation with a WebKit web view ➤➤➤

Fabric.js is an object-oriented canvas library that provides an interactive framework for managing shapes, images, and text within an HTML5 canvas environment. It abstracts raw pixel-based drawing commands into a structured hierarchy of objects, enabling developers to manipulate, transform, and animate elements through a centralized event-driven system. The library distinguishes itself by offering comprehensive state serialization, allowing complex graphic compositions to be converted into JSON or SVG formats for persistent storage and reconstruction. It includes a built-in SVG parser that co

OctoPrint is a web-based control panel and Python-based hardware server for managing 3D printers. It functions as a G-code remote controller that sends commands to printer firmware over a persistent USB serial connection, allowing users to operate hardware and monitor print jobs through a browser. The project is an extensible hardware management platform that utilizes a plugin-based system. This architecture enables the addition of third-party functionality and custom extensions to modify core behavior and expand the system's remote control capabilities. The platform covers remote printer ma

FreeCAD is an open-source engineering design suite designed for parametric 3D modeling, architectural planning, and mechanical assembly. It functions as a professional-grade platform that utilizes history-based operations to allow for non-destructive design updates, enabling users to construct complex geometry through a sequence of constrained sketches and solid operations. The platform distinguishes itself through a highly modular, workbench-based architecture that allows users to tailor the interface and toolsets to specific engineering domains. It features deep Python integration, which se

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

A Paint app, targeting Desktop, built proudly with Flutter 💙. You are welcome to contribute and make features requests or file Issues.

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
