real-time collaborative drawing / whiteboard

This project is an AI-powered visual canvas and collaborative whiteboard framework. It functions as a customizable vector drawing engine and a tool for converting hand-drawn interface sketches and wireframes into functional code using artificial intelligence. The system distinguishes itself through the integration of AI agents that can read, modify, and generate visual diagrams directly on the canvas. It also provides a node-based workflow editor for building automation pipelines and data processing flows by connecting multimodal components. The platform covers a broad range of capabilities,

This project is a virtual whiteboard component and vector graphics editor designed for creating diagrams with a hand-drawn aesthetic. It provides a canvas-based drawing engine that can be embedded directly into web applications, allowing users to manipulate shapes, upload images, and export visual data into standard formats like PNG, SVG, or JSON. The platform distinguishes itself through a real-time synchronization layer that supports multi-user collaboration across distributed environments. This engine utilizes end-to-end encryption to secure shared sessions and employs a local-first data p

This project is a programmable, high-performance drawing engine designed for building collaborative whiteboards, diagramming tools, and infinite canvas applications. It provides a reactive graphics runtime that manages complex canvas interactions, viewport animations, and input handling through a unified signal-based API. The framework is built on a schema-driven data store that maintains application state in a strictly typed, centralized record system, enabling efficient UI updates and persistent data management. The engine distinguishes itself through a highly modular architecture that supp

Whitebophir is a collaborative whiteboarding application designed for real-time visual collaboration. It enables multiple users to brainstorm and create content together on a shared virtual canvas using freehand sketching, geometric shapes, and text labels. The platform focuses on private workspace management, allowing the creation of restricted boards via unique URLs and token-based access control to manage editing permissions. It integrates real-time state synchronization for drawing updates and a built-in chat system for text communication between collaborators. The workspace includes too

signature_pad is a JavaScript library and drawing tool for capturing handwritten digital signatures on an HTML5 canvas. It provides a handwriting capture interface that transforms raw mouse or touch inputs into smooth, professional-looking lines. The project uses Bézier curve interpolation to smooth jagged input points into fluid strokes. It supports the configuration of drawing aesthetics, including pen color, background color, and line width, and includes a history management system for undoing and restoring drawing actions. The library handles the serialization of signature data into poin

tui.image-editor is a JavaScript image manipulation library and web-based photo editor. It provides a browser-based interface for cropping, resizing, and applying filters to images using the HTML5 Canvas API. The project is distinguished by its role as a canvas-based annotation tool, allowing users to add text, shapes, and freehand drawings as graphic overlays. It offers extensive UI customization through theme configuration, interface text localization, and the ability to replace default icons with custom SVG files. The library covers geometry manipulation, visual filter application, and im

Quill is a modular, web-based rich text editor designed for structured content authoring. It provides a comprehensive toolkit for building tailored editing experiences, allowing developers to manage document state, handle user input, and synchronize content through a predictable, serializable data model. The editor distinguishes itself through a custom document abstraction that maps the browser DOM to a structured tree of nodes, ensuring consistent behavior across different environments. It utilizes an operational change tracking system that represents all document modifications as a sequence

Rnote is a vector-based note-taking and drawing application designed for capturing handwritten input. It functions as a digital workspace that records stylus pressure and movement to create sketches and notes, storing them as mathematical paths rather than pixels to allow for infinite scaling and non-destructive editing. The application provides a flexible canvas environment that supports infinite scrolling and various page layouts. Users can organize their work using a layer-based system, which allows for the independent manipulation and ordering of individual strokes, shapes, and background

react-canvas is a library for drawing user interface elements to a hardware-accelerated canvas instead of the standard document tree. It provides a system for rendering components to a canvas to improve rendering speed and frame rates. The project includes a layer manager to organize visual elements and cache expensive drawing operations. It features a text engine capable of rendering multi-line text with precise character metric measurements and truncation, as well as a virtualized list system that processes only visible items to maintain smooth scrolling. Interaction is handled through a c

Fabric.js is an HTML5 canvas library and interactive vector graphics engine. It provides an object-oriented model for creating, manipulating, and animating 2D shapes and interactive graphics on a web page. The project functions as an SVG to canvas parser, translating SVG data into interactive canvas objects and exporting canvas states back into SVG format. It also serves as a canvas image processing tool for applying filters, gradients, patterns, and brush strokes to visual elements. The library covers programmatic vector manipulation, including the ability to scale, rotate, skew, and group

Drawnix is a digital whiteboarding and visual diagramming application centered around an infinite canvas. It provides a workspace for freeform sketching, interactive brainstorming, and the creation of structured visual documentation.
