Flowy
The minimal javascript library to create flowcharts
flowy is a minimal JavaScript library for building interactive flowchart-style interfaces in web applications, allowing developers to create node-based editors, automation builders, or visual programming tools with relatively little code. It provides draggable, connectable blocks (nodes) that can be placed on a canvas, connected via lines, and rearranged dynamically while preserving the underlying graph structure. The library focuses on simplicity and aesthetics, offering a clean look out of the box that can be customized with your own CSS, making it suitable for dashboards, SaaS products, or internal tools. Events emitted by flowy enable integration with your own data model, so you can sync block positions, connections, and metadata back to a database or application state. ... -

glfx.js
An image effects library for JavaScript using WebGL
glfx.js is a JavaScript image-effects library that uses WebGL to apply real-time filters and transformations directly in the browser. It exposes a simple API where images are uploaded into GPU textures, processed with shader-based filters, and rendered to a WebGL canvas. Because the work is done on the GPU, many effects that would be too slow in pure JavaScript (like complex blurs, lens effects, or tilt-shift) can run interactively, even on large images. The library is structured around three components: textures (image sources), filters (shader pipelines), and canvases (render targets), making it easy to compose multiple effects. ... -

jeelizFaceFilter
Javascript/WebGL lightweight face tracking library
This JavaScript library detects and tracks the face in real time from the camera video feed captured with WebRTC. Then it is possible to overlay 3D content for augmented reality applications. We provide various demonstrations using main WebGL 3D engines. We have included in this repository the release versions of the 3D engines to work with a determined version (they are in /libs/<name of the engine>/). This library is lightweight and it does not include any 3D engine or third-party library.... -

JavaScript Load Image
Load images provided as File or Blob objects or via URL
JavaScript-Load-Image is a client-side image loading and processing library that focuses on turning File/Blob objects or remote URLs into HTML <img> or <canvas> elements, optionally transformed in the process. It is often used in upload flows where images need to be previewed, resized, rotated, or cropped before being sent to a server, reducing bandwidth and improving user experience. The library can interpret image metadata, including Exif and IPTC tags, and can extract embedded thumbnails when present, which is handy for building fast image pickers or galleries. ... -

Awfice
The world smallest office suite
Awfice is an experimental office suite made from extremely small browser applications written in plain JavaScript. It includes a rich-text editor, spreadsheet, drawing canvas, and presentation maker. Every main tool is under one kilobyte and is compressed into a single line of code. The applications can run directly from data URLs, bookmarks, or saved HTML files without installation. They work offline and intentionally avoid persistent storage, so refreshing the page erases the current content. The spreadsheet supports formulas and cell references, while the presentation tool offers editable slides and formatting shortcuts. ... -

RecordRTC
RecordRTC is WebRTC JavaScript library for audio/video
RecordRTC is a client-side JavaScript library for recording browser media streams. It can record audio, video, screen activity, canvas animation, and combined media sources through WebRTC-related browser APIs. The library supports common modern browsers across Windows, macOS, Linux, Android, and selected iOS or Safari use cases. Developers can use promise-based or callback-based recording flows, then retrieve blobs for saving, uploading, or playback. It offers multiple recorder strategies, MIME type options, time-sliced blob delivery, CDN usage, npm installation, and many demos. ... -

MaLiang
iOS painting and drawing library based on Metal
MaLiang is a painting framework based on Metal. It supports drawing and handwriting with customized textures. The name of "MaLiang" comes from a boy who had a magical brush in a Chinese ancient fairy story. A Canvas is the basic component of MaLiang. You will paint all things on it. Canvas extends from MetalView, which extends from MTKView. MetalView handles all the logic with MetalKit and hides them from you. MaLiang supports the automatic adjustment of stroke size with painting force. 3D Touch is supported by default, and simulated force will be setup on devices that do not support this. forceSensitive is the property that force affects the stroke size. ... -

Face-Detection-JavaScript
Small browser-based computer vision demo
...It loads face detection, facial landmark, face recognition, and facial expression models from a local models folder. Once the webcam stream starts, the app creates a canvas overlay and draws detection results directly over the video feed. It can identify face boxes, map facial landmark points, and display detected expressions in near real time. The project is simple enough for beginners to study, but it still demonstrates the core pieces needed for webcam access, model loading, detection loops, result resizing, and canvas rendering. ... -

WebGL Heatmap
A high performance WebGL/JS heatmap display library
webgl-heatmap is a browser-side rendering library that uses the GPU via WebGL to draw smooth, continuous heatmaps from large numbers of data points. Instead of relying on CPU-bound canvas operations, it leverages fragment shaders and additive blending to accumulate intensity and colorize results in real time. The API lets you push points or weighted samples into a buffer and then renders a gradient map where hot areas emerge organically from density rather than discrete markers. Because most work happens on the GPU, it scales well as the number of points grows and remains interactive for animations, live telemetry, or dynamic overlays. ... -
