Endless tools
Endless Tools is a browser-based, no-code platform to generate 3D visuals, animations, effects and other graphic assets without heavy software or coding, using features like AI object creation, vector-to-3D conversion, material libraries, shaders and embed-ready interactive elements.

Gradientor
by Afterimage
A simple and fun tool for drawing with gradients.

Marbling
by Afterimage
In-browser marbling simulator. Marble your pictures!

Color Wheel
by Adobe
Browse and create colour themes based on colour theory with the palette generator. Extract themes from images, generate gradients and recolour vector artworks.

Dither Tool
by Razi Ansari
A web-based creative utility built with Three.js and Figma Make, designed to let users upload and transform 3D models (OBJ, GLTF/GLB formats), videos (MP4, MOV, WebM), and raster images (PNG, JPEG, etc.) into stunning dithered and ASCII art visuals.

Ouroborus
by Dia.TV
Researching the possibilities of self-referential shaders. A playground for exploring the effects of recursive feedback loops in real time.

Contrast Checker
by WebAim
The OG online tool to evaluate the accessibility of colour combinations by calculating contrast ratios between foreground and background colours. Users can input HEX values to see whether they meet WCAG standards for normal, large, and enhanced text.

Contrast Checker
by Coolors
A simpler and pretier contrast checker (but not as complete as WebAim's).

Contrast Grid
by Michael Herchel
Visualise the contrast ratios of multiple colour pairings at once by generating an easy‑to‑read grid of foreground and background combinations and their WCAG accessibility results.

Coloring for Colorblindness
by David Nichols
Certain colours that look different to people with normal vision may appear identical to someone who is colourblind, following predictable “confusion lines” in colour space. This website simulates that effect, showing how your chosen palette would appear to viewers with protanopia, deuteranopia, or tritanopia.

Who Can use
by Corey Ginnivan
A tool that simulates how colour contrast can affect people with different visual impairments.

Typeflow
by Algo.tv
This free tool runs on Cavalry, a popular animation software — it's meant to showcase how Cavalry can be used to build tailor-made, branded creative tools. The preview runs on the Cavalry WebPlayer. Most of these scenes are available for download for free from Scenery, a community of artists sharing open files.

BlobSketch
by Colin Reid
BlobSketch is a realtime, browser-native soft-body laboratory where drawing becomes a dialogue with physics. Built in under 150KB of pure HTML, CSS, and WebGL, it reframes physics engines as creative instruments, demonstrating how embodied soft-matter interfaces can support both scientific insight and artistic exploration.

Video2Vision
By Vera Vasas, Daniel Hanley
An open source image processing toolkit for using multispectral videos to approximate the vision of animals. Created by biology researchers, to be used in conjunction with a 3D printed open source device called Multispectrum Beamsplitter.
