Toolcraft is an open-source starter kit and UI library for building custom design apps with AI. Use it to create branded asset generators, explore new visual styles and turn repetitive design tasks into reusable tools.

It works with any AI agent (Codex, Claude, Cursor). MIT Licensed. 100% Free.

What can you build:

Toolcraft works best for apps that combine a visual canvas with a focused set of controls, such as:

• Procedural graphics and gradient generators

• Image stylization, ASCII, pixel, halftone, and glitch effects

• Shader and Three.js experiments

• Animation and video-effect tools

• Blog cover and branded asset generators

What Toolcraft includes

• A starter app built with TanStack Router, React, TypeScript, Tailwind CSS, and Base UI

• A canvas with the familiar pan and zoom controls you’d expect from a design tool

• A component library with buttons, dropdowns, sliders, font pickers, color palettes, curve editors, image uploaders, and more

• Built-in layers, animation timelines, and keyframes that your agent can turn on as your app needs them.

• Image and video export workflows

• An AI harness that gives your agent the skills, instructions, and checks to build on Toolcraft’s design system.

• Unit, browser, acceptance, and performance checks

• All the code behind your app, ready to customize with your AI agent
