Toolcraft

Toolcraft is a free, open-source starter kit and UI library for building custom design applications powered by AI. Whether you are creating a drawing tool, an editor, or a creative workflow app, it gives you a solid foundation to start from instead of building everything from scratch.

It comes with a ready-made application architecture for creative tools, including a canvas, toolbar, layers panel, timeline, and keyframe workflows, so you get the essential building blocks of a professional design app out of the box.

Built-in AI skills, performance instructions, and visual testing rules are designed to help AI agents generate more consistent and reliable creative apps, reducing the trial-and-error usually involved in getting AI-generated code to work well.

Toolcraft works with Codex, Claude, Cursor, and other AI agents, letting you pair the toolkit with the coding assistant you already use.
