Toolcraft is an open-source starter kit and UI library designed for building custom AI-powered design applications. It allows users to create small creative products, internal utilities, interactive experiments, and workflow-specific tools, with the only limit being creativity.

Toolcraft provides AI with a structured application architecture rather than just components. It features a functional canvas, toolbar, layer system, timeline, and keyframe workflows. Additionally, it includes embedded AI skills, performance guidelines, and visual testing rules to enhance the quality and consistency of generated creative apps. It is compatible with AI agents like Codex, Claude, and Cursor.

The library offers comprehensive components for various creative workflows, including sliders, panels, timelines, layers, and toolbars, providing all necessary elements to shape visual tools. This enables users to design without limitations.
