Start a new project with a single npx command and get an opinionated architecture that an AI agent can extend without losing structure.
Working canvas, toolbar, layer system, timeline and keyframe workflows are already wired up, so generated apps feel like real design tools rather than demos.
Sliders, colour palettes, gradient and curve editors, font pickers and more are included, covering the controls most creative tools need.
