Local AI Design Mockup Tool

Designers need quick UI mockups and wireframes but Claude Design requires web access and subscriptions. This agent skill runs locally in Cursor/Claude Code to generate polished HTML prototypes, mockups, and wireframes without external APIs. Target: designers, product managers, and developers.

The push toward local-first AI tooling is real — privacy concerns and API cost fatigue are driving developers to run models on-device, and Cursor's plugin ecosystem is actively expanding. The closest substitute is v0 by Vercel, which dominates AI-generated UI but requires cloud access and targets a slightly different workflow. At $500–2k/month, the revenue ceiling is low for a standalone product, which makes sense given the niche audience of Cursor users who want offline prototyping — it's a feature, not a platform. The biggest risk is commoditization: Cursor, Claude, and Figma are all racing toward native mockup generation, and a one-person tool in this space has a short window before it's made redundant by a free built-in.
