Overview
Taste Lab is an open-source tool that reverse-engineers the design taste of any website. It uses a four-agent AI pipeline to extract precise measurements, detect patterns, infer design principles, and output a complete design system (colors, typography, spacing, etc.) in both Markdown and JSON formats. It integrates directly with AI coding tools like Cursor, Claude Code, and GitHub Copilot, making it a powerful asset for developers and designers who want to replicate or learn from a website's design language.
WallPreview is a visual mockup generator for wall decor. Artists, poster shops, and galleries can upload an image of their artwork and instantly see it placed in a realistic interior β true to scale, with soft daylight and real shadows. It offers an embed widget for e-commerce stores, a Shopify app, and one-by-one generation for social media and email. The goal is to help buyers visualize how a piece will look in a real room, reducing purchase hesitation.

Pricing
Taste Lab is completely open-source and free to use. However, you need to provide your own Playwright MCP setup (free) and a compatible AI CLI (e.g., Claude Code or Gemini CLI). Those CLI tools may have their own usage costs (e.g., API tokens). There is no paid tier from Taste Lab itself.
WallPreview offers a generous free tier: 2 images per day with no credit card required. The Pro plan unlocks unlimited previews and the embed widget. Pricing is subscription-based (monthly or yearly), and upgrades are prorated. You can cancel anytime, and your Pro features remain active until the end of the billing period.
