# UI UX Pro Max UI UX Pro Max (ui-ux-pro-max) is a skill by Next Level Builder that gives coding agents a searchable design database: UI styles, color palettes, font pairings, UX guidelines and chart types, across stacks from React and Next.js to SwiftUI, React Native and Flutter. Skill · Picked · by Next Level Builder · Works with Claude Code, Cursor, Codex · Updated 2026-10-21 Made by [Next Level Builder](https://nextlevelbuilder.io).

I had to name it in the prompt. - Took twice as long and cost twice as much as the same task without it. - Needs Python 3, since the design search runs as a script. Best for: Starting a new landing page or app screen when you don't have a design direction yet. Skip it if: You already have a design system or a Figma file to build from. ## The test Task (same for both runs): Build a landing page for Streak, a habit-tracking iPhone app. Write it as a single self-contained index.html file in the current directory (inline CSS, no external images). Include a hero, three features, pricing, and a footer. ### Without the skill 1.6 min · $0.37 ![Streak landing page built without the skill: dark background, orange gradient headline, phone mockup on the right](https://www.liorpesoa.com/library/reviews/ui-ux-pro-max/without-desktop.webp) ![Streak landing page built without the skill: dark background, orange gradient headline, phone mockup on the right (phone)](https://www.liorpesoa.com/library/reviews/ui-ux-pro-max/without-mobile.webp) Page: https://www.liorpesoa.com/library/reviews/ui-ux-pro-max/without.html ### With ui-ux-pro-max 3 min · $0.80 ![Streak landing page built with the skill: warm cream background, amber headline, phone mockup with floating cards](https://www.liorpesoa.com/library/reviews/ui-ux-pro-max/with-desktop.webp) ![Streak landing page built with the skill: warm cream background, amber headline, phone mockup with floating cards (phone)](https://www.liorpesoa.com/library/reviews/ui-ux-pro-max/with-mobile.webp) Page: https://www.liorpesoa.com/library/reviews/ui-ux-pro-max/with.html ### What I found - On the first try the skill was installed but never used. The agent wrote the page directly. - When named, it ran its design search and chose an App Store-style page with soft "clay" cards and an amber accent, instead of the default dark theme. - The result had more product detail and nicer rounded buttons, but kept two common signs of AI-made pages: floating cards stacked on the phone mockup (covering its text) and corner gradient blobs with hard, cut-off edges. - The page without the skill was already polished, so the difference is direction and detail, not broken versus fixed. _How I ran it: Claude Code 2.1.306 with Claude Opus, run headless twice with only Claude Code's built-in skills loaded (no user skills, plugins or MCP servers). The second run had ui-ux-pro-max installed in the project and its prompt started with "Use the ui-ux-pro-max skill." Screenshots taken in Chrome at 1440×900 and 390×844 with reduced motion on._ ## What it does - Searches a database of 50+ UI styles, 161 color palettes and 57 font pairings for ones that fit the product you're building. - Applies 99 UX guidelines and reasoning rules for 161 product types, so a dashboard and a landing page get different advice. - Covers 25 chart types and stack-specific guidance for React, Next.js, Vue, Svelte, SwiftUI, React Native, Flutter, Tailwind and shadcn/ui. - Reviews existing UI code for accessibility, consistency and interaction states. ## When to use it Use it at the start of a new page or app, before any components exist, so the agent picks a style, palette and type pairing on purpose instead of falling back to defaults. It's also useful for a review pass on a screen that works but looks generic. ## Questions ### Who made UI UX Pro Max? Next Level Builder.
