We checked each of these seven tools against its own website, licence file and code repository in September 2026. Prices change often, so treat them as a snapshot. For the wider picture, see our web design resources guide.
1. Cult UI
What it is. A free library of components you copy into your own project, in the shadcn/ui style: “Accessible and customizable components that you can copy and paste into your apps. Free. Open Source.” It is published by Nolly Studio; its licence names Jordan Gilliam.
Licence and price. The free code is under the MIT licence (“MIT License Copyright (c) 2023 Jordan-Gilliam”). A separate product, Cult UI Pro, sells premium blocks for a one-time “lifetime” payment: $129 on a sale, against $179.
The catch. Pro is not MIT. Its terms give “a non‑exclusive, non‑transferable license”, and “the license is non‑transferable and tied to the purchaser.” They allow Pro blocks in “personal and commercial projects”, but say “You may not publish our code publicly (e.g. open‑source repositories)”, even though the free Cult UI code next to it is MIT.
2. Componentry
What it is. “Animated React components with editable source code. Install via shadcn CLI or your AI editor with MCP.” Its home page lists 52 components, built by one developer, Harsh Jadhav.
Licence and price. Free, MIT (“MIT License Copyright (c) 2026 Harsh Jadhav”). A paid tier is announced: blocks are “coming soon to Componentry Pro”, with no price published.
The catch. It is young (the repository was created in December 2025) and has one maintainer. Its terms say the code is “generally provided under the MIT License unless otherwise specified”, so check each component you use.
3. Refero and Refero Styles
What it is. Refero is a paid library of screenshots from real apps and websites. Refero Styles, marked Beta, lets you “browse 2,000+ AI-readable design systems from leading product websites”: colour, type and spacing notes, as DESIGN.md files, for pasting into an AI coding assistant.
Licence and price. You can “browse and copy any DESIGN.md for free”. Refero Pro costs $17 a month, $120 a year, or $250 as a “one-time payment”; the free plan gives “access to only ~3% of the full collection”.
The catch. Each style is named after a real company. Refero’s own guide says: “You should not ask the agent to recreate ElevenLabs, Linear, Stripe, or any other source exactly.” Refero’s pages we read say nothing about licensing the fonts or the brand a style describes.
4. Taste Skill
What it is. “Open-source skill files that stop Cursor, Claude Code, Codex, Gemini CLI, v0, Lovable, and more from generating generic frontends.” “Taste” in videos most likely means this project (tasteskill.dev), the one by far the most starred on GitHub under that name, but the name alone does not prove it.
Licence and price. Free, MIT (“MIT License Copyright (c) 2026 Leonxlnx”). Its version 2 is labelled “experimental”.
The catch. Its README and its website both carry sponsor offers with tracking links. The README also warns that “Taste Skill has no official token, coin, or crypto project”, so anything selling one is not the project.
5. Impeccable
What it is. “Design guidance for AI coding agents. 1 skill, 24 commands, live browser iteration, and 61 deterministic detector rules for AI-generated frontend design.” It is by Paul Bakaus. We use it on this site.
Licence and price. Free, Apache 2.0 (“Copyright 2025 Paul Bakaus”). “The CLI and browser extension run the deterministic rules with no LLM and no API key.”
The catch. On Claude Code, Codex, Cursor, GitHub Copilot and Grok Build its installer also offers to add hooks, with
yes as the default, and its engine “either sits next to the launcher or is downloaded once on first run into
~/.impeccable/bin/”. For Claude Code, the README warns that “the first edit or Stop event can therefore download and
cache the engine even if the session denies the model’s launcher command”, and advises: “Review installed hooks before
unattended runs”.
6. Playwright CLI
What it is. Microsoft’s browser controller for coding agents: “Playwright comes with playwright-cli, a command-line interface for browser automation designed for coding agents.” Microsoft’s reason for it: “CLI commands avoid loading large tool schemas and verbose accessibility trees into the model context.”
Licence and price. Free, Apache 2.0 (“Copyright (c) Microsoft Corporation.”). It is installed as its own package, @playwright/cli, and was at version 0.1.21 in September 2026, so it is still pre-1.0.
The catch. It is not the same thing as npx playwright test, the command that runs a Playwright test suite. Microsoft’s own pages also disagree on requirements: the README says “Node.js 18 or newer”, the docs page
“Node.js 20 or newer”. Use 20 to be safe.
7. Awesome DESIGN.md
What it is. A collection of DESIGN.md files taken from real websites: “Copy a DESIGN.md into your project, tell your AI agent ‘build me a page that looks like this’”. Its README says DESIGN.md “is a new concept introduced by Google Stitch”. “Awesome Design” in videos most likely means this project; an older, unrelated list called Awesome Design Tools also exists.
Licence and price. The repository is free, MIT (“MIT License Copyright (c) 2026 VoltAgent”). Its companion site, getdesign.md, sells a “Private DESIGN.md” for $34 (shown reduced from $54) and a “Website Starter Kit + DESIGN.md” for $199 (reduced from $299), both one-time.
The catch. The MIT licence covers the files, not the brands. The README says: “We do not claim ownership of any site’s visual identity.”
Left out
A tool named in one video as “Image 23.js” could not be identified. We searched npm and GitHub for the name and close spellings and found no image library by that name, so it may have been misheard.
Our reading
The pattern across most of the seven: a free core, and a catch that sits right next to it. The licence that counts is the one on the exact block or file being copied, not the one on the project’s front page.
