What it is ​

Tailark is a shadcn/ui registry of marketing-site sections, full pages and decorative illustrations, built with Next.js and Tailwind by Méschac Irung. There are two namespaces. @tailark-oss serves the free kits and needs no account; at review its registry index held 259 items, including 150 blocks and 10 pages. @tailark serves the paid Quartz kit behind an API key. Quartz comes in several visual styles (Dark, Grid 1, Grid 2 and Libre) and covers hero, feature, pricing, testimonial, logo-cloud, FAQ, footer and auth sections. It also has whole pages: product, solution, about, brand, contact, wall of love, blog and legal. Every item ships in two builds, Base UI (the default) and Radix UI.

When to open it ​

When a SaaS or startup site needs calm, well-spaced sections that already match each other, and you want to install them into a shadcn project rather than copy markup. The free kits are enough for a full landing page. Quartz is worth a look when you also need the secondary pages that templates usually skip, such as legal, brand or customer-story pages.

Most useful ​

  • Dusk kit (free): 10 landing pages and 39 blocks, rebuilt in July 2026 according to the changelog.
  • Mist and Veil kits (free): section sets for hero, features, pricing, stats, team, integrations, comparison tables, login and sign-up.
  • Quartz pages (paid): legal index and document pages driven by MDX, contact-sales layouts, wall-of-love pages and brand-guideline pages with logo downloads.
  • Illustrations: decorative TSX components for bento and feature cards, so there are no image files to manage.
  • Snippets: variant sets of core pieces such as buttons, shown in several layouts and states.

Using it with agents ​

Add the namespace to components.json and install by name, for example npx shadcn@latest add @tailark-oss/dusk-hero-section-one. The UI base is picked by URL path (/r/ for Base UI, /r/radix/ for Radix). Paid items need an API key from the dashboard. The docs include a setup prompt generator that writes an AI prompt or a ready components.json for your plan, kit and base. @tailark is listed in the official shadcn directory, so the shadcn MCP server can find it. The free @tailark-oss namespace has to be added to components.json by hand. No llms.txt was published (404 at review).

Watch out for ​

  • The two namespaces changed meaning in July 2026 (@tailark now means paid Quartz), so older tutorials may point at the wrong one.
  • The paid licence terms live only in the pricing FAQ. There is no separate licence or terms page (both returned 404).
  • The shadcn directory's health check marked the @tailark entry as degraded at review because sampled items failed validation (it points at the keyed namespace).
  • Account sharing is not allowed, and the free-kit exception for derived kits does not cover Quartz.

Reusable ideas ​

  • Split a registry into a public namespace and a keyed namespace, so free and paid installs use the same command.
  • Ship decorative illustrations as components, so a feature card needs no asset pipeline.
  • Offer the pages a real company needs after launch (legal, brand, contact sales), not just the landing page.
  • Generate the project setup from a short form (plan, kit, base) instead of long written instructions.
