Which one should you choose?

Both products are good at what they do. Pick the one that matches how you actually work — these are the honest cases for each side.

HorizonX

When to choose HorizonX

  • You want Figma files and production code from the same source, covered by one subscription instead of separate one-time kits.
  • You work with AI coding tools and want a library that ships new components and drops every month, not just a static release.
  • A monthly subscription fits your cash flow better than a large one-time purchase, and you value the interactive tools that come with the catalogue.
  • You ship client work and want the commercial license included rather than as an add-on decision per kit.

Untitled UI

When to choose Untitled UI

  • You are a Figma-first designer who wants the single deepest Figma kit and design system — 10k+ components and variants, 900+ global styles and variables, 420+ page examples.
  • You prefer one-time pricing with lifetime updates and unlimited projects over any subscription.
  • You want a React library built on React Aria for accessibility plus Tailwind CSS, with a free open-source component tier to start from.
  • Your team standardizes on a static kit and updates it on your own cadence rather than consuming monthly drops.

Frequently asked questions

  • Not exactly. Both sell premium interface assets for design and development, but Untitled UI sells two one-time kits — a Figma UI kit and a React component library — while HorizonX is a subscription catalogue that mixes Figma files, production React/Tailwind components and interactive tools, with new drops every month.

  • They price differently, so “cheaper” depends on how long you use them. Untitled UI is a one-time purchase: Figma from $129 and React from $349 for a single-user license (as of Sept 2026). HorizonX is a recurring subscription with Starter, Pro and Max plans. If you want one kit and never update, a one-time price can win; if you want ongoing drops across design and code, a subscription spreads the cost. Exact HorizonX pricing is on our /pricing page.

  • No — the Figma kit and the React library are separate products with separate purchases. The React docs note the paid kit stays “synced with Untitled UI Figma”, but you buy the design files and the code library independently. HorizonX includes Figma and code formats under one subscription.

  • Yes, both allow commercial client work. Untitled UI’s paid kits are a single-user license for use in unlimited projects, and its free React components are open-source. HorizonX includes a commercial license in every paid plan.

  • Both position themselves for AI workflows: Untitled UI publishes AI kits for Lovable and bolt.new and open-source React components you can paste, while HorizonX is built for the vibe-coding era with design-and-code packages that give AI agents coherent constraints. Try both against your actual agent — the best one is the one whose output stays consistent in your stack.
