Feature Comparison
Pros & Cons
Untitled UI
Pros
- Massive component library with 10,000+ variants covering virtually every UI pattern
- One-time payment with lifetime updates — no recurring subscription fees
- React components built on modern stack (React 19.1, Tailwind CSS 4.1, TypeScript 5.8, React Aria)
- Full Figma variable support including dark mode, spacing, radius, and typography variables
- Free tier available for both Figma and React to evaluate before purchasing
Cons
- Figma-centric — designers using Sketch, Adobe XD, or other tools cannot use the Figma kit
- React-only component library — no support for Vue, Angular, Svelte, or other frameworks
- Large file size of the full PRO kit may slow down Figma performance on lower-end machines
- Per-seat licensing for teams means costs scale with team size
Sketch
Pros
- Full offline functionality — design without internet on your Mac with no compromises
- Free developer handoff — invite unlimited developers to inspect, export, and grab CSS at no extra cost
- Privacy-first approach with minimal analytics, no cookies, no tracking in documents
- Open file format prevents vendor lock-in, making migration to other tools straightforward
- Guest editors who already pay for Sketch don't add to your team's costs
Cons
- macOS only — no Windows, Linux, or browser-based design editor available
- No free plan available, only a free trial to get started
- Smaller plugin ecosystem compared to Figma's community
- Limited AI features by deliberate choice, which may lag behind competitors adopting AI design tools
Our Verdict
Both Untitled UI and Sketch are excellent choices with similar feature sets. Your decision should depend on your specific needs, pricing, and whether you need self-hosting capabilities.
