Singapore Government Design System vs UI Prep Design System

Singapore Government Design System (SGDS) is a shared toolkit for teams creating digital services for Singapore government. Its foundations cover colour, typography, spacing, and design tokens, alongside interface components such as buttons, tabs, forms, cards, and tables. Templates combine foundations, components, and utilities into reusable page layouts; blocks are reusable sections that teams can compose into templates and product experiences. SGDS v3 supports sub-brands and agency-specific requirements while retaining a shared government identity. Developers can install the web component package with npm, pnpm, yarn, or bun. The guide includes integration instructions for React, Vue, Angular, and Next.js, but utility classes require Tailwind CSS v4. GovTech Figma Enterprise users can enable SGDS v3 libraries, while agencies outside GovTech and partners can access the UI Kit through Figma Community. Components are designed to meet government accessibility standards by default. The system also provides guidance and agent skills for AI tools. All .gov.sg digital services must adopt the Official Government Banner and Global Footer. SGDS is free and open source.

UI Prep Design System is a Figma kit for building interfaces with reusable components, variables, and styles. Figma Variables organize primitive and semantic colors, spacing, sizing, and corner radius. One-click light and dark modes support a multi-brand setup. Components use Auto Layout, variants, properties, exposed nested instances, and interactive prototyping features. The maker says the kit meets WCAG 2.1 contrast ratios and uses an 8pt base unit. Primitive color variables can update semantic variables; number variables change component sizing and spacing; text styles can be updated with the Batch Styler plugin. The Free Demo costs nothing. Individual costs $99, paid once, and Team costs $199, paid once. A free Figma account is sufficient, but using the kit as a Figma library requires Team Library on a paid Figma plan. The license permits customized commercial, client, and personal projects.
