The best design system examples are useful because they show more than a component library. They show how a company turns product decisions into reusable foundations, components, patterns, content rules and implementation guidance.
A mature design system reduces repeated decisions. Designers know which component to use, engineers know how it behaves, and product teams can reason about new features without reinventing the interface each time.
Below are eight design system examples worth studying in 2026.
Design system examples at a glance
| Design system | Company | What to study |
|---|---|---|
| Material Design | Foundations, components, motion and cross-platform guidance | |
| Human Interface Guidelines | Apple | Platform-native interaction principles |
| Carbon | IBM | Open-source enterprise design and code libraries |
| Lightning Design System | Salesforce | Enterprise application patterns |
| Polaris | Shopify | Commerce-focused product guidance |
| Atlassian Design System | Atlassian | Tokens, components and content standards at scale |
| Primer | GitHub | Design tokens and product UI for developer tools |
| Fluent | Microsoft | Cross-platform productivity experiences |
1. Google Material Design
Material Design is one of the most influential public design systems. It combines visual foundations, components, interaction guidance and theming into a system that can work across a large family of digital products.
What to learn: a design system is more useful when components are backed by clear principles and behavior guidance, not only Figma assets.
2. Apple Human Interface Guidelines
Apple’s Human Interface Guidelines organize design guidance around foundations, patterns, components, inputs and platform technologies.
The important lesson is platform fit. An interface should not only look consistent with the brand; it should behave in ways users already understand on the device they are using.
What to learn: define interaction conventions and platform behavior alongside visual rules.
3. IBM Carbon Design System
Carbon is IBM’s open-source design system for digital products. It includes design guidance, tokens, Figma resources and code libraries across multiple frameworks.
Carbon is a strong example of design and implementation being treated as one system rather than separate libraries maintained by different functions.
What to learn: connect foundations and components to production code, versioning and contribution practices.
4. Salesforce Lightning Design System
Salesforce Lightning Design System provides foundations, design tokens, icons, components and patterns for applications in the Salesforce ecosystem.
Its strength is domain specificity. Enterprise CRM products have dense data, forms, permissions and workflows that need patterns different from a simple consumer app.
What to learn: design systems become more valuable when they encode recurring domain problems, not only generic UI controls.
5. Shopify Polaris
Polaris documents patterns and components for building commerce experiences in Shopify’s ecosystem.
It is useful to study because product language, merchant tasks and commerce-specific decisions are part of the system rather than being left to every feature team to rediscover.
What to learn: include product-content and workflow guidance where repeated domain decisions matter.
6. Atlassian Design System
Atlassian Design System includes foundations such as tokens, spacing and typography, reusable components, content guidance and Figma/developer tools.
Atlassian also treats documentation, support and maintenance as part of the system. That matters at scale because a component nobody understands or trusts is not truly reusable.
What to learn: adoption requires documentation, contribution rules and a service model, not just a library.
7. GitHub Primer
Primer is GitHub’s design system. It includes product UI, primitives, accessibility guidance, icons and brand resources.
Primer is especially useful for teams building technical tools because it demonstrates how a system can support dense, information-rich developer interfaces without losing consistency.
What to learn: tokens and primitives provide a stable foundation for many specialized product surfaces.
8. Microsoft Fluent
Fluent is Microsoft’s design system for productivity experiences across its ecosystem.
Its scale makes it a useful reference for themes, accessibility, cross-platform consistency and interaction patterns that have to work across many products and devices.
What to learn: a large design system needs flexible foundations without allowing every product to become visually unrelated.
What every strong design system includes
Foundations
Color, typography, spacing, grids, elevation, motion and other primitives should be expressed as reusable decisions, usually through tokens.
Components
Components need states, variants, behavior and usage guidance. A button component without rules for loading, disabled, destructive or permission states still leaves important decisions to feature teams.
Patterns
Patterns combine components to solve repeated product problems such as forms, navigation, search, bulk actions, onboarding and empty states.
Content guidance
Voice, terminology, labels, errors and microcopy are part of the user experience and should not be treated as an afterthought.
Accessibility guidance
The system should document accessible interaction and implementation expectations. This helps teams make better decisions, but product teams still need to validate the final experience.
Design-to-code connection
Figma components and production components should have a clear relationship. The further they drift, the more “using the design system” becomes visual imitation rather than actual reuse.
Governance
Teams need to know who owns the system, how a component is proposed, how changes are reviewed and how deprecated patterns are removed.
How AI changes design-system work
AI makes it faster to generate interface options, which increases the importance of design-system context. Without constraints, generation can multiply inconsistent components just as quickly as it creates useful screens.
For existing products, evaluate whether an AI design tool can work with the real components, variants and tokens rather than merely approximate the visual style. See our guides to AI design software and Figma AI tools.
How to use these examples when building your own system
- Start with repeated product decisions. Do not build a component library because other companies have one.
- Define foundations and tokens. Create the shared language first.
- Build the highest-use components. Buttons, fields, navigation and common data patterns usually come before exotic components.
- Document states and rules. Include when not to use a component.
- Connect design and code. Align names, variants and ownership where possible.
- Add contribution governance. Make it clear how the system evolves.
- Measure adoption. Look at reuse, exceptions and areas where teams keep creating local alternatives.

FAQ
What is a design system?
A design system is a shared set of foundations, components, patterns, guidance and implementation resources used to create consistent product experiences.
What is the difference between a design system and a component library?
A component library is one part of a design system. A design system also includes foundations, interaction rules, content standards, patterns, accessibility guidance and governance.
Which design system is the best example?
Material, Carbon, Atlassian Design System and Primer are especially useful because their public documentation shows both the visible components and the thinking around foundations, implementation and contribution.
