Replit Unveils Its Most Comprehensive Design Support Feature for Building AI Apps

Replit announced its most comprehensive Design Support feature yet, aiming to set a new standard for building AI apps. Users can now consistently build apps that perfectly follow their company's brand and design guidelines, without the hassle of manually editing every single component.

The new Themes feature lets you manage colors, fonts, and UI properties across an entire app with a single update.

• Create and apply themes to Agent applications
• Instantly reflect changes across all components with one update
• Save themes for reuse in future app builds

Notably, TweakCN, an open source project optimized for customizing Shadcn themes, has been integrated directly into the theme editor. In addition, powerful integrations are available for enterprise customers:

• Figma design system import: Import a Figma design system and apply it to apps built by Agent
• Package/library import: Connect packages containing design tokens and rules and apply them across all apps

With this update, users can go beyond simple prototyping and confidently build customer-facing and commercial apps that fully reflect their brand identity.
