AI Speeds Up UI Generation but Raises New Design System Consistency Challenges

AI coding tools can now generate UI components, tests, documentation, and variations within minutes, significantly accelerating frontend development. However, this speed introduces new risks: duplicate components, inconsistent APIs, mismatched design tokens, and documentation that quickly falls out of sync with actual code. Unlike traditional bottlenecks around creation speed, teams now face the harder problem of keeping an entire UI system coherent as both humans and AI agents modify it rapidly. A product called Vellira is being built specifically to address these consistency challenges across React and React Native codebases. The core argument is that as AI generation improves, projects need stronger, more explicit contracts to ensure every change still belongs to the same cohesive product and engineering system.
