The UI design system for agentic workflows
Bronze UI helps you craft clear, consistent, and accessible user interfaces when writing AI-generated code.
Overview
Bronze UI is a component library for building consistent user interfaces in the age of generative AI. Define your design rules through a centralized configuration, and let the system enforce those rules automatically.
With a concise, semantic API and example-driven documentation, Bronze UI reduces ambiguity for both developers and AI agents. The result is a system where interfaces are crafted to be predictable and aligned with design intent by default.
Motivation
Building a robust user interface requires careful consideration across visual design, accessibility, performance, and more. Design systems can encode many of these decisions, but they have to be applied consistently in order to be effective.
With agentic workflows, maintaining consistency becomes more difficult. AI can generate interfaces quickly, but without clear constraints, it can also introduce fragmentation, misuse components, or invent patterns that don’t hold up in practice.
Bronze UI provides an opinionated structure for building interfaces that prioritizes clarity and determinism, while still leveraging the efficiency of AI-assisted workflows. By reducing ambiguity in both API design and documentation, it enables more reliable outcomes, whether interfaces are written by humans or generated by AI.
Key Features
Machine-readable
Documentation is designed to be accessible to humans and AI agents. Clear Markdown structure and pattern-based examples make it easier for LLMs to interpret and reproduce intended usage with minimal ambiguity.
Consistent
A centralized system of tokens, patterns, and conventions ensures all components align by default. Predictable APIs and TypeScript types reduce variation and help prevent fragmented or inconsistent UI generation.
Semantic
Components are built around intent, not just visual appearance. By separating semantics from styling, the system makes it easier for both developers and AI to choose the right abstraction for each use case.
Deterministic
There is a clear, preferred way to use each component. By limiting ambiguity and avoiding overlapping patterns, Bronze UI reduces guesswork and improves reliability in generated code.
Performant
Bronze UI is built to support modern applications, with support for server-side rendering and tree-shaking. The system remains lightweight and efficient without sacrificing structure.
Accessible
Accessibility is built in from the start. Components follow WAI-ARIA standards and support keyboard navigation and screen readers by default.
