About
Hashbrown is an open-source framework for building browser-native agents and Generative UI in React and Angular. Its strongest fit for this collection is the component-control model: developers expose trusted UI components, while the LLM composes dynamic views, streams them into the page, calls client-side tools, and works with structured data instead of only text.
Summary
1. Framework-level GenUI: Presents Generative UI as a production TypeScript stack, not just a demo
2. Trusted component model: Lets LLMs compose views from React or Angular components the app already owns
3. Client-side tool calling: Connects generated UI to browser state and app services, which is useful for agent-native UX
4. Structured data layer: Uses typed schemas for outputs, component props, and tool definitions
5. Collection fit: A strong reference for teams comparing React/Angular GenUI frameworks beyond Vercel, OpenUI, and Tambo
