HeroUI Chat is an AI-powered text-to-app builder that generates production-ready React code from natural language prompts or screenshots. Built on the HeroUI component library (formerly NextUI) with 23,000+ GitHub stars and 600,000+ monthly downloads, the platform turns design ideas into functional frontends in seconds. Founded by Junior Garcia, backed by Y Combinator, and powered by Together AI's Code Sandbox infrastructure, HeroUI Chat represents the convergence of a battle-tested component library with AI code generation — a combination that produces cleaner, more consistent output than generic AI builders.
The workflow is designed for speed. You describe the UI you want — a dashboard with a sidebar, a pricing page with tiers, a login form with social auth — and HeroUI Chat generates complete React code using HeroUI components and Tailwind CSS. Alternatively, you can upload a screenshot of any UI and the system recreates it as functional code. Live previews show the result immediately, and you can iterate through conversational refinements — adjusting colors, layouts, spacing, and components — without leaving the chat interface. Dev Mode lets you manually edit generated code without consuming AI credits.
The component foundation is what separates HeroUI Chat from generic AI code generators. The 44+ available components in the HeroUI library are accessible, well-designed, and follow WAI-ARIA guidelines with WCAG compliance including keyboard navigation and screen reader support. Because the AI generates code using this specific library rather than arbitrary HTML/CSS, the output is consistent, maintainable, and follows established design patterns. Design and code stay in sync through tokens, variables, and component structure that map cleanly from Figma to React.
The technical stack is modern and production-oriented. Together Code Sandbox provides managed infrastructure for executing AI-generated code, reducing preview launch times from 2 minutes to 2 seconds compared to HeroUI's earlier WebContainer approach. The integrated git system within the sandbox provides version control, allowing users to manage changes and roll back to previous versions. Code can be downloaded as a ZIP or installed via the HeroUI CLI, and one-click deployment is available for immediate hosting.
HeroUI Pro extends the ecosystem with premium components, templates, and AI tooling for React and React Native. Advanced Skills and MCPs give AI tools like Cursor, VS Code, and Claude deeper design context, so they generate code that uses Pro components and follows your design system out of the box. The Figma Kit ensures visual and functional coherence. Pricing for Pro starts with individual and team plans, with pre-sale pricing available before the estimated April 2026 launch.
The platform targets several key use cases. Rapid prototyping for startup founders who need polished UIs without a full frontend team. Feature scaffolding during development sprints where developers need common components fast. Design-to-code handoff where designers upload screenshots and developers receive ready-to-use React code. And learning, where new React developers can see how professional components are structured by observing the generated output.
