openui: an open-source AI-powered UI generator that renders live descriptions into framework-ready code

What it solves

Building user interface (UI) components manually is often a slow and tedious process. OpenUI simplifies this by allowing users to describe the interface they want in plain language and see it rendered instantly, speeding up the prototyping and design phase of application development.

How it works

OpenUI uses Large Language Models (LLMs) to translate natural language descriptions into UI code. It integrates with various model providers via LiteLLM, supporting OpenAI, Groq, Gemini, Anthropic, and local models via Ollama. Users can describe a UI, request iterative changes, and convert the generated HTML into different frameworks like React, Svelte, or Web Components.

Who it’s for

Developers and designers who want to quickly prototype UI components using AI, as well as teams looking for an open-source alternative to tools like v0.

Highlights

• Live Rendering: See UI components rendered in real-time based on text descriptions.
• Multi-Framework Support: Convert generated HTML to React, Svelte, and Web Components.
• Broad Model Compatibility: Works with a variety of LLMs including proprietary APIs and local models via Ollama.
• Iterative Design: Ability to ask for specific changes to the rendered UI to refine the design.
