OpenUI lets you describe UI components in natural language, renders them live, and converts the generated HTML into multiple frontend frameworks. It is positioned as an open-source alternative to v0.
Project overview
It accelerates UI prototyping by combining live rendering with multi-framework code conversion, supporting local models and optional remote APIs.

Best for
Developers who want to accelerate frontend prototyping and obtain multi-framework code from natural language descriptions.
Key capabilities
Users describe a UI using natural language, see it rendered live, and ask for dynamic changes to the generated interface.
Converts generated HTML into React, Svelte, Web Components, and other frontend frameworks.
Limitations and risks
The project is acknowledged as not as polished as proprietary alternatives.
Running in a Codespace or similar environment requires at least 16GB of RAM.
The data boundary is external_optional; inference may use remote external services and APIs unless configured otherwise.
Getting started
Run the provided Docker run command and visit http://localhost:7878. No coding is required to start using the web GUI.
