  • Generate UI components from uploaded images.
  • Modify existing UI components using natural language or images via a conversational interface.
  • Convert generated UI (HTML) into React framework code.
  • Convert generated UI (HTML) into Svelte framework code.
  • Convert generated UI (HTML) into Web Components code.
  • Utilizes OpenUI Lang v0.5, a compact, streaming-first language for UI generation.
  • Generates responsive designs adaptable for various device sizes.

use cases

Who Should Use openui?

OpenUI targets a range of professionals involved in web development and design, offering tools to streamline prototyping, accelerate development, and adapt existing designs. Its capabilities are particularly beneficial for those working with Large Language Models (LLMs) for application development.

  • Developers: For rapidly prototyping and building UI components, significantly reducing development time and effort.
  • Web Developers: To generate UI code in various formats including HTML, JSX, React, Svelte, and Web Components, facilitating integration into diverse tech stacks.
  • Designers: For quick visualization and iteration of design ideas, fostering a more dynamic and imaginative development process.
  • Organizations: To adapt and modify existing UI designs by uploading an image and making changes via a conversational interface, useful for updating legacy systems.
  • Researchers and Innovators: For prototyping and testing next-generation tooling built on top of Large Language Models (LLMs).

pricing

openui Pricing & Plans

OpenUI, as an open-source generative UI framework, is free to use when self-hosted. The project's GitHub repository (thesysdev/openui) allows for direct deployment without licensing costs. It is important to distinguish OpenUI from 'OpenWebUI,' which is a separate, albeit related, self-hosted AI chat interface. Managed hosting services for OpenWebUI, such as those offered by Elestio, provide various plans based on resource allocation. These plans are not applicable to the OpenUI generative UI framework itself.

  • OpenUI (Generative UI Framework): Free (self-hosted, open-source)
  • OpenWebUI (Managed Hosting by Elestio - distinct tool):
  • NC-MEDIUM-2C-4G: $18/month (2 CPUs, 4 GB RAM, 60 GB SSD)
  • NC-LARGE-4C-8G: $33/month (4 CPUs, 8 GB RAM, 100 GB SSD)
  • NC-XLARGE-8C-16G: $66/month (8 CPUs, 16 GB RAM, 200 GB SSD)
  • NC-2XLARGE-16C-32G: $136/month (16 CPUs, 32 GB RAM, 400 GB SSD)
  • NC-3XLARGE-16C-64G: $204/month (16 CPUs, 64 GB RAM, 600 GB SSD)
  • Additional Disk Storage: $0.15/GB/month (for OpenWebUI managed hosting)

Uizard allows users to generate entire projects, screens, and themes from text prompts, screenshots, or even hand-drawn wireframes, making it highly versatile for initial design ideation.

Like OpenUI, Uizard focuses on generating UI from natural language, but it extends its input capabilities to include scanning screenshots and wireframes, and offers a broader scope by generating entire projects and themes.

2
Motiff AI

Motiff AI focuses on generating production-ready UI from various inputs, including text, images, and PDFs, with strong emphasis on maintaining brand consistency and exporting clean code.

Motiff AI is similar to OpenUI in generating UI from text, but it differentiates by accepting more input modalities like images and PDFs, and by providing advanced features for brand consistency and direct export of production-ready React/HTML code.

3
Banani

Banani generates interactive, multi-screen UI prototypes from plain language descriptions or design references, allowing for refinement and export to Figma or code.

Banani directly competes with OpenUI by generating UI from text prompts, but it emphasizes creating interactive, multi-screen prototypes and offers export options to Figma and code, catering to a broader design and development workflow.
