Open in v0
Open Shadcn Space components and blocks directly in v0 to customize, iterate, and generate production-ready UI using AI. Start from real, working layouts instead of a blank canvas and move faster from idea to implementation.
Setup
Before you start using Open in v0, make sure you have the following prerequisites in place. This ensures a smooth handoff from Shadcn Space to v0 for customization and code generation.
- Vercel Account
v0 is a Vercel product, so you’ll need an active Vercel account to open, edit, and generate UI. You can sign up for free if you don’t already have one.
- Access to v0
Ensure you have access to v0 by visiting v0.dev and confirming you can create or edit projects.
- Basic Understanding of shadcn/ui
Familiarity with shadcn/ui structure, styling, and component patterns will help you customize and integrate generated code more effectively.
What is Open in v0?
Open in v0 lets you instantly open Shadcn Space components and blocks inside v0 — an AI-powered interface by Vercel for generating and customizing React UI.
Instead of starting from a blank prompt, you begin with a real, production-ready layout from Shadcn Space. v0 understands the structure, styles, and intent of the component, allowing you to refine, extend, and adapt it using natural language.
- AI-assisted customization
Modify layouts, spacing, colors, variants, and behavior using simple prompts instead of manual rewrites.
- Production-ready code output
Get clean, readable React and Tailwind CSS code that follows shadcn/ui conventions and is ready to paste into your project.
- Faster iteration cycle
Iterate on designs in seconds — preview changes instantly and refine until the UI matches your exact requirements.
- Seamless handoff to your codebase
Once you’re satisfied, copy the generated code and integrate it directly into your application without vendor lock-in.
Why use Open in v0?
Open in v0 is designed for developers who want to move fast without sacrificing quality or control. It combines the reliability of Shadcn Space components with the speed of AI-assisted iteration.
- Start from real, working UI
Instead of prompting from scratch, you begin with a tested component or block. This reduces guesswork and ensures a solid foundation from the first iteration.
- Faster design-to-code workflow
Make layout and styling changes using natural language and instantly generate updated code—ideal for rapid prototyping and tight deadlines.
- No lock-in, full ownership
The output is plain React and Tailwind CSS. Copy the code, modify it freely, and maintain full control inside your own codebase.
- Great for teams and solo developers
Designers, frontend developers, and founders can iterate together, reducing back-and-forth and aligning faster on the final UI.
Common use cases
- Rapid prototyping of landing pages and dashboards
- Customizing Shadcn Space blocks to match brand guidelines
- Exploring multiple layout or style variations quickly
- Accelerating MVP and internal tool development
How to use Open in v0?
Open in v0 follows a simple, step-by-step flow that works for both blocks and components. Choose a UI, open it in v0, customize with AI, and copy the final code into your project.
Using with Blocks
Step 1 : Browse the Blocks section and select a block that fits your use case, such as a landing section, dashboard layout, or authentication flow.
Step 2 : Locate the Open in v0 button on the block preview.
Step 3 : Click the button to automatically open the block in v0 in a new tab. The block will be preloaded and ready for editing.
Step 4 : Use natural language prompts in v0 to customize layout, spacing, styles, or content. Once satisfied, copy the generated code into your project.
Using with Components
Step 1 : Navigate to the component you want to customize and review its variants and examples.
Step 2 : Click the Open in v0 button available on the component page.
Step 3 : You’ll be redirected to v0 with the selected component already loaded and structured for AI-assisted editing.
Step 4 : Refine the component using prompts—add variants, update interactions, or align it with your design system—then copy the final code into your codebase.
Limitations
Open in v0 works best with standard shadcn/ui and Tailwind CSS patterns. While it’s great for building and customizing UI, there are a few things it doesn’t support yet.
- Custom Tailwind utility classes (for example, custom animation classes) may not work inside v0.
- CSS variables that are not part of the shadcn/ui theme are not supported.
- Tailwind features like
@applyfor custom styles won’t work in v0. - Animations created using custom CSS keyframes will not run inside v0.
These limitations only apply while working inside v0. Once you copy the code into your project, you’re free to extend, customize, and enhance it however you like.
Best Practices
Before Opening in v0
- Set Your Goals First : Know what you want to customize before starting the AI session to save time and avoid trial-and-error.
- Check Dependencies : Ensure the component or block doesn’t rely on external libraries or features that could break your workflow.
- Prepare Clear Prompts : Write specific instructions for changes you want in layout, styling, or content to get accurate results.
While Working in v0
- Start Small : Make incremental changes rather than large overhauls to avoid unexpected layout issues.
- Use Descriptive Prompts : Include both visual and functional requirements in your instructions for precise results.
- Test Responsiveness & Accessibility :Preview your edits on different screen sizes and check accessibility to ensure quality.
- Save Versions : Keep multiple iterations so you can compare approaches and revert if needed.
Exporting Back to Your Project
- Review & Optimize : Check the generated code for best practices and make adjustments to fit your project.
- Check Dependencies : Make sure all required imports are included before integrating the code.
- Test in Context : Run the component in your project to verify functionality, responsiveness, and consistency.
