Frequently Asked Questions
Can V0 clone websites like JustCopy.ai?
No. V0 generates components from prompts or images, but it cannot automatically clone existing websites from a URL. That's JustCopy.ai's core feature.
Do I need to know React to use V0?
Yes. V0 generates React component code that you need to integrate into your project manually. You need to understand React, TypeScript, and how to set up a React project. JustCopy.ai requires zero coding knowledge.
Which tool is faster for launching a complete website?
JustCopy.ai is significantly faster - under 2 minutes from URL to deployed website. V0 requires you to generate components, set up a React project, integrate the components, configure deployment, and host it yourself - typically 30+ minutes minimum.
Does V0 include hosting?
No. V0 only generates component code. You need to deploy and host yourself (typically on Vercel, which costs extra). JustCopy.ai includes hosting in the subscription.
Can I export code from both platforms?
Yes. V0 provides component code you can copy. JustCopy.ai lets you export the complete website codebase (Next.js/React) to host elsewhere or further customize.
Which is better for non-technical users?
JustCopy.ai is designed for non-technical users - no coding required. V0 is built for developers and requires React knowledge. If you can't code, JustCopy.ai is your only realistic option.
Need a Complete Website, Not Just Components?
Clone any website or build from scratch in under 2 minutes. No coding required. Hosting, deployment, and domain support included.
