Choosing between v0 and Same.new (formerly Same.dev) comes down to whether you want to build a frontend layout from scratch or clone an existing design. While both leverage natural language prompts to output React and Tailwind CSS, they serve different starting points in the design process.

Meet the Contenders

Let’s look at the primary interface and core architectures of both systems.

What is v0?

v0 is Vercel’s conversational AI frontend generator. You describe your interface or upload an image, and the AI scaffolds clean React components styled with Tailwind CSS and shadcn/ui. The editor highlights visual preview tabs, allowing developer-friendly component iterations.

What is Same.new?

Same.new (formerly Same.dev) is a visual cloning and frontend prototyping tool. Instead of building from text prompts, you paste a live URL, and the AI agent attempts to replicate the site’s layout, fonts, and colors into a modifiable React workspace. From there, you use natural language prompts to customize the design.

The Core Difference

The main difference between the two tools lies in their design origin:

• v0 builds layouts from conversational descriptions or image sketches, focusing on modular, developer-ready React code.
• Same.new builds layouts by crawling and replicating existing live websites from their URLs, focusing on design benchmarking and visual duplication.

v0 behaves like a custom frontend developer, while Same.new behaves like a visual crawler that creates editable copies.

Head-to-Head Comparison

Here is how both platforms compare across developer experience, code quality, backend power, and deployment.

1. Developer Experience & Iteration Speed

v0 provides a highly stable, interactive chat experience. It is optimized for Next.js and shadcn/ui. However, when chat histories grow beyond 5 - 10 messages, the AI quality can degrade, sometimes producing buggy code or ignoring previous rules, which burns through your credits.

Same.new lets you skip manual layout scaffolding by cloning existing pages. However, the cloning engine struggles with complex layouts, nested grids, or highly interactive elements, which can require manual developer cleanup. Additionally, users have reported issues with destructive AI updates, where a simple request to change a layout section accidentally deleted hundreds of lines of code.

2. Code Quality & Portability

Both platforms generate standard React and Tailwind CSS code without proprietary visual components, meaning there is zero vendor lock-in.

v0 is generally better at generating clean, modular React file structures that conform to modern frontend frameworks. It splits layouts into readable components.

Same.new compiles a standard Vite project. While the initial visual output is fast, the underlying code can sometimes be bloated and require cleanup, as the cloning agent prioritizes visual alignment over code efficiency.

3. Database & Backend Capabilities

Neither v0 nor Same.new has database capabilities:

• v0 is strictly frontend. You must manually wire the exported React components to external backends like Supabase or Firebase.
• Same.new does not connect to external databases, and has no native authentication or server-side workflows. It is purely a visual design scratchpad.

4. Hosting & Deployment Options

v0 integrates directly with Vercel’s global CDN, providing fast, one-click preview deployments for staging.

Same.new relies on exporting code. While you can preview your cloned layouts inside the editor, deploying a production app requires downloading the React repository and hosting it on your own server or static web platform.

Pricing Comparison

Pricing on both platforms is based on usage-based credits:

• v0 uses a token-based calculation. The Team plan is $30/user/month and includes $30 of credits. Model usage rates vary from $1/million input tokens on v0 Mini to $30/million input tokens on v0 Max Fast.
• Same.new has a Free tier and a Pro plan starting at $10/month, which includes 2 million tokens. Additional tokens are charged at $10 per 2 million tokens. This makes Same.new a highly affordable playground, though the token consumption scales with layout complexity.

Use Case Fit: When to use which?

When to choose v0

• You want to design responsive Next.js components using shadcn/ui from scratch.
• You already have a backend and need clean styled frontend files to integrate.
• You need a stable conversational assistant for frontend code generation.

When to choose Same.new

• You want to clone the visual design and layout of an existing website to use as a starting point.
• You want a low-cost prototyping environment for visual brainstorming.
• You need to quickly replicate the look and feel of a competitor landing page.

When neither v0 nor Same.new is the right fit

Generative frontend tools require developer oversight to become functional apps. If you do not have coding experience, managing these custom code projects can lead to frustration.

For native mobile apps

Neither v0 nor Same.new compiles native iOS and Android packages for App Store distribution. If you need native mobile apps, FlutterFlow is the standard. It builds mobile layouts visually and outputs native Dart code.

For internal tools and client portals

If you are building database-driven tools like customer portals, CRMs, or directories, maintaining custom code is unnecessary. Softr builds secure business applications on top of Airtable, Google Sheets, or Softr Databases. Softr handles permissions, design layouts, and security rules visually, meaning your team can update the app without writing code or paying for AI credits.

For professional developer environments

For experienced developers who want to work locally, prompt-to-preview clouds can feel restrictive. Cursor is an editor fork that runs locally and offers context-aware multi-file editing. Replit remains a solid option if you need a collaborative cloud IDE that runs backend code containers and managed databases.

Verdict

• Choose v0 if you want to generate high-quality React components and clean Next.js interfaces from scratch using shadcn/ui.
• Choose Same.new if your primary goal is visual cloning - extracting the layout and styling of an existing website from its URL to modify it conversationally.
