title: Open in v0
description: Integrate your registry with Open in v0.
---

If your registry is hosted and publicly accessible via a URL, you can open a registry item in v0 by using the `https://v0.dev/chat/api/open?url=[URL]` endpoint.

eg. [https://v0.dev/chat/api/open?url=https://ui.shadcn.com/r/styles/new-york/login-01.json](https://v0.dev/chat/api/open?url=https://ui.shadcn.com/r/styles/new-york/login-01.json)

<Callout className="mt-6">
  **Note:** The `Open in v0` button does not support `cssVars` and `tailwind`
  properties.
</Callout>

## Button

See [Build your Open in v0 button](https://v0.dev/chat/button) for more information on how to build your own `Open in v0` button.

Here's a simple example of how to add a `Open in v0` button to your site.

```jsx
import { Button } from "@/components/ui/button"

export function OpenInV0Button({ url }: { url: string }) {
  return (
    <Button
      aria-label="Open in v0"
      className="h-8 gap-1 rounded-[6px] bg-black px-3 text-xs text-white hover:bg-black hover:text-white dark:bg-white dark:text-black"
      asChild
    >
      <a
        href={`https://v0.dev/chat/api/open?url=${url}`}
        target="_blank"
        rel="noreferrer"
      >
        Open in{" "}
        <svg
          viewBox="0 0 40 20"
          fill="none"
          xmlns="http://www.w3.org/2000/svg"
          className="h-5 w-5 text-current"
        >
          <path

          ></path>
        </svg>
      </a>
    </Button>
