Right now we don't have a native embed feature. However, you can create your own iframe to embed it on your website.
<iframe src="https://vyper.io/c/[CONTEST_NUMBER]?embed=1" style="width: 1000px; height: 3280px; border: 1px solid #DDD" scrolling="no" frameborder="0"></iframe>
Replace [CONTEST_NUMBER] with the number of your contest. You can also style the inline CSS however you want to make the contest look good on your website.
