Linktree doesn't support custom domains. Every Linktree uses its own linktr.biz/yourusername URL, and you can't replace it with your own domain. We also don't provide developer tools for setting up domain forwarding.
Send visitors to your own website
If you'd rather send people straight to your own website, a Redirect might be the right fit. It sends everyone who opens your Linktree directly to a link you choose, for as long as you set.
Redirect is available on Starter, Pro, and Premium plans.
Change your username
You can't change the linktr.biz part of your URL, but you can change your username, the part after the slash. Update it from your Account page.
Tip
