Custom domain vs. subdomain

A subdomain is part of an existing domain. For example, foodmart.fillout.com uses “fillout.com” as the main domain, while “foodmart” is the subdomain. A custom domain uses a domain you own, like foodmart.com. This lets you share forms under your own brand instead of “fillout.com”, creating a more consistent experience for respondents.

Custom form links

Customize your form’s share link, subdomain and URL ending.

Custom favicon

Add your logo or icon to a browser tab and in link previews.

Remove Fillout branding

Remove Fillout buttons on form pages.
