Toddle is designed to provide you with everything you need to build your application. Sometimes, you need to add external scripts to your site. This could be to embed tools like Intercom or Userflow or to include fonts that are not currently supported in toddle.
In the URL panel under the section Head Assets, you can add script, link, and style tags to your page head. Some tools like Amplitude.com prefer that their scripts are added to the page head so that they are loaded before the main content of the page.
One use case for adding assets to the head is to load a custom font that is not yet available in toddle.
