Nice service.

A small comment. Let the url input be case insensitive (the https + domain part of course). Using it from mobile often set first H in https as uppercase and this mails your site fail.

A potential alternative is to set the following HTML attributes on the <input> field:

    autocorrect="off"
    autocapitalize="off"

URL inputs are otherwise also supported via <input type="url">
