  4. Now, go to your domain name registrar's website and create a CNAME entry using the copied URL. If you've misplaced the url you were provided, not to worry! You can use instead - it's completely interchangeable with any domain.

Here are some things to remember when using the custom domain tool in the Project Editor:


  • After you have successfully added your custom domain and generated the url, this information will not show again in the custom domain tool.  So, you may want to save this information in your notes locally.
  • If you see the message "this custom domain is already registered", it means that the custom domain is already connected to a different Glitch project.  If you need help figuring out what project that is, you can contact Glitch Support.  We are happy to look it up for you!
  • The information in this help article should be used in combination with the dns config instructions provided by your custom domain provider.
