Custom Domain (CNAME+SSL)

You can now add a custom domain to your Gumlet source. It allows you to serve images from your own domain (cdn.example.com) rather than Gumlet subdomain (example.gumlet.io).

Custom Domain with Gumlet CDN

This guide assumes that you have created a Gumlet source. If you are setting up the Gumlet for the first time, please follow this guide to create a Gumlet source.

Once you have created a source, you can easily add custom domain from to your source if your plan support it. Please follow below steps to create custom domain.

1. Go to edit source.

2. Add domain to "Custom Domains & SSL" section

Once you are on source edit page, scroll down to this section.

  • You need to select "Gumlet CDN" in CDN Type field.

  • You need to enter your desired domain in "Custom Domains" section.

Require custom domain with CloudFront CDN?

Custom domain with CloudFront CDN are only supported for Business plan users. Please contact our support for the same.

3. Create CNAME record in your DNS records

Once you save the source settings, you need to create following CNAME record to start using custom domain. Please replace cdn.example.com with your own domain.

cdn.example.com CNAME edge.gumlet.net

That's it! Your custom domain will now be live with valid SSL certificate.

4. Update your Gumlet integration

Now, you have to update your Gumlet (JavaScript or Wordpress) plugins to change how your images are being served. Please use the new custom domain (cdn.example.com) in your Gumlet integration instead of the old Gumlet subdomain (example.gumlet.net).

The site may appear slow, when you switch to new CNAME. It would take a few minutes time to build up the cache. Images will be super fast after a few loads.
