Custom Domain (CNAME + SSL)

Now a custom domain can be added to the Gumlet source. This allows serving images from your own domain (images.example.com) rather than a Gumlet subdomain (example.gumlet.io).

Custom Domain with Gumlet CDN#

This guide assumes that you have already 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 a source is created, please follow these steps to add a custom domain:

1. Go to edit source.#

2. Create a custom domain#

Go to the "Custom Domain" section on the edit source page.

  1. Enter your desired domain in the "Custom Domains" section.
  2. Click Add custom domain

3. Create a CNAME record in your DNS records#

Create the following CNAME record to start using your custom domain. Please replace images.example.com with your own domain. If your gumlet source is example.gumlet.io then add the following CNAME record.

images.example.com CNAME example.gumlet.io

4. Verify the CNAME record#

Once you add CNAME record, click on verify button. If eveyrthing is correct, your custom domain will be sucessfully created.

tip

That's it! Your custom domain will be live with a valid SSL certificate in few minutes. Open your custom domain in a new tab to validate the setup.

5. Update your Gumlet integration#

Update your Gumlet (JavaScript or WordPress) plugins to change how the images are served. Please use the new custom domain (images.example.com) in your Gumlet integration instead of the old Gumlet subdomain (example.gumlet.io).

caution

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

FAQs and Troubleshooting#

Does my plan include a Custom domain?#

All paid plans (Pro, Appsumo, Business & Enterprise) support custom domain. Each custom domain costs $5 / month extra. Check your plan details on the billing panel to see if you have any free custom domains.
