Introduction

Gamma allows you to publish sites using a default gamma.site domain or your own custom domain. If you’ve already published a site and want to change its domain, this guide walks you through updating it step-by-step, including DNS setup, site configuration, and publishing.

What is a Custom Domain in Gamma?

A custom domain allows you to host your Gamma site on your own branded URL (e.g. yourcompany.com) instead of Gamma’s default subdomain (e.g. yoursite.gamma.site). This improves brand visibility and SEO.

Note: Custom domains are on available on Gamma’s Pro plan. Visit [Gamma Plans] to upgrade.

How to Change Your Gamma Site’s Domain

Step 1: Review Your Existing Domain Setup

Before making changes, consider:

Whether your existing domain already points to other content.
If you want to avoid replacing your current site, use a subdomain instead (e.g. gamma.yourdomain.com).

Pro Tip: Avoid downtime by configuring a subdomain before making changes to the root domain.

Step 2: Disconnect Current Domain (if applicable)

If your domain is already connected elsewhere (e.g. to Squarespace or Webflow), you'll need to:

Go to that platform.
Unlink the domain.
Free it up for use in Gamma.

Step 3: Access Domain Settings in Gamma

Open your Gamma site.
Click the ... (More) button next to the Publish button.
Select Site Settings.
Navigate to the Domains tab.

Step 4: Enter Your New Domain

Click Add domain.
Enter your custom domain (e.g. www.yourdomain.com).
Choose Automatic Setup (recommended) or Manual Setup.

Note: It may take up to 24 hours for domain verification and SSL certificates to activate.

Step 5: Update DNS (Manual Setup Only)

If you choose Manual Setup, you’ll need to:

Copy the DNS records provided by Gamma.
Go to your domain registrar (e.g. Namecheap, GoDaddy).
Paste the records into your DNS settings.

Step 6: Publish Your Site

Once your domain is connected:

Click Publish to push your site live to the new domain.

FAQs & Common Issues

Can I go back to a gamma.site domain later?

Yes. You can return to your gamma.site subdomain at any time by removing the custom domain under Site Settings.

Why is my site showing a security warning?

After setting up a new domain, SSL certificates may take a few hours to activate. Try again later. If the issue persists after 24 hours, contact Gamma support.
