Custom Domains

info

Custom Domains is the feature of Jitsu Cloud. To implement custom domains for self-hosted Jitsu you need to use 3rd party solutions such as Cloudflare or Caddy.

What are Custom Domains?

If you're implementing client side-tracking with Jitsu, the javascript code on your web page will be sending data to a dedicated subdomain <site-id>.d.jitsu.com. While this works fine, some data may be lost due following reasons:

• Ad Blockers are widely used they may block requests to *.jitsu.com domains. Depending on nature of your business, up to 30% of your data may be lost
• The other reason for data loss is Safari's tracking prevention feature. Safari will detect that the script is loaded from d.jitsu.com domain and will block it from accessing certain data such as analytics cookies. As a result, the precision of your analytics will be affected.

Custom Domains to the Rescue

To solve this problem, Jitsu Cloud allows you to attach custom domains to your Sites. Instead of using <site-id>.d.jitsu.com, the tracking will be loaded from <site-id>.your-site.com, such as events.your-site.com. In that case, both Ad Blockers and Tracking Prevention will not affect your tracking.

tip

Consider moving as much of your tracking to server-side as possible. This will improve the quality of your data even further.

How to Configure Custom Domains

When you create a new Site, add your subdomain name to the Custom Domains field. Then point your subdomain to cname.jitsu.com
