How to connect your repl to a custom domain
Connecting your domain to your repl
First, you need to go into the webview of your repl and click the pencil icon to the right of the address bar:
From there, you can add your domain to the domain linking panel:
Next, you will be prompted to copy information for the CNAME and TXT records. The CNAME record points your domain to your repl, and the TXT record verifies that you own the domain.
Once you have copied the info, you can add the CNAME and TXT records to your domain. You can link your repl to a root domain or a subdomain. In my case, the root domain would be
thedevbird.com, but for this tutorial, we will link the domain:
tutorial.thedevbird.com to our repl.
Note: I am using Cloudflare for DNS management in this tutorial, but it should be comparable to any other DNS manager
The name is your subdomain prefix, such as
tutorial.thedevbird.com) or your root domain:
Some DNS services do not allow you to use your root domain with a CNAME record. In that case, you will need to use an A record. Replit's domain linking panel should show an
A record automatically whenever you enter only your root domain:
The target is what the record will point to, usually the information you copied from the domain linking panel.
The waiting game
Unfortunately, the time to fully propagate DNS changes can range from a few minutes to about 24-48 hours. We recommend using a tool such as https://whatsmydns.net/ to keep track of the DNS propagation. All you need to do is input your custom domain (
tutorial.thedevbird.com in this case) and select the DNS record type you want to check.
In the screenshots below, you can see how quickly the TXT record propagated. In contrast, when making this tutorial, the CNAME record had only propagated to one primary DNS server in the same time span.
The key to linking your domain is patience. Your repl won't be able to connect to your custom domain until the DNS records are propagated all the way through.
We have liftoff!
Once your DNS records have been fully propagated, you can check back on the domain linking panel of your repl, which should show that your domain has been verified:
