Tutorial: How to set up a custom subdomain for Namecheap

Connect a Namecheap subdomain to your Softr app.

First, log in to your Namecheap account dashboard.

Next to the domain you want to point to Softr, click on “Manage”.

Click into the “Advanced DNS” tab. If you see CNAME Record and URL Redirect Record with parkingpage.namecheap like values please delete them.

If your screen doesn’t look like the image above, it’s most likely because you have your DNS pointed elsewhere. In other words, to create DNS records at Namecheap, you need to be using “Namecheap BasicDNS” which is included with every domain. You can check by going into the “Domain” tab.

Click into the “Advanced DNS” tab and then click on “Add New Record”. If you see an A Record that already exists you will simply need to edit it (skip to the next step).

Notion image

A subdomain needs a single A record — no CNAME. Set its Host to the subdomain label on its own, and its Value to the IP address Softr shows you under Settings → General → Domains.

TypeHostValue
A Recordthe subdomain label only — portal for portal.example.comthe IP address Softr shows you

Softr lists a single A record for a subdomain, and its Host is the subdomain label on its own.

Then create that same record in Namecheap:

The finished record in Namecheap’s Advanced DNS tab.

DNS changes can take a few hours to take effect.

You are done!
