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).

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.
| Type | Host | Value |
|---|---|---|
| A Record | the subdomain label only — portal for portal.example.com | the IP address Softr shows you |

Then create that same record in Namecheap:

DNS changes can take a few hours to take effect.
You are done!
