How it works
Step by step
01
Publish on Castee
Get your site live on a cst.fm subdomain first — instant and free.
02
Add your domain
Enter your domain in site settings. Castee shows the exact DNS records to add.
03
Verify & go live
Once DNS propagates, your site serves on your custom domain with automatic SSL.
Can I use a subdomain like podcast.mybrand.com?
Yes. Add a CNAME record pointing your subdomain to Castee — works great for show-specific URLs.
Do you support apex/root domains?
Yes. Apex setup uses ALIAS/ANAME or A records depending on your DNS provider — instructions included.
