Connect your custom domain to CupaDev with automatic SSL certificates and global DNS.
Adding a custom domain takes just a few minutes:
Go to your project settings and click "Add Domain". Enter your domain name (e.g., example.com or www.example.com).
Update your domain's DNS records with your domain registrar:
CupaDev automatically verifies DNS configuration and provisions an SSL certificate. Your domain will be live within minutes.
Different record types for different domain configurations:
Use an A record pointing to our IP:
Use a CNAME record:
Add both example.com and www.example.com. CupaDev will automatically redirect one to the other based on your preference.
Configure redirect behavior in Project Settings → Domains → Redirect Options
Every domain on CupaDev gets automatic, free SSL certificates powered by Let's Encrypt.

Certificates renew automatically before expiration
No additional cost for SSL
Covers all subdomains with *.example.com
SSL handled at edge for faster connections
Configure how traffic is redirected between your domains:
Enterprise customers can upload their own SSL certificates:
You can add unlimited domains to a single project:
DNS records haven't propagated yet. This can take up to 48 hours but usually completes within minutes.
Check your DNS configuration with: dig example.com
Ensure DNS is correctly configured and pointing to CupaDev. SSL certificates are issued after DNS verification.
If DNS is correct, wait 5-10 minutes for certificate provisioning.
Make sure the domain is assigned to the correct project and deployment in your CupaDev dashboard.
Go to Project Settings → Domains → Select domain → Remove. The domain will be immediately unlinked from your project.
Use these commands to verify your DNS is configured correctly:
dig example.com AShould return: 76.76.21.21
dig www.example.com CNAMEShould return: cname.cupadev.com
