Custom Domains

Using Your Own Domain

Connect a custom domain to replace the default .fastmode.ai subdomain.

Adding a Custom Domain

  1. Go to Settings in your dashboard
  2. Scroll to Custom Domain
  3. Enter your domain (e.g., www.example.com)
  4. Click Add Domain

DNS Configuration

Add a CNAME record at your domain registrar:

TypeNameValue
CNAMEwwwyour-subdomain.fastmode.ai

For apex domains (example.com without www), you may need an A record or ALIAS record depending on your provider.

SSL Certificate

Fast Mode automatically provisions a free SSL certificate for your domain. This may take a few minutes after DNS propagates.

Verification

After adding DNS records:

  1. Wait for DNS propagation (up to 48 hours, usually minutes)
  2. Fast Mode will show "Active" when the domain is connected
  3. Visit your domain to confirm it's working

Troubleshooting

  • Domain not connecting? — Check DNS records are correct
  • SSL errors? — Wait for certificate provisioning
  • Shows wrong site? — Clear browser cache
