Set a custom domain

Setting up a custom domain ensures that your site is properly configured for branding and search engine optimization. By following the steps outlined, you can effectively connect your desired domain, enhance your online presence with a logo, and optimize your site’s metadata for better visibility.

Connect your Domain

1On the left-hand sidebar, click Agency.

2Click Custom Domain.

3Enter the custom domain or subdomain you want to use and click Connect Domain.

4Synthflow will generate a DNS record for you to add to your domain provider’s dashboard. Allow up to 24 hours for the record to propagate. To check if the update is complete, click Check DNS records.

DNS Server Requirements

To ensure SSL certificates can be automatically generated and renewed, your domain’s DNS server must support CAA (Certification Authority Authorization) record queries. If your DNS provider or internal DNS system does not support CAA queries, automated certificate generation (via Synthflow’s infrastructure) will fail.

💡 Tip: Most modern DNS providers (e.g., Cloudflare, Google Domains, AWS Route 53) already support CAA records. If you’re using an on-premise or legacy DNS server, verify this capability before connecting your domain.

Update Site Metadata

Once the DNS changes take effect, you can set key information that improves your site’s visibility and appearance in search results.

1Enter the site name that will appear in search engine results.

2Upload a logo to display alongside your site.

3Enter an SEO description to appear in search engine results.

4Click Update metadata.

Removing or Disconnecting a Domain

Selecting this option will disassociate your domain from Synthflow and remove all related configurations, including routes, files, and metatags.
