customdomain

A practical workflow

1. User taps 'Connect your domain' in the product, the system detects the DNS provider and configures DNS automatically, then issues HTTPS and serves the domain live.
2. The embedded widget allows a customer to connect their domain with one click, automatically detecting provider, configuring DNS, and securing HTTPS in seconds.
3. Developers can start a connection via REST API by posting the domain, which triggers detection, authorization, DNS writing, and verification.

   features

   Before: ["Automatic DNS record configuration including A, CNAME, TXT, MX, SPF, and DKIM records for apex, www, and subdomains.","Automatic SSL certificate issuance and renewal before expiry to ensure domains are never served with half-issued certificates or browser warnings.","Provider auto-detection that fingerprints the DNS host from public records and selects the appropriate connection method such as OAuth, scoped token, or guided steps.","Edge serving option to serve customer domains from Custom Domain's edge or verify and hand DNS back to the user's own stack, allowing flexible request path control.","DNS drift monitoring that re-checks DNS records every hour and re-issues certificates on change, alerting users before their customers notice issues."]

   After: ["Provider auto-detection that fingerprints DNS hosts and selects the appropriate connection method such as OAuth or scoped tokens.","Automatic DNS record creation including A, CNAME, TXT, MX, SPF, and DKIM records for apex, www, and subdomains.","Automatic SSL certificate issuance and renewal before expiry to ensure domains are never served with partial certificates or browser warnings.","Optional edge serving to serve customer domains from Custom Domain's edge or to verify and hand DNS back to the user's own stack.","Drift monitoring that re-checks DNS records every hour and re-issues certificates on change, alerting users before customers notice."]

   limitations

   Before: []

   After: ["The API outage pauses new connections and first-time certificate issuance but does not affect domains already live and serving.","DNS forbids a CNAME at the apex domain, so flattening (ALIAS/ANAME) or A records are used instead, which may require special handling."]

   walkthrough

   Before: ["Users initiate a domain connection via API or embedded widget, the system detects the DNS provider and configures DNS records automatically, then issues SSL certificates and serves the domain over HTTPS.","The customer taps Publish in the platform, the system writes A and CNAME records to the edge, and the site goes live on the customer's domain with HTTPS secured.","The platform continuously monitors DNS records hourly and re-issues certificates if changes are detected to maintain domain health."]
