Custom domain & DNS
Connecting a domain via Cloudflare DNS and verifying TLS.
- How do I connect a custom domain?Open /domain. Enter your domain and the guide tailors the steps for Cloudflare or your DNS provider. TLS is issued automatically once verified.
- Does Blanca's Builder require Cloudflare?No, but Cloudflare is recommended because the platform itself is hosted on Cloudflare and DNS detection is automated for it.
- Which DNS providers are supported?Any DNS provider works. The guide includes step-by-step screenshots for Cloudflare, AWS Route 53, Google Domains and the common European registrars.
- Which DNS records do I need to add?Usually a single CNAME for the apex or a subdomain. The guide tells you the exact target record for your project.
- Can I use an apex domain (no subdomain)?Yes. With ALIAS or ANAME at your DNS provider, or via Cloudflare's flattening. The guide detects which option your registrar supports.
- How long does DNS propagation take?Usually under 15 minutes with Cloudflare and up to 24 hours elsewhere. The guide polls DNS and notifies you the moment verification succeeds.
- Do I need to upload a TLS certificate?No. Blanca's Builder issues TLS automatically through Let's Encrypt. Certificates renew before expiry without action from you.
- Can a project use multiple domains?Yes. Add each domain in Domain, Aliases. One domain is the canonical and the others 301-redirect to it.
- How do I change the canonical domain?Domain, Settings, Set canonical. SEO metadata, sitemap and JSON-LD all switch immediately to the new canonical.
- How do I disconnect a domain?Domain, the domain, Disconnect. We stop serving the project on that hostname. DNS records at your provider stay until you remove them.
- Is there a staging or preview domain?Yes. Every project has an internal preview URL on the blancasbuilder.com subdomain. Use it to share work in progress.
- Does a custom domain cost extra?No. Custom domains are included on all paid plans. The Starter plan includes a project on the preview subdomain only.
- Can I use different domains per language?Yes, on Builder and higher. Each language can be served from its own ccTLD or subdomain with automatic hreflang.
- Should I use www or non-www?Either works; pick one and configure the other to redirect. The guide does this automatically when you set the canonical.
- Does connecting a domain affect my email (MX) records?No. Only the records needed for the site are changed. Your MX, SPF, DKIM and DMARC records are not touched.
- Does Blanca's Builder support DNSSEC?DNSSEC is configured at your DNS provider, not at our edge. Enabling it does not break the connection as long as the chain of trust is intact.
- Is CDN and caching included with a custom domain?Yes. Static assets are cached on Cloudflare's edge worldwide. Cache rules can be tuned per project in Domain, Caching.
- Is HTTPS forced for custom domains?Yes. HTTP requests redirect to HTTPS automatically and HSTS is enabled by default.
- My custom domain stopped resolving. What do I check?Open /domain to run a live DNS check. The common causes are an expired registrar invoice or a recent DNS change that did not propagate.
- Can I host the project on a subpath like example.com/app?Yes, with a reverse proxy at your own edge. The guide includes a template for Cloudflare Workers and for Nginx.
