+
+If you've connected a custom domain to Appwrite Sites, you know the process required changing your nameservers to Appwrite. For developers already managing DNS through Cloudflare or similar providers, that meant giving up control over caching, security, email routing, and other configurations just to connect a single site.
+
+Appwrite Sites now supports **CNAME flattening**, so you can connect your domain by adding a DNS record with your existing provider instead of migrating nameservers.
+
+# Add a record, not a migration
+
+With CNAME flattening support, connecting a custom domain is just a DNS record away. Keep your existing provider, add a CNAME or ALIAS/ANAME record pointing to Appwrite, verify the domain in the Console, and your site is live with SSL automatically configured.
+
+This is especially useful for teams that rely on their DNS provider for more than just domain resolution. If Cloudflare handles your caching, security headers, or MX records, you no longer have to choose between that setup and Appwrite Sites.
+
+# How CNAME flattening works
+
+Standard DNS rules don't allow CNAME records at the root domain (`example.com`). Only subdomains (`www.example.com`) can use CNAME. CNAME flattening works around this: your DNS provider accepts a CNAME-like configuration at the root, resolves the target internally, and returns the corresponding IP addresses to the client.
+
+Depending on your provider, this goes by different names. Cloudflare calls it **CNAME flattening**, Route 53 uses **ALIAS records**, and some providers support **ANAME records**. The implementation varies, but the result is the same: your root domain can point to a hostname without breaking DNS standards.
+
+# Connect your domain
+
+1. Open your site settings in the Appwrite Console.
+2. Add your custom domain.
+3. Appwrite provides a DNS target.
+4. Go to your DNS provider and create the required record. Use a CNAME for subdomains, or an ALIAS/ANAME record for the root domain.
+5. Return to Appwrite and verify the domain.
+
+# Available now
+
+CNAME flattening support is available today on **Appwrite Cloud**. Head to your site settings, add a custom domain, and follow the updated DNS instructions.
+
+As always, we'd love to hear your feedback. If you run into any issues, join the [Appwrite community](https://appwrite.io/discord) and let us know.

+---
+
+You can now connect a custom domain to Appwrite Sites without changing your nameservers. Appwrite Sites now supports CNAME flattening and similar apex-domain features provided by modern DNS providers.
+
+Instead of migrating nameservers to Appwrite, you can add a DNS record with your existing provider, verify the domain in the Console, and go live. This works with CNAME flattening (Cloudflare), ALIAS records (Route 53), and ANAME records, depending on your provider.
