Custom Domain

Connect your AI apps to your own domain for professional branding

Custom domains allow you to publish your CalStudio AI apps on your own branded domain, providing a seamless experience for your users without any CalStudio branding.

Overview

With custom domains, you can:

• Host your AI apps on your own domain (e.g., chat.yourdomain.com)
• Maintain complete brand consistency
• Build trust with professional URLs
• Improve SEO and discoverability

Prerequisites

Before setting up a custom domain, ensure you have:

CalStudio Pro Plan

Custom domains are available on Pro plans and above

Domain Ownership

A registered domain with DNS management access

Setup Process

Step 1: Create and Launch Your App

1. Follow the Quickstart Guide to create your AI app
2. Configure and test your app thoroughly
3. Click “Launch” to make it live

Step 2: Configure Custom Domain

1. In your app’s dashboard, locate the Status section
2. Click “Publish” → “Custom Domain”
3. Enter your desired domain:
   • Root domain: yourdomain.com
   • Subdomain: chat.yourdomain.com (recommended)

Step 3: Configure DNS Settings

CalStudio will provide DNS records based on your domain type:

Subdomain (Recommended)

For subdomains like chat.yourdomain.com:

1. You’ll receive a CNAME record from CalStudio
2. Add this record to your DNS provider:
   Type: CNAME
   Name: chat (or your chosen subdomain)
   Value: [provided-by-calstudio].calstudio.app
   TTL: 3600 (or default)
   

3. Save your DNS changes

Subdomains are easier to configure and don’t affect your main website or email settings.

Step 4: Verify Deployment

1. Wait for DNS propagation (usually 5-30 minutes for CNAME, up to 48 hours for NS)
2. Visit your custom domain
3. Your AI app should now be live!

Use DNS Checker to verify your DNS records have propagated globally.

SSL Certificates

CalStudio automatically provisions and manages SSL certificates for all custom domains using Let’s Encrypt. Your app will be served securely over HTTPS.

Best Practices

Use Subdomains

Subdomains are easier to manage and don’t affect your main website

Troubleshooting

Domain not working after 48 hours

• Verify DNS records are correctly configured
• Check for typos in the domain name
• Ensure no conflicting A or AAAA records exist
• Contact support with your domain details

SSL certificate errors

• CalStudio automatically handles SSL certificates
• If using Cloudflare, ensure proxy is disabled (DNS only)
• Allow up to 24 hours for certificate provisioning

Email stopped working (root domain)

• This occurs with NS delegation
• You’ll need to recreate MX records in CalStudio’s DNS manager
• Consider using a subdomain instead to avoid email issues

Want to remove custom domain

• Remove the domain in CalStudio dashboard first
• Then update/remove DNS records at your provider
• Your app will revert to the CalStudio subdomain
