How to set up domain mapping in Bubble

To set up domain mapping in Bubble, you connect your custom domain (like myapp.com) to your Bubble app by adding Bubble’s required DNS records inside your domain provider (such as GoDaddy, Namecheap, or Cloudflare). Bubble gives you two DNS records: one CNAME for www and one A‑record for the root (yourdomain.com). After you add them, you click “Check my settings” in Bubble and wait for them to propagate.

What You Actually Do in Bubble

You set this up in the Settings → Domain / email tab. When you type your custom domain into the field (for example: www.myapp.com), Bubble shows you two records you must copy into your registrar:

• A‑record pointing the root domain (myapp.com) to Bubble’s IP address.
• CNAME record pointing www to app.bubble.io.

What You Do at Your Domain Provider

Inside your domain DNS panel, you create exactly what Bubble shows:

• A‑record for @ with the IP Bubble provides.
• CNAME for www with value app.bubble.io.
• Make sure you remove any old A‑records or AAAA‑records pointing somewhere else.

DNS changes usually take from a few minutes to a few hours.

Final Step

Go back to Bubble → Settings → Domain / email and click Check my settings. When DNS has propagated, Bubble confirms and your live app loads on your custom domain.

// Example DNS entries (values must match what Bubble shows for your app)
Type: A       Host: @       Value: 123.45.67.89
Type: CNAME   Host: www     Value: app.bubble.io
