How to use custom domains in Bubble

To use a custom domain in Bubble, you connect your domain from a registrar (like GoDaddy, Namecheap, Google Domains, etc.) to your Bubble app by adding the DNS records Bubble gives you. You enter your domain in Bubble’s Settings → Domain/email tab, Bubble shows two DNS records (A‑record and CNAME), you paste them into your domain provider’s DNS settings, wait for propagation, and Bubble verifies it. After verification, your app loads on your custom URL instead of the bubbleapps.io one.

What “using a custom domain” means

Bubble hosts your app, but your domain name is managed by your domain registrar. To “connect” them, you tell the registrar where your Bubble app lives using DNS records:

• A‑record → Points your root domain (like myapp.com) to Bubble’s IP.
• CNAME → Points your www version (www.myapp.com) to Bubble.

Step-by-step setup in Bubble

• Go to Settings → Domain/email.
• In the domain field, enter your domain (example: myapp.com).
• Bubble instantly shows the DNS records you must add:
  • A‑record: host “@” → points to Bubble’s IP (Bubble shows the exact number).
  • CNAME: host “www” → points to app.bubble.io.

Do not change the type of records Bubble provides. Add them exactly as shown.

Adding DNS records at your registrar

Open your domain provider’s DNS management panel and add the two records exactly as Bubble gave you. Example format (do not copy values — use the ones Bubble gives you):

// Example only!
// A record
Host: @
Points to: 54.xxx.xxx.xxx

// CNAME record
Host: www
Points to: app.bubble.io

Save your changes. DNS usually takes from a few minutes up to 24–48 hours to propagate.

Final verification in Bubble

• Return to Bubble → Settings → Domain/email.
• Click “Check my settings.”
• When DNS is propagated, Bubble marks the domain as “Connected.”

From that moment, visiting your custom domain loads your Bubble app.

Common issues to avoid

• Having multiple A‑records for the root domain breaks the connection — keep only Bubble’s.
• Do not use CNAME on the root domain; only on “www.”
• Do not proxy the A‑record through Cloudflare unless you know how to configure it; leave it “DNS‑only.”

Once connected, your Bubble app works the same — only the URL changes.
