Every Base44 app is live on a free built-in URL (myapp.base44.app) from the moment you create it. You can personalize that URL anytime, or connect your own custom domain to make your app easier to find, remember, and share.

​
Changing your Base44 app URL

Every Base44 app comes with a free built-in domain (myapp.base44.app) that you can personalize anytime. No DNS setup or payment required. To change your URL:
  1. Click Dashboard in your app editor.
  2. Click Domains.
  3. Click Edit URL under your app’s Built-in URL.
  4. Enter a new name for your link. For example: best-business → best-business.base44.app.
  5. Click Change to save.

Editing the URL of your app in Base44

Your new URL is live instantly, and your old link immediately stops working. Make sure to share your updated link with anyone who needs access.

​
Setting up a custom domain

A custom domain is your own web address, such as mybusiness.com, that people use to reach your app instead of the built-in Base44 link. For example, instead of sharing my-app-948908fb.base44.app, you can share mybusiness.com. A custom domain looks more professional and reinforces your brand every time someone visits.
Before you begin:
  • Custom domains are available on the Builder, Pro, and Elite plans.
  • Allow up to 72 hours for DNS changes if you use an external domain provider.
There are 2 ways to set one up: buy a domain, or connect one you already own. Whichever you choose, Base44 issues and renews your SSL certificate automatically once your domain is connected, so your app is always served securely over HTTPS. When you buy a domain, Base44 works with two providers, Wix and IONOS. Depending on your account, you may see one or both when you click Buy Domain. Use whichever you see, and follow the matching guide below.

Buy a domain with Wix

Buy a new domain through Wix. DNS and SSL are set up for you automatically.

Buy a domain with IONOS

Buy a new domain through IONOS. DNS and SSL are set up for you automatically.

Connect an external domain

Already own a domain? Point it to Base44 by updating your DNS records.

​
Sending emails from your domain

Once your custom domain is connected, you can send your app’s emails from it, such as support@your-domain.com, so they match your brand. See Sending emails from a custom domain to set it up.
