Connecting a domain to your app

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.

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.

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. 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.

Setting up 301 redirects

A 301 redirect permanently sends visitors from an old address to a new one. Old links keep working, and search engines move your existing ranking over to the new address. For example, if you rename your /pricing page to /plans, a redirect sends anyone who opens the old /pricing link straight to /plans instead of a missing page. Base44 supports 2 types of 301 redirect:

• Path-level redirect: Sends one page on your app to another, such as /old-pricing to /pricing.
• Whole-domain redirect: Sends all traffic from one connected domain to another domain on the same app.

​

Redirecting one page to another

Path-level redirects send visitors from one page on your app to another. A path is the part of a web address that comes after your domain, such as /pricing, and usually points to a specific page. Use these redirects when you rename or move a page and want the old links to keep working. To add a path redirect:

1. Click Dashboard in your app editor.
2. Click Domains.
3. In the Page redirects section, click Add redirect.
4. In Source path, enter the old path, starting with /. For example, /old-page.
5. In Target path, enter the new path, starting with /. For example, /new-page.
6. Under Match type, choose how the redirect matches:
   • Single path: Redirects only the exact source path.
   • Prefix: Redirects the source path and everything under it, keeping the rest of the address.
7. Click Save redirect.

​

Redirecting a whole domain

A whole-domain redirect sends all traffic from one connected domain to another domain on the same app. The full path and query string are preserved, so old-domain.com/pricing goes to new-domain.com/pricing. Use it when you move your app to a new domain and want the old one to keep sending visitors to the right place. To redirect a domain:

1. Click Dashboard in your app editor.
2. Click Domains.
3. In the Custom domains section, find the domain you want to redirect.
4. Click the More Actions icon next to it and select Redirect domain.
5. Under Target domain, select the domain you want to send traffic to.
6. Click Save redirect.

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.
