Bubble is a low-code platform that enables users to build web and mobile applications without writing any code. One of the features of Bubble is the ability to create a subdomain, which is a unique URL that you can use to access your app. In this blog, we will guide you on how to create a Bubble subdomain and run an app on it.

Setting up a Bubble Account

Before you can create a Bubble subdomain, you need to set up a Bubble account. If you don’t already have an account, you can sign up for one on the Bubble website. After you sign up, you can log in to your Bubble account and access the dashboard.

Creating a New App in Bubble

Once you have logged in to your Bubble account, you can create a new app by clicking the “Create New App” button in the dashboard. After you create a new app, you will be taken to the app builder where you can start designing and building your app.

Setting Up Your Bubble Subdomain

To set up your Bubble subdomain, you need to go to the “Domains” section of your app builder. In this section, you can enter the subdomain name that you want to use for your app. Once you have entered the subdomain name, you need to click the “Save” button to save your changes.

If you don't already have a subdomain set up...

To create a subdomain with Bubble, you first need to set up a new A Record DNS with your DNS management company (where your domain is registered).

Enter the IP address for Bubble's public server and go to the app's Domain/Email tab to enter your new subdomain as [subdomain].[primarydomain].com (no https).

Deploying Your App to Your Bubble Subdomain

Once you have set up your Bubble subdomain, you can deploy your app to it. To deploy your app, you need to go to the “Deploy” section of your app builder and click the “Deploy to Live” button. After you deploy your app, you can access it by using your subdomain URL.

Testing Your Bubble Subdomain

Before you share your app with others, you should test it to make sure that it is working properly. To test your app, you can use the “Preview” feature in the app builder. This will allow you to access your app and test its functionality.

Sharing Your Bubble Subdomain

Once you have tested your app and confirmed that it is working properly, you can share your Bubble subdomain with others. You can share the URL of your subdomain with friends, family, or customers, and they will be able to access your app from that URL.

Managing Your Bubble Subdomain

After you have created and deployed your Bubble subdomain, you can manage it from your Bubble account. You can make changes to your app and deploy updates to your subdomain from the app builder. You can also monitor the performance of your subdomain and make changes to improve its performance.

Why You Should Use a Subdomain for Your App

If you're running an app, you want to make sure that it's accessible, organized, and secure. One way to achieve this is by using a subdomain for your app. Keep on reading, and we'll discuss the benefits of using a subdomain for your app and how to choose the right subdomain.

Better Organization and Branding

A subdomain allows you to separate and organize different sections of your website under a single domain. For example, you can use a subdomain for your blog, support section, or app. This not only helps with organization but also reinforces your brand, as users can easily identify different sections of your website by the subdomain.

Increased Security

Using a subdomain can also increase the security of your app. By separating your app into a subdomain, you can ensure that sensitive information, such as customer data, is stored and transmitted securely. This can also protect your app from security threats, such as cross-site scripting (XSS) attacks.

Improved User Experience

A subdomain can also improve the user experience by making it easier for users to access and use your app. By using a descriptive and memorable subdomain, users can easily find and access your app, without having to navigate through multiple pages on your website.

How to Choose the Right Subdomain for Your App

When choosing a subdomain for your app, it's important to consider several factors, including:

Consider Your Domain Name

When choosing a subdomain, it's important to consider the domain name you want to use. The subdomain should align with your brand and be easy to remember.

Make it Descriptive and Easy to Remember

A subdomain should also be descriptive and easy to remember. For example, if your app is a project management tool, you might use a subdomain like

Ensure it Aligns with Your Branding

Finally, your subdomain should align with your overall branding. This includes using a similar color scheme and font, as well as incorporating your brand's logo and messaging.
