Technical overview

What is bubble.io built on?

Bubble.io is constructed using a mix of JavaScript-coded modules, CSS, and HTML, which come together to form a functional node.js application. Bubble has its own language based on JSON. This technology allows Bubble.io to run smoothly and efficiently.

Furthermore, Bubble.io is hosted on AWS, a powerful cloud platform. This means that the system is always being monitored and improved behind the scenes. As a result, you can expect your Bubble-powered apps to have an impressive 99.9% uptime. This infrastructure also lets you easily increase the computing power of your apps. And rest assured, AWS employs numerous security measures to keep your apps and data safe.

It's worth noting that while Bubble.io is hosted on AWS, developers interact with Bubble's interface and tools directly. There's no need for users to have an AWS account or interact with the AWS environment. This integration with AWS happens mostly behind the scenes, Bubble handles database management and manipulation within its platform. If you prefer, you can connect an external database like Xano or Firebase to your Bubble app.

Where is bubble.io hosted?

Bubble.io is hosted on Amazon Web Services (AWS), a reliable cloud computing platform. AWS provides a secure and scalable infrastructure that ensures high performance and availability for Bubble applications. Bubble's main cluster applications are hosted on AWS West Region (Oregon, US), but this can be customized if you're on a Dedicated Plan. It's important to note that Bubble apps cannot be hosted on-premise, meaning you can't choose your own server for hosting.

How does the Bubble.io platform work?

Bubble.io is a no-code platform, and, as such, it lets you create web applications without the need for traditional coding.  As a full-stack solution, it covers all the essential components an app needs to be fully functional: user interface (front-end) design, back-end logic, and hosting environment.

With Bubble.io, a no-code developer designs user interfaces through an intuitive drag-and-drop approach. Then it’s time to define data types, create data fields, and establish relationships between them. To establish logic workflows, you have to visually map out the sequence of actions the app should execute, like user registration or data manipulation. Furthermore, Bubble.io lets you seamlessly integrate external services and APIs. This means you can connect your app to various tools and resources, enhancing its functionality.

Technically speaking, Bubble.io combines modules coded in JavaScript, CSS, and HTML into a functional node.js application. This means that Bubble.io follows trusted and accepted web standards, so, if the standard capabilities of Bubble.io are not sufficient, developers can build custom solutions in JavaScript.

‍

Features and capabilities

Bubble Features

Drag and drop‍

Bubble.io's drag-and-drop feature allows users to create applications visually without requiring code. The feature is based on the concept of "What You See Is What You Get" (WYSIWYG) editing, meaning that users can design and manipulate their application's user interface exactly as it will appear to their end-users.
Users can drag and drop elements such as buttons, text, images, forms, and other user interface elements onto the design canvas. They can then customize the elements' properties and behaviors using a variety of settings, without writing a single line of code. These elements can be grouped and organized to create complex workflows and logical sequences that form the backbone of an application.

‍

‍‍

Bubble backend workflows‍

In Bubble.io, the Workflow feature allows you to automate processes by setting up a sequence of events and actions. Each step in the sequence has an event that triggers it and one or more actions that occur when the event happens.

There are many pre-defined events available, and you can also create custom events to make your application more tailored to your needs. Once you've set up the event, the associated actions will be triggered. You can choose from predefined actions or create your own custom actions.

‍

‍
Bubble encrypted database‍

One of Bubble.io's key features is its encrypted database. When working with data in your app, there is a continuous flow of communication between the user's device and the Bubble server. This communication is encrypted at all times to ensure that any data sent between the user's device and the server remains private.

For instance, if a user inputs personal information like their name and date of birth, that data is encrypted while being sent to the server and while it's stored on the server. This means that the data is protected from unauthorized access and stays secure at all times.

‍

Bubble app deployment and hosting‍

When it comes to server maintenance, infrastructure, or operations, Bubble.io can take care of the deployment and hosting for you in a safe and secure way.

Bubble also offers a dedicated hosting plan. This means that your app can be hosted on infrastructure that's isolated from other Bubble customers. Your app would run on dedicated servers, which can provide enhanced reliability and the ability to scale as required.

Bubble takes care of all the server setup, software installation, and monitoring, freeing you from the burden of managing these tasks yourself. This can be especially beneficial for those who want to focus on developing their app without the added complexity of managing the underlying infrastructure.

‍

‍

Bubble API connector‍

Bubble.io’s API connector is probably their most important plugin on the market. As the name suggests, it lets you connect to other apps and services to share actions and data. Bubble's API Connector enables you to seamlessly integrate external APIs with your Bubble app.

With this feature, you can easily call external applications or utilize custom logic developed outside of Bubble. This allows for greater flexibility and expands the capabilities of your Bubble application beyond its native functionality.

‍

‍

Bubble integrated debugger‍

Bubble.io has an integrated debugger to help users easily identify and correct errors in their applications. With this tool, users can see each element's performance, and the data being passed, and diagnose any issues in real time. The debugger streamlines the process of identifying and fixing issues, allowing users to focus on enhancing their application's functionality.

Bubble.io use cases: When to use Bubble?

‍Bubble for MVP development‍

Many people use Bubble.io to create MVPs (Minimum Viable Products), a basic version of a product or service that is developed with the primary goal of testing and validating its feasibility in the market.

By starting with a no-code MVP, and building it with a no-code platform, you can avoid the risk of investing a significant amount of time and resources in developing a product that may not meet the needs of your target audience.

When building an MVP on Bubble, you need to define your MVP and determine the core features that you need to include from the start. If your MVP needs to be a native app from the outset, you may need to consider that you’ll have to take some additional steps. However, for most basic MVPs, Bubble can be a reliable solution.

‍

‍
Bubble for workflows automation‍

Many businesses can benefit from custom software that helps them automate their processes.

While it is common for small and medium-sized enterprises (SMEs) to utilize various off-the-shelf software as a service (SAAS) subscriptions, there are benefits to using custom software built with Bubble.io.

With custom software, SMEs can tailor the platform to their specific needs and requirements, allowing for a more efficient and effective workflow. Additionally, custom software can eliminate the need for multiple SAAS subscriptions, potentially saving them money in the long run.
