Why build a web app?

When people ask, “Why build a web app?” they generally look for a few key benefits. For beginners, a website typically does not reach the same functionality as a web app. A website only communicates unidirectionally, such as by displaying content. You can transform your website into a product by adding functionality with the help of a web application. And that's the main benefit: you construct a web app when you're seeking capabilities that a simple website won't allow you to have, which is why it's so advantageous to do so. You will then explore new market channels, user experiences, and possibly new revenue streams, among other opportunities.

What's the difference between a web app and a web page?

What is a web application?
A web application is software or program accessible using any web browser. Its front end is usually created using languages like HTML, CSS, and Javascript, which major browsers support. At the same time, the backend could use any programming stack like LAMP, MEAN, and others. Unlike mobile apps, there is no specific SDK for developing web applications.

Web Applications became prominent with the software as a Service (SaaS) movement.

Examples: Google Apps, Amazon, YouTube

What is a website?

A website with a single domain name consists of a collection of interlinked web pages that are accessible globally. An individual, business, or organization can develop and maintain it. There are many uses for the website.

A website is hosted on single or multiple web servers. IP addresses allow access via a network such as the Internet or a private local area network.

Examples: A restaurant's website where you can view the menu, opening and closing hours, comments, etc.

Why would you develop a web application?

Creating a web application is good for people and companies in many ways:

  • Reach more people: Web apps can be used on any device that has access to the internet, so they can reach more people.

  • Cost-effective development: Compared to developing native apps, developing web apps tends to be cheaper because you can build a single codebase that can be used on multiple devices.

  • Easy maintenance and updates: Web apps can be updated without needing users to download and install updates. This means that users always have access to the newest features and modifications without having to download and install updates.

Do web apps have any disadvantages?

While web apps offer numerous advantages, it's essential to consider potential drawbacks:

  • Limited offline functionality: Web apps rely heavily on an internet connection, meaning they might not work or provide limited functionality in offline scenarios.

  • Performance limitations: Compared to native apps, web apps may experience slightly slower performance, especially when dealing with complex animations or heavy data processing tasks.

  • Reduced device functionality: Web apps have access to limited device capabilities compared to native apps, potentially hindering their ability to leverage certain hardware features.

However, by working with a skilled development team like Imaginary Cloud, we can help you mitigate these disadvantages and create a web app that provides an exceptional user experience while minimising any trade-offs.

How to build a web app

Plan before you code

Before you dive headfirst into the code, you’ll want to create a plan for your web app. Your plan should include a high-level overview of your project, your technical approach, and the timeline for when you hope to launch your product. Testing a Minimum Viable Product, or MVP, means creating a basic version of your product that you can use to test the concept with colleagues or potential customers. It involves ensuring each component works well so that you can keep improving it until it reaches a point where there's no going back.

Despite the various tools available to designers today, creating successful digital products still requires much research. To begin, we have our Product Design Process (PDP) that guides us through this process. First, we conduct business analysis to determine the goals and expectations of the project; then, we move on to user research to understand what users want from a product. Next, we must ideate; that is, develop concepts for how to make these goals a reality. Afterwards, we move into the execution and technical assessment phases, creating designs and evaluating them for effectiveness.

This approach allows us to create digital experiences that meet users' expectations and desires when navigating a product. This will also contribute to attaining the business goals.

Select the right tech for web app development

Web application development is very similar to other software development life cycles. A solid team and initial set-out processes drive successful web app development.

You'll want to select the right technology for your project, depending on your business goals. There are dozens of different languages, libraries, and frameworks to choose from, so you want to make sure you're making an intelligent choice.

You should ask yourself:

  • What are your requirements? This includes the volume of traffic, user experience, and any security features you may need.
  • Who are your target users? You also need to consider who will be using your product. The more you know about your users, the easier it will be to select the right technology for the job.
  • What is your budget? Finally, you need to take your budget into account.

But when making a web app, people often use the following apps and tools:

  • Front-end development: HTML, CSS, and JavaScript are the technologies that are used to build the user interface (UI) and user experience (UX) of web apps. People often use frameworks like React, Angular, and Vue.js to build dynamic and interactive web apps.


If you ask your developer friend about React, they'll probably start gushing about how it brings user interfaces to life with its JavaScript library. React allows developers to build reusable UI components and efficiently update the user interface when data changes occur. It's like having a magic wand that instantly updates the webpage without reloading. Just think of all the time saved waiting for page refreshes! React's vibrant community and extensive ecosystem make it a powerhouse for building modern web applications.


If React is the cool kid on the block, Angular is the sophisticated, experienced guru. Angular is a framework that was made and managed by Google's people, and it has everything you need to build large-scale web applications.
It provides a robust structure for building complex interfaces and offers features like two-way data binding, dependency injection, and a powerful templating system. Angular takes care of the nitty-gritty details, allowing developers to focus on crafting exceptional user experiences.


Let's talk about Vue.js, the framework that sometimes feels like a hidden gem. Vue is often described as the Swiss Army knife of front-end development. It perfectly balances simplicity and power, making it a breeze to learn and use. Vue's elegant and intuitive syntax allows developers to build interactive web interfaces easily. And if you're worried about performance, fear not! Vue is renowned for its lightning-fast virtual DOM and seamless integration with existing projects.

  • Back-end development: Server-side programming languages such as Python, Ruby, Node.js, or PHP, combined with frameworks like Django, Ruby on Rails, Express.js, or Laravel, are commonly used to implement the logic and functionality behind web apps.

  • Databases: For storing and managing data, web app development often involves working with databases like MySQL, PostgreSQL, MongoDB, or Firebase.

  • Version control: Collaborative development is facilitated by version control systems like Git, enabling teams to manage and track changes to their codebase efficiently.

  • Testing and Quality Assurance: Automated testing frameworks and tools, such as Jest, Cypress, or Selenium, can be used to ensure the reliability and quality of web apps.
