What is a web application?

A web application is a digital tool you can access directly from a web browser. Unlike traditional software that gets installed on a computer, it generally lets users reach its features online, whatever device they are using.

Customer portal, management platform, booking tool, dashboard, tracking system or employee hub: web applications can take many forms and meet very different needs.

For a business, they make it possible to digitize processes, centralize information and build tools that fit the way it actually works. But in practical terms, how does a web application work, and how is it different from a website or a mobile app?

What is a web application?

The definition of a web application is fairly simple: it is software that runs through a web browser such as Chrome, Safari, Firefox or Edge.

The user typically goes to a web address and can then interact with the application. Depending on what it does, they might log in to their account, view or edit data, fill out forms, manage files, complete transactions or collaborate with other users.

The main difference from a website lies in the level of interaction. While a website is mainly used to present information and make it available, a web application lets the user carry out tasks and interact with data.

How does a web application work?

Behind an interface that can look simple are several components that communicate with one another.

First, there is the part the user sees, often called the front end. This is the interface they interact with: menus, buttons, forms, dashboards, charts and other visual elements.

Next, the back end handles the operations that happen behind the scenes. It can process user requests, apply the company's business rules, manage access or communicate with other systems.

Finally, a database can be used to store and organize the information the application needs to work.

When a user performs an action, these components work together to process the request and display the result in their browser.

Web application vs website: what's the difference?

A website and a web application are both accessed from a browser, which can easily cause confusion.

The difference lies mainly in their purpose.

A website is mainly used to share information. A company website, for example, can present its services, its team, its projects and its contact details.

A web application, on the other hand, allows for much more interaction. It is designed to let the user complete specific tasks.

A customer portal where clients can view invoices, download documents and track a project's progress is a good example. It doesn't just present information: it becomes a real work or service tool.

The line between the two is not always clear-cut, however. The same digital environment can include an informational section as well as features specific to a web application.

Web application vs mobile app

A mobile app is generally designed to run on a smartphone or tablet and often has to be downloaded from an app store.

A web application, by contrast, is accessed from a browser. All you usually need to use it is an internet connection and the right access.

This distinction can be a major advantage for some businesses. A web application can be designed to adapt to different screen sizes and be used on a computer, tablet or phone without having to build and maintain several separate apps.

The choice between a web application and a mobile app still depends on the features you need, the context of use and the needs of your users.

Web application vs traditional software

Traditional software is usually installed directly on a computer or on an organization's IT infrastructure. Using it can therefore depend on the device it is installed on, its configuration and the updates that have been applied.

Web-based software, on the other hand, is accessed through a browser. This approach can make the tool easier to reach for teams that work in different locations or use several devices.

Updates can also be rolled out centrally. Instead of installing a new version on each workstation individually, users simply access the version available online.

What are some examples of web applications?

Web applications exist in practically every sector. Some are aimed at the general public, while others are built specifically for an organization's internal needs.

A web application can take the form of a customer portal, an extranet, a project management tool, a booking platform, a request management system, a dashboard or a tool for managing employees, customers, suppliers or inventory.

A business can also build a web application to replace a collection of Excel files, forms, emails and manual tasks with a single, centralized environment.

What are the benefits of a web application?

One of the main benefits of a web application is its accessibility. Because it runs in a browser, authorized users can generally access it from different devices and locations.

It can also help centralize information. Rather than scattering data across several files and tools, the business can create an environment where the relevant information is grouped together and available to the right people.

A web application can also automate repetitive tasks. Steps that used to require manual data entry, back-and-forth emails or file transfers can be built directly into a digital process.

Finally, a well-designed application can grow with the business. New features can be added over time to meet new needs.

What is a custom web application?

Not every business has the same processes. Yet the software available on the market is generally designed to meet the needs of as many customers as possible.

That's where custom web application development comes in.

Rather than bending the company's ways of working to fit the limits of existing software, a custom solution is built around its processes, its users and its goals.

It can, for example, replicate a specific internal process, centralize information from different sources, automate certain steps or offer features unique to the organization's business model.

The goal is not simply to build a new tool, but to create a digital solution that truly fits the way the business operates.

Why do businesses use web applications?

As a business grows, its processes tend to become more complex. Information can end up spread across different software, spreadsheets, emails and documents.

This proliferation of tools can lead to duplicate data entry, errors, lost time and a lack of visibility into operations.

A web application can bring some of these processes together in a single environment and make it easier for information to flow between the people involved.

It can be especially relevant when a business wants to:

• automate repetitive tasks;
• replace manual processes;
• centralize its data;
• improve collaboration between teams;
• offer a portal to its customers, partners or employees;
• connect different systems;
• build a tool that matches its operations exactly.

The web application then becomes more than a technology tool: it directly supports the company's processes.

How is a web application developed?

Web application development starts well before any code is written.

The first step is usually to understand the need: what problem are we trying to solve? Who will use the application? What tasks should it make possible? Which systems will it need to communicate with?

Based on this analysis, it becomes possible to define the features required and to think through the user experience and the architecture of the solution.

Then come design, development, testing and deployment. Depending on the project, the application can keep evolving afterwards through new features and improvements based on users' needs.

This initial thinking is especially important in a custom project. An effective application should not simply reproduce an existing process digitally: it should also help determine how that process can be simplified or improved.
