A web application is software that runs in your web browser. Businesses have to exchange information and deliver services remotely. They use web applications to connect with customers conveniently and securely.
The most common website features like shopping carts, product search and filtering, instant messaging, and social media newsfeeds are web applications in their design. They allow you to access complex functionality without installing or configuring software.
Web apps can be accessed from all web browsers and across various personal and business devices. Web apps don't require users to download them, making them easy to access while eliminating the need for end-user maintenance and hard drive capacity.
Web applications automatically receive software and security updates, meaning they are always up to date and less at risk of security breaches.
