What is the difference between a website and a web app?

A website primarily displays information - it's like a digital brochure.

Visitors read content, view images, and maybe fill out a contact form. A web application is interactive software that runs in the browser - users log in, input data, perform tasks, and see dynamic results. Examples: your business website is a website; your online banking portal is a web app. The line is blurring as modern websites add interactive features, but the key distinction is interactivity and user accounts. Web apps typically cost more to build because they require backend logic, databases, user authentication, and more extensive testing.
