Difference Between Web App vs Website

Here’s a breakdown of the difference between a web app and a website:

1. Purpose and Interaction:

Website: A website is like an online brochure or information centre. Its primary purpose is to provide content to visitors in a readable format. Interaction is limited to clicking links, reading, and viewing content.

Web App: A web app, short for web application, is interactive and functional. It allows users to perform tasks, input data, and receive customized results. Web apps involve user engagement beyond just reading information.

2. Functionality:

Website: Websites are static or content-based. They display information such as text, images, videos, and links. They may have essential interactive elements like contact forms or search bars.

Web App: Web apps are dynamic and offer functionality beyond displaying content. They can process data, perform calculations, store user information, and provide personalized experiences based on user input.

3. User Experience:

Website: User experience on a website is focused on navigation, readability, and accessing information quickly. The goal is to present content in an organized and visually appealing manner.

Web App: User experience in a web app is more interactive and task-oriented. Users can input data, customize settings, receive real-time feedback, and perform actions within the application.

4. Examples:

Website Examples: Blogs, news websites, company landing pages, and informational sites like Wikipedia are examples of websites.

Web App Examples: Online banking platforms, social media networks, e-commerce stores (like Amazon), project management tools (such as Asana or Trello), and online productivity suites (like Google Workspace) are examples of web apps.

5. Development and Maintenance:

Website: Websites are generally more straightforward and quicker to develop. They require regular updates for content but may not need complex programming or frequent maintenance.

Web App: Developing a web app involves extensive programming and ongoing maintenance. Web apps need regular updates for functionality, security, and user experience enhancements.

Types of Web Apps for Custom Web Applications

Here’s an explanation of different types of web apps for custom web applications:

1. Static Web Apps:

Static web apps are like digital posters or brochures. They display fixed content that doesn’t change frequently. Imagine a beautifully designed website showcasing information about a company, its services, and contact details. That’s a static web app!


  • Fixed Content: Static web apps have content that remains unchanged unless manually updated. For example, your company’s history, mission statement, and team members’ profiles.
  • Simple and Quick: They are easy to create and load quickly since there’s no complex processing involved. It’s like having a digital flyer that visitors can browse effortlessly.
  • Cost-Effective: Static web apps are cost-effective to host because they don’t require dynamic server processing or databases.
