Web Application has become an important part of our daily life. We are surrounded with different web application in today’s digital life from a sending an email to the information share to different designs. You might be confused what is web application exactly- right? And what is the major difference between web application and traditional website or native application? Here, in this article, we will deep dive into the world of web application, with their definition, development, features, advantages and limitations and how can you develop one. Whether you are a just a curious reader, or a developer, or a business owner to start your own online business to solve the problems, this article will provide you the valuable information.
In simple word, a web application is a software program that is operated in web server and can be accessed through a web browser or their defined applications. In traditional desktop application, you need to install a application and run the software which is totally overcome by web application which you do not need to install and is stored on remote server and is delivered through internet. This allows you to access their application on any devices with an internet connection, where you are using a computer, laptop, tablet or Smartphone.
In earlier article we learn about what is Web Hosting and Domain Name. Here we will explore what is Web Application and difference between Website and Native Application.
Web Application vs. Website
Both web application and website are accessed through browser with the internet connection. However, there is identified deference between the two. Firstly, a website in general is a collection of static pages that displays various information such as about company, services they offers, blogs, and contact. And Web application is an interactive and dynamic site that allows its users to perform various tasks, input data, and to receive any customized outcomes.
For more understanding, Gadgets 360 – a new portal can be considered as a website because its main objective is to provide information. And a Google Docs is a web application as it allows its users to create, design, and store documents and information online.
- Functionality
Website is mainly focused on providing information. They are designed with static pages to provide various contents such as text, images, and videos to visitors. Users visit these types of websites and consume it contents and not necessarily interact with the provider.
Web Application are interactive allowing users to perform specific task such as editing document, making a purchasing anything stuffs, submitting form, sending emails, and so on. The contents and layout of website is often changed based on user input.
- User Interactions
In website, user’s interaction is limited to consuming contents. When any audience what to learn something, they visit the site read their contents clicking to the link.
Web application has higher level of interaction option. It allows users to create, edit the data, customize their experience, and interact with complex system.
- Complexity
Websites are simpler types of website and is simple to develop and maintain as they do not require high level back-end processing or dynamic content generation.
Web application can be complex based on the level of interaction. Therefore, it can be complex due to the combination of front-end and back-end development, database management, and server-side progressing. Also, the web application requires other activities such authentication, data storage, and real-time updates.
- Examples
A news portal is a website where various information are provided about news, updates, and politics or events.
An online project management tool is a web application that allows team to collaborate, assign tasks and track progress.
Web Application vs. Native Application
When deciding on developing an application, many businesses faces the confusion on selection on development a web application or a native application. Here are some major differences between these two types and helps you make decision to chose the better one for your business.
- Dependency on Platform
Web application operates through browsers. Therefore, it can be accesses anywhere on any devices. You only required is a safe browser and a internet connection.
Native application is develop for specific platform i.e. Android or iOS. As a user you need to download and install the application to your device and run the application. The application are optimized for the platform.
- Performance
Web applications are gradually improving its performance and speed. They are generally slower than native application because they mainly reply on a browser to run.
Native applications are built specifically for platform allowing taking full advantage of the device’s hardware and operating system. Therefore, it has better performance with smooth and quicker response.
- User Experience
Web application provides consistent user experience across various devices. But it may not access to all the devices with limited features on devices.
Native applications are more integrated experience working better on all the devices. They also support offline functionality which enable user to continue the app without an internet connection.
- Development and Maintenance
Web application development is generally faster and more cost effective because it only needs to develop for once and can be run on multiple platforms. Updates can be done instantly without requiring users to download a new version.
Developing a native application requires separate code-base for each platform. This can become a time consuming process but can offer more advanced features and better performance.
- Example
A remove.bg is online tools that allows users to upload the image and remove the background of the image and can easily download the result into your device.
Any mobile games are designed for android and iOS, with advanced graphic and access to your device is a best example of native application.
What is Web Application Development?
Web application development is the process of building, designing, and maintaining any web application. To create one you might requires various skills such as working of front-end, back-end development, database management, and user experience (UX) design. For that, a developer need to understand programming languages such as HTML, CSS, JavaScript, and other necessary frameworks to create responsive and interactive web application to meet their users needs and the objective of development to solve the problem.
Front-End Development
Front-End Development focuses on the part of user interact with. In another word, front-end mainly perform the tasks related to layout, design, and interactivity of the application. Developers’ uses different languages such HTML (Hyper Text Markup Languages), CSS (Cascading Style Sheets), JavaScript, and other languages to create visual elements and user interface that users sees on their screen.
Back- End Development
In Back-End, they perform the activity of server side of an application such as processing data, dealing with database and ensuring that the front end and the back-end communicate effectively. Common back-end technologies include sеrvеr-sidе languages such as Pythons, Rubies, PHPs or Java along with database management systems including MySQLs, Mongodb and Postgresqls.
Full-Stack Development
For full-stack development, a full stack developer may require. A full-stack developer is a person who has expertise in both front-end and back-end development. They are capable to create an entire web application from a start to end, and create a interface so a user can easily handle everything from a server management to database management.
How Does a Web Application Work?
We have break down it into two categories i.e. Web Application Architecture and Client server interaction and explained below briefly.
Web Application Architecture
Web Application Architecture is a represents the layout of all the software components and how they interacts. The various software components can be database, application, middleware, and browser. These all components work together and maintain interaction between these components.
Client Side
Client side is the Front-end of the web application which run in the user’s browser. It includes HTML, CSS, and JavaScript files which provide the structures, style, design, and behavior of the user interface. When a user interacts with a web application, the action is handled by front end code.
Server Side
It is a back-end of the web application. When user requests information or summits the data in the web application, the request is send to a server and the requests are processed through backend. The server –side logic is responsible for task like querying database, performing calculation and sending the appropriate response back to the client.
Database
The database is a place where the application stores the data through user accounts, product information, or transaction record. The server queries the database to recover and update the data when needed.
APIs
APIs (Application Programming Interfaces) allows various parts of the application to communicate with each other and with external services. Most common example is the payment gateway integration or social media integration. When a developer integrates these APIs with your web application for payment process, you can easily accept the payment which automatically transfers the amount to your account easily without using two application separately.
Client server interaction
Your browser sends a request to the web server when you input a URL in it or click on a link inside an application of the web. The server then processes this request which may require querying databases or making external APIs calls before sending its response back to the client. Later, the browser displays the received information as a website or interactive software.
What are Different Types of Web Applications?
There are various types of web application available and each has its own unique characteristics and the way of using. Here are some common types of web applications.
Static Web Applications
Static web applications provide pre-rendered contents to the user’s browser. It is developed using simple HTML and CSS codes without server-side processing. As the web application is simple and perform simple related tasks, web applications are fast and easy to set up. These types of web application are best for websites that do not requires user input.
Dynamic Web Applications
Dynamic Web application generates contents in the real time based on user interactions or data. Therefore, the application relies on both front-end and back-end technologies and may use database to store and retrieve information. Some popular web application’s examples are e-commerce platforms, social media networks, and CMS (Content Management System).
Single Page Application (SPA)
Under single page application (SPA), they load only one HTML page and update the content within dynamically based on user interaction. SPAs enhance user experience by making it smooth and fast through elimination of full page reloads. Some most popular example of single page application of SPAs is Gmail, Facebook and Twitter.
Progressive Web Applications (PWA)
Progressive web applications are the combination of web and mobile applications. They are developed using web technologies but also offers features like offline access, push notification, and device hardware access just like native applications. This is necessary for some types of web applications to make their application fast, reliable and more engaging building better user experiences.
Rich Internet Applications (RIA)
Rich Internet Applications (RIA) is other types of web application which offers a user experiences similar to desktop applications or software. However, they provide other advanced features such as drag-and drop- media playback, and real time updates. Rich Internet Applications is developed using technologies such as Adobe Flash, Microsoft Silverlight, or JavaScript frameworks.
Content Management System (CMS)
A Content Management System is another type of web application that allows users to create, manage, and publish content without requiring knowledge about coding. Some popular CMS platforms are WordPress, Joomla, and Drupal which is used by millions of website all over the world. If you are more interested to learn about CMS and various types, check out our article- Popular Content Management System to create your website.
Benefits of Web Applications
Learn various benefits of web applications over traditional desktop application and mobile applications. Here are some benefits you need to know.
Accessibility
One of the benefits of web application is the accessibility. As the web applications are hosted on web servers, user can access it anywhere using any device with an internet connection. This makes web application more versatile for users and can easily access their data or services everywhere they go.
Cross Platform Compatibility
As the web applications are run through browsers, it can be easily compatible with wide range of devices including desktops, laptops, tablets, and smartphones. In native applications, you need to develop the application separately for each platform i.e. Android and iOS. A single web application can serve all the users reducing the time of development and the cost.
No Installation Required
In desktop application, you need to install the application or software in your device and run the application. Here you do not need to install the application, you simply need to visit their URL and get access to the application. This also reduces the downloading issues, installment issues, and updates making the users easy to use from the start and right away.
Easier Maintenance and Updates
The web application is hosted on remote servers, therefore updates and maintenance is done through the server. When the user updates to the server, users can automatically receive the latest version without requiring downloading or installing everything. This makes easier to developer to add new features, fix bugs and ensure all user have access to the latest version of the application.
Scalability
Web Application is highly scalable. As your business grows or want add new features to your application or when there is increase in the demand of the users, you can easily upgrade your servers and handle more traffic without the need of users to install whole thing new. In other word, as your business grows, you can scale the requirement of your web application.

A web application’s user interface is also essential part when creating a web application because it influences a user’s interaction with it. Hence, you should always aim for a clear, easy-to-use and responsive design that varies with devices’ sizes. For this purpose you can use tools like Sketch, Figma or Adobe XD to create wireframes and prototypes
Step 4. Develop the Front-End and Back-End
As soon as the design of user interface is completed, it is possible to get on developing the both the front-end and back-end of the application. Creation of user interface through utilizing coding languages such as HTML, CSS or JavaScript refers to Front end Development while developing back end requires establishing server side logic, administering databases and even integrating APIs.
Step 5. Test the Application
Once the application goes live, it must be constantly monitored and maintained for smooth operation. This involves checking server performance, correcting any bugs that may develop, and introducing updates or new elements to the software. Regular maintenance will also allow the app to remain both safe and effective.
Conclusion
Web Application is a powerful tool for any businesses and individuals, offering wide range of benefits from accessibility and cross-platform compatibility to ease of maintenance and scalability.
