What is a Web App?

The term “Web App” is a contraction of “Web Application” and refers to a software application that runs on a web browser. In other words, a Web App is a program that can be accessed through an internet browser without requiring the download or installation of additional software on the user’s device.

Web Apps are developed using web technologies such as HTML, CSS, and JavaScript, allowing them to run on various platforms, including desktop computers, laptops, tablets, and smartphones. Users can access Web Apps by typing the specific URL into their browser or through a link provided by a website.

Web Apps can offer a wide range of functionalities, from simple online tools like calculators or calendars to complex data management systems or business applications. They can interact with databases, enable user data storage, provide real-time collaboration features, and much more.

Some advantages of Web Apps include their ease of distribution and accessibility through the web, without the need to develop specific versions for each platform or operating system. Additionally, Web Apps can be easily updated without requiring users to install new versions since changes are made on the server and are immediately available to all users accessing the application through the browser.


The advantages of web apps

Web apps offer several advantages over traditional applications. Here are some of them.

  1. Multi-platform accessibility: Web apps are accessible through a web browser on various devices and platforms, including desktop computers, laptops, tablets, and smartphones. There is no need to develop separate versions for each operating system, simplifying the distribution and access to the application.
  2. Simplified updates: Since web apps are run on a remote server, updates and changes can be made centrally. Users do not need to worry about installing new versions or updates on their device, as changes are made on the server and immediately available to all users accessing the application through the browser.
  3. No installation required: Web apps do not require the download or installation of additional software on the user’s device. This means that users can access the application directly through the browser without having to manage software installation and updates.
  4. Ease of distribution: Web apps can be easily distributed over the internet, allowing users to access them wherever they have an internet connection. There are no complex distribution processes as in the case of traditional applications that require uploading to stores or distributing installation files.
  5. Scalability: Web apps can be easily scaled to handle an increasing number of users and requests. Since processing happens on the server side, it is possible to increase server resources or utilize cloud computing technologies to handle the workload more efficiently.
  6. Easy sharing: Web apps can be easily shared via URLs. You can send the application link to friends, colleagues, or clients, allowing them to directly access the application without having to install it.
  7. Real-time updates: Web apps can provide real-time updates and collaboration features. Users can work simultaneously on the same data or interact in real-time with others within the application.
  8. Reduced costs: Web apps can be more cost-effective to develop and maintain compared to traditional applications since they do not require specific development for each platform and can share code among different versions of the application.

These are just some of the main advantages offered by web apps. The choice to use a web app will depend on the specific needs of the project and user preferences.

How to create a web app

Creating a web app involves several stages of development. Here’s a general overview of the steps to follow to create a web app.

  1. Define the requirements: before starting development, it’s important to have a clear understanding of the requirements and desired functionalities for your web app. Define the application’s goals, identify user needs, and establish the key features you want to include.
  2. UI design: designing the user interface (UI) for your web app is crucial. You need to consider the visual appearance, navigation, and usability of the application. Tools like Adobe XD, Sketch, or Figma can be used to create UI mockups and define the application’s structure.
  3. Front-end development: the front-end refers to the visible and interactive part of the application that users see and interact with. Developing the front-end involves using web technologies like HTML, CSS, and JavaScript. HTML defines the page structure, CSS handles the appearance and layout, and JavaScript adds interactivity and dynamic functionality.
  4. Back-end development: the back-end refers to the part of the system that handles data processing, database operations, and other server-side functionalities. Various programming languages and frameworks can be used for back-end development, such as Python with Flask or Django, Node.js with Express.js, Ruby with Ruby on Rails, and many others. This will depend on your skills and personal preferences.
  5. Database implementation: if your web app requires data storage and management, you’ll need to implement a database. There are different types of databases to choose from, such as MySQL, PostgreSQL, or MongoDB. It’s crucial to design your database schema and use the appropriate query language to interact with the database from your back-end.
  6. Testing and debugging: throughout the development process, conducting regular tests to ensure that the application functions correctly and meets the defined requirements is crucial. Debugging resolves any errors or issues that may occur during development.
  7. Deployment: before deploying your web app, you need to set up an appropriate hosting environment. There are many hosting providers that offer services for web app hosting, such as AWS, OVH Cloud, Google Cloud, Heroku, Netlify, and many others.
  8. Maintenance and updates: once your web app is up and running, you’ll need to take care of ongoing maintenance and any future updates. Monitor the application’s performance, resolve any issues, and add new features or improvements as needed.

These are the general steps to create a Web App, which coincide with the steps to create a traditional app. Keep in mind that the process may vary based on project specifications, technologies used, and the developer’s skills. It might be helpful to acquire additional knowledge or seek web development consultations to support the creation of your web app.


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

The main difference between a traditional app and a web app lies in the platform they run on and how users access them. Here are some points of distinction between the two.

  1. Execution platform: a traditional app is a software application designed to run on a specific device, such as a desktop computer, laptop, smartphone, or tablet. It requires direct installation on the user’s device. On the other hand, a web app runs on the web, through an internet browser. It doesn’t require direct installation, but users can access the application through the browser on various devices and operating systems.
  2. Installation: traditional apps require downloading and installing a software package on the user’s device. This can involve complex installation procedures and requires storage space on the device. In contrast, web apps don’t require any installation. Users can access them simply by typing the URL in the browser address bar, and the application runs on a remote server.
  3. Updates: for traditional apps, users need to manually download and install updates on their device when a new version is available. Web apps, on the other hand, can be centrally updated on the remote server. Users don’t have to worry about installing new versions, as the changes made on the server are immediately available to all users accessing the application through the browser.
  4. Accessibility and portability: web apps are accessible from any device with a browser and an internet connection, regardless of the operating system. This makes them more portable and accessible compared to traditional apps, which can be limited to specific devices or operating systems.
  5. Distribution capability: web apps can be easily distributed over the internet without the need to go through app store approval processes or provide separate installation packages for different platforms. In contrast, traditional apps require distribution through specific channels like app stores, which may involve additional approval and compliance procedures.
  6. Device interaction capability: traditional apps often have more direct access to device features such as the camera, GPS, motion sensors, notification system, and other specific hardware functions. Web apps, on the other hand, may have limitations in accessing certain device features unless technologies like Web APIs or Progressive Web Apps (PWAs) are used to enable greater access to device functionalities.


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

The main difference between a web app and a website lies in the functionality and interactivity offered to users. A website typically provides static information and content accessible to users. It can consist of web pages that contain text, images, videos, and hyperlinks. Websites are primarily intended to provide information, present content, or promote a business or organization.

On the other hand, a web app offers interactive and complex functionalities similar to those of a traditional application. It can allow users to perform actions, interact with data, complete processes, or accomplish specific tasks. Web apps often include real-time interactions, data processing capabilities, collaboration features, and more.

In terms of purpose and objective, the main goal of a website is to provide information and content to users. It can be an informative site, a blog, an e-commerce site, or a news portal. The website can be static, with content that is occasionally updated, or dynamic, with continuously evolving content.

A web app, on the other hand, is designed to perform specific tasks or provide interactive services to users. It can be a project management application, a social media platform, an online booking system, a photo editing app, or any other interactive web-based application.

In terms of complexity and development, websites are generally simpler to develop compared to web apps. They often require web design and front-end development skills to create an appealing user interface and a good browsing experience. However, web app development complexity can require both front-end and back-end development, including data management, service integration, and other advanced features.

Regarding accessibility and updates, websites are generally accessible to all users through an internet browser and do not require any specific installation or access. They can be easily updated by adding or modifying pages and content.



Progressive Web Apps (PWAs) and Single-Page Applications (SPAs) are two web development approaches that offer advanced user experiences. Here’s a brief description of both concepts.

PWA (Progressive Web App)

PWAs are web applications that use modern technologies to provide an experience similar to native applications. They are designed to work on any device or platform, regardless of the operating system. They use a concept called a “manifest” to provide an app icon on the users’ home screen.

PWAs can also function offline or under unstable network connection conditions, thanks to the use of caching and progressive recovery technologies. They can send push notifications to users, similar to native app notifications. They are developed using web technologies such as HTML, CSS, and JavaScript, often supported by frameworks like React, Angular, or Vue.js. PWAs can be installed by users on their devices, adding an icon to the quick launch or app drawer.

SPA (Single-Page Application)

SPAs are web applications that operate within a single page, without the need to completely reload the page during user interaction. Interaction happens through asynchronous requests to the server, often using REST API calls or technologies like AJAX or WebSocket.

SPAs provide a smooth and responsive user experience, with seamless transitions between sections of the application. Content updates occur dynamically within the same page, without the need for traditional hyperlink-based navigation.

SPAs can utilize JavaScript frameworks and libraries like React, Angular, Vue.js, or Ember.js to simplify development and application state management. They can be optimized for fast initial loading by downloading only the necessary minimum for application startup and subsequently requesting additional resources as needed.

It’s important to note that PWAs and SPAs are not mutually exclusive: a PWA can be implemented as an SPA, leveraging the characteristics of both. PWAs often use SPAs as part of their technological stack to offer an advanced and interactive user experience.
