Website vs. Web app

Web app vs Website

When it comes to developing a digital project, one of the first decisions is to choose between a website and a web application. While both share similarities, there are important differences that can influence the final decision.

The following aspects are explored, such as architecture, technologies used, performance, scalability, and security.

What is a Website

A website is a collection of web pages and related content that is hosted on a server and can be accessed over the Internet.

It is connected by a single domain name and is hosted on a server with a unique IP address.

It can be used for a variety of purposes, such as providing information about a company, offering products or services online, sharing multimedia content, and creating a community, among others.

Websites can have different structures and layouts, but generally include a home page, content pages that provide topic-specific information, contact and/or company information sections, and navigation sections that allow users to move from one page to another.

A website can be created using a variety of programming languages, such as HTML, CSS, and JavaScript, and can be managed and updated through a content management system (CMS) or through manual programming.

Types of websites

Websites can be classified according to the technology and tools used for their construction and operation:

  1. Static: they arebuilt using HTML and CSS, without dynamic user interaction or database.

  2. Dynamic: theyuse programming languages such as PHP, JavaScript, Ruby, among others, to create personalized content based on user actions.

  3. Database-driven: to store and manage information. These types of websites are more complex and generally require backendprogramming.

  4. E-commerce: they use e-commerce platforms, among others, to sell products online and manage transactions.

  5. User-managed content: allow content to be created and shared with other users. These types of websites often use content management tools (CMS) such as Contentful.

  6. Single page application: with a page that loads and updates dynamically as the user interacts.

  7. Progressive Web Applications (PWA): with features of mobile applications, such as the ability to work offline, access to the camera and microphone, and push notifications, among others. 

When to implement a website

It is necessary to evaluate the objectives, needs, and available resources to determine if implementing a website is a good idea and when is the right time to do it.

Some common reasons for implementing a website include:

  • A website can help a company or project to have an online presence and be found by potential customers or users around the world.

  • It can serve as a platform to display detailed information about the products or services offered by a company.

  • It can enable the sale of products or services online, which increases the company's reach and convenience for customers.

  •  It can be an effective tool to generate leads or customer prospects.

  • It can serve as a platform to create an online community around a specific topic or interest.

  • A well-designed and up-to-date website can help a company or project establish credibility and trust with users.

Advantages and disadvantages of a website

A website can be a very useful tool, but it is important to carefully evaluate its advantages and disadvantages before making the decision to build one. 


●  Easy access: they are accessible from any device with Internet access, without the need to download or install an additional application.

●  Easy to update: they are easier to update than applications, since changes can be made directly on the server and users will see them automatically.

●  Compatibility: they are compatible with a wide range of devices, operating systems, and browsers, which means they can reach a wider audience.

●  Lower cost: less expensive to create and maintain than developing and updating an application. 


●  Functionality limitations

●  Browser dependency: they are limited by the capabilities of the browser in which they run, which may limit the user experience.

●  Slower speed: theycan be slower than applications, especially with slower Internet connections.

●      Security: theymay be vulnerable to online security attacks.

What is a Web app

A web app or web application is a type of application that runs in a web browser and is accessed through the Internet.

Unlike mobile applications that are downloaded and installed on a mobile device, web apps run on a web server and are accessed through a web browser on any device with an Internet connection.

Types of web apps

Web applications can be classified according to their architecture, technologies used and functionalities:

  1. Monolithic: theyhave an architecture in which all the functionalities are in a single application. They are usually built with programming languages such as PHP, Java, or Ruby on Rails.

  2. Server/client: the client (web browser) and the web server work together to provide the functionality of the application. They are usually built with web development frameworks such as Angular, React, or Vue.

  3. Progressive (PWA): combine features of native applications and web apps. They can be used on any device, have a user interface similar to that of a native application, and can operate without an Internet connection. They are usually built using technologies such as HTML, CSS and JavaScript.

  4. Single page (SPA): all functionality is loaded on a single page. They are usually built using frameworks such as React, Angular or Vue.

  5. Scalable: they can be scaled to support a large number of users and increase performance. They are typically built using database and cloud computing technologies, such as AWS or Google Cloud.

  6. Service-oriented (SOA): they use web services to provide specific functionalities, such as payment processing and e-mail management, among others.    

When to implement a web app

A web app can be a good option for many projects where an accessible, upgradeable, easy to maintain and scalable application is required. However, it is also important to evaluate the limitations in terms of functionality and performance and compare them with other options.

The implementation of a web app depends on the specific needs and objectives of each project:

  1. When you need an application that is accessible from any device with an Internet connection.

  2. When easy updates are needed. As a web app runs on a web server, updates can be performed centrally and are propagated to all users automatically. This makes upgrades and bug fixes easier to implement and maintain.

  3. When easy maintenance is needed. Because a web app runs on a web server, developers only need to maintain a single version of the application, making maintenance and troubleshooting easy.

  4. When it needs to be multiplatform. They can be developed to be compatible with different operating systems and web browsers, which facilitates access for users with different devices and preferences.

  5. When it needs to be scalable. A web app can be scaled to support a large number of users and increase performance using database and cloud computing technologies.

Advantages and disadvantages of a web app  

Web applications have technical advantages and disadvantages that must be evaluated before deciding if they are the best option for a particular project.


  • Better functionality: they can offer a richer and more personalized user experience, as they can take advantage of device and browser capabilities.

  • Device integration: can be integrated with device hardware and software, such as camera or GPS, allowing for a more interactive experience.


  • Dependency on Internet connection, theyneed Internet connection to work, which can be a limitation in projects that require offline functionality.

  • Compatibility issues with different web browsers and operating systems, which may limit the user experience.

  • Difficulties in customizing theuser interface.

  • They require higher cost and development time than websites and may require advanced technical skills for development and maintenance. 

Differences between a Website and a Web app

While a website focuses on presenting static information and content to the user, a web app focuses on providing interactive and dynamic functionality, which implies a more complex client-server architecture, the use of advanced technologies and a focus on functionality and data storage.

These are their differences:

  1. Purpose: a website is primarily used to present static information and content, while a web app is used to provide interactive and dynamic functionality.

  2. Complexity: a website is simpler than a web app, as it may consist of one or several static HTML pages, while a web app is a more complex interactive application that may require business logic and a database.

  3. User interface: a website usually has a simple and straightforward user interface, while a web app has a more complex user interface that may include interactive elements such as buttons, drop-down menus and other controls.

  4. Technologies used: a website can be built using basic web technologies, such as HTML, CSS and JavaScript, while a web app requires the use of more advanced technologies, such as JavaScript frameworksand libraries, and backend tools to process and store data.

  5. Interactivity: while a website may provide some interactivity to the user, such as the ability to click on links or fill out forms, a web app focuses on providing an interactive and dynamic experience with technologies that update data in real time.

  6. Functionality: a website focuses on presenting information to the user, while a web app focuses on providing specific functionality, such as the ability to send emails, make online payments or share content on social networks.

  7. Data storage: a website is usually static and does not require data storage, while a web app can store and process data on a backend server.

  8. Updates: a website can be easily updated through a text editor and a web server, while a web app may require more complex updates through a version control system and a deployment process.

How to choose between a Website and a Web app

The choice between a website and a web app will depend on the specific objectives and needs of the project. These are the factors to take into account:

  • If the main objective is to present information or static content to the user, a website is the right choice. If the objective is to provide interactive and dynamic functionality, a web app is the best option.

  • If the application is simple, a website may be sufficient. If the application is more complex and requires interactivity and dynamism, a web app may be more appropriate.

  • If the application is simple and does not require interactive elements such as buttons or complex forms, a website is sufficient. If the application requires interactive elements and advanced controls, a web app is the best option.

  • A web app requires more resources and budget than a website. If you don't have the resources to build a web app, a website can be a good alternative.

  • If the project is expected to have a large scope and may need to be more scalable in the future, a web app may be a more suitable option than a website.
