What’s the Difference Between a Website vs. a Web App?


A website, anchored by a domain name, is an interconnected collection of web pages featuring diverse content like text, audio, video, and documents. While traditional websites offer static visual and text content, modern advancements enable the creation of dynamic, app-like news websites with interactivity beyond static pages. Dynamic websites employ modern design tools, CSS, JavaScript, databases, and advanced programming for backend user interaction. They can tailor content based on factors like time or location. Regardless of the website type, populating it with high-quality content is crucial to attract and retain visitors.

Web Apps

On the other hand, web applications are browser-accessed software that doesn’t require downloading, unlike mobile or desktop applications. They are developed using languages and technologies similar to those used for website creation but involve more complexity due to data storage and manipulation needs. Common examples include web portals for various tasks, such as expense tracking, class registration, advertisement creation, file scanning and conversion, and more.

These kinds of tasks mostly involve server-side processing, rendering the apps dynamic. Businesses planning to develop a web app must offer a valuable service to users. Otherwise, it won’t be utilized. The scalability, independence from app store approval, support for modern browsers, and cross-platform compatibility make web apps a favored choice for businesses.

Essential Differences

  • Websites primarily act as a source of information where users or visitors can view, read, or listen to content without interacting or manipulating it.
  • Web applications, however, engage users through interactive content and provide services like data manipulation, often seen in forms and other interactive elements.
  • Websites, though increasingly interactive due to modern web development standards, are relatively simple to build, essentially being collections of static web pages.
  • Web applications, in contrast, are more complex due to backend services, user-level variations, data processing capabilities, and advanced security measures.
  • Websites are often available to the general public. Both registered, and unregistered users are provided with the same quality of user experience.
  • Web apps usually require user registration and authentication. They offer customized services based on individual user needs, including banking apps that provide a unique experience for each user based on their personal banking information.

Types Of Custom Web Applications To Consider

Web apps can greatly benefit businesses. They can boost growth, simplify tasks, and enhance organization. Let’s explore various custom web apps your business might benefit from.

E-Commerce Applications

A digital store can simplify shopping for your customers if you run a business selling goods. Online shopping is growing rapidly, becoming an essential part of everyday life.

Adding e-commerce capability to your existing website is straightforward. With most online shoppers using mobile devices, e-commerce tools can help improve customer interaction and boost sales. A well-designed, online shopping custom web application with easy-to-use navigation, detailed product images and information, and a user-friendly shopping cart encourages customers to make a purchase, particularly when they’re on the move.

Although pre-made software solutions exist, they’re often basic and limited. Developers can build tailor-made e-commerce tools capable of handling complex tasks like intricate sales or return policies or managing multiple warehouses. This custom software can be developed from scratch, or current e-commerce platforms can be adjusted to suit your unique business needs.

Portal Web Applications

Custom web apps frequently use online portals due to their versatility. Businesses often use them internally and offer employees a self-service platform for work-related and administrative information. Apart from that, clients, customers, and patients can also access info using these portals. Sometimes, they serve both employees and customers. These portals often feature email, search engines, chats, and forums while requiring registration for access.

It alludes to a practical solution for businesses requiring strict control over user access to specific content. They can also easily limit certain functionalities. Portals are used in educational institutions, online banking, insurance, healthcare, and corporate sectors.

For businesses offering services like coaching or courses, portals through custom web application development solutions are a more efficient way to manage tasks than handling numerous emails and attachments. A portal lets clients see and complete action items at their own pace. It also simplifies discussions on individual tasks and quickly shows completed items.

CMS Web Applications

A Content Management System (CMS) web app allows small businesses to add and update content on their site effortlessly. It eliminates the need for advanced web development skills. Today, simple, few-paged websites don’t cut it. Regularly uploading blog posts, images, videos, reports, and white papers helps your site stay competitive and noticeable to search engines.

CMS custom web apps are user-friendly and cost-effective, perfect for firms looking to keep their website current without technical know-how. A CMS is a smart option if your business involves multiple users modifying content and requires tracking of these changes.

Animated Web Applications

Companies use animated tools through custom web app development to grab user interest and underscore key points. Some, such as GIFs, might be non-interactive, while others can be.

These dynamic web tools pave the way for innovative designs fitting for creative directors and designers. However, the tech used isn’t seen as the best for search engine optimization.

Web Application Technology Stacks

Web application tech stacks are the software tools, frameworks, and libraries web developers use to create custom web apps and websites. The tools are frequently packaged into multipurpose libraries, known as “bundlers,” for use in various projects.

The following are the most common web application technology stacks:

  • PHP, or PHP: Hypertext Preprocessor, is a scripting language primarily used for web development. It can be embedded into HTML or JavaScript code or in separate files.
  • Python is a versatile programming language utilized in web development. It supports various programming styles and has a clear syntax. Python’s extensive standard library includes modules for common tasks like database connection and email sending.
  • Ruby on Rails, called RoR, is a web framework written in Ruby. It offers default structures for handling HTTP requests, HTML templating, and caching responses. Ultimately, it makes this framework a comprehensive full-stack solution.
  • The LAMP Stack, which stands for Linux, Apache, MySQL, and PHP, is a popular choice for high-traffic websites. It is known for its scalability and stability. Many WordPress sites and large-scale CMS platforms like Drupal and Joomla utilize this technology stack.

Simple vs. Complex Custom Web Applications

Small businesses benefit from simple web apps that help manage content or promote products online. At the same time, larger firms or corporations often use complex, custom web apps to meet their expanding integration needs or for scalable software solutions.

What differentiates a simple web app from a complex one?

Take a static web app, for instance. It’s a simple web app with limited content and flexibility, perfect for showcasing professional portfolios or digital resumes. Nevertheless, developers or web administrators usually have to step in to alter these apps.

Dynamic web apps are more complex. They use databases to present data and generally come with a control panel (CMS) for management. Various programming languages can be used to create these, making content updates easy and facilitating features like discussion forums.

To categorize a web app as simple or complex, one must assess the user functionality needs (for both internal and external users), the current and future potential for integration and APIs, the scalability requirements in line with the company’s growth, and the range of browsers and devices on which the software will operate. Let’s explore them one by one.

User Functionality Requirements

When creating a bespoke web application, you must consider user-oriented features. Suppose the app is intended for internal use. In that case, factors like user roles, access rights, file transfer, client interaction, and task organization should be factored in.

Generally, software or tools through custom web application development become intricate when designed for internal and external usage. Complex features might enable customers to set up profiles for order tracking or allow users to book or modify appointments online.

For intricate web apps that let external users make profiles and save private data, developers need extra precautions. They must ensure their data is safe while preventing external users from accessing sensitive app parts, such as payment details or login credentials.

Integration & API Capabilities

The main difference between basic and advanced web apps is their ability to connect with other software and APIs from different databases or sites. An integration lets two apps interact, while an API, or “Application Programming Interface,” creates a real connection between them.

Basic web apps can work with Google Fonts, Mailchimp, and Shopify, among others. Advanced web apps can link with customer management systems or business/client online portals.

Application Scalability

The ability of a custom web application to scale impacts its complexity or simplicity. An app’s scalability becomes crucial as IT structures and user request increases. Suppose businesses opt for apps that can’t scale. Then they might encounter issues, including limits on the application server, wrong server settings, ineffective caching, slow or bad database searches, complex database designs, and insufficient memory and processor power.

Small firms with basic internal process requirements and no user growth plans find simple apps fitting. However, before deciding how much an app needs to scale, organizations should consider their growth trajectory and existing information technology setup. It includes but is not limited to the age of their software and the requirement for data sharing across departments.

Browser Versions & Devices

Coders must identify which devices, versions, and web browsers their custom web apps should operate on. Many browsers are available, but most people prefer a few popular ones.

In 2020, Google Chrome, Apple Safari, and Mozilla Firefox were the most used browsers. Backed by Google’s immense influence, Chrome is known for being user-friendly. Firefox, on the other hand, is popular for its speed and efficiency. Safari, the default browser on Apple devices, has a wide user base. So, their support is essential, covering a large user population.

Although, it is still necessary to keep an eye on shifting trends in browser use. For instance, Microsoft’s Internet Explorer, once a top choice, has lost its appeal since Microsoft no longer supports Internet Explorer Version 10. And making new custom web applications compatible isn’t advisable.

Web app coders can guide you on the best browsers and devices to prioritize. Some browsers work only on specific operating systems. Coders can verify that your app delivers a seamless user experience across the most prevalent browsers and devices your audience will use.

Back-End Frameworks, Front-End Frameworks & Hosting Solutions

On the other hand, applications that experience high user traffic, possess intricate user interfaces, and require integration with external systems incur higher development costs.

Custom Web App Development Process Flow

The custom web app development cycle follows the SDLC model with key stages, which, if missed, can lead to unexpected outcomes. Quality and productivity are maintained by being detail-oriented and adhering to set regulations. The development cycle includes requirements outline, time and budget estimation, design and conception, coding, testing, deployment, and post-production. Each stage interrelates and demands effort, time, workforce, and cost.

  1. The initial step is requirements analysis, where the organization identifies the final objectives and required documentation. It paves the way for categorizing tasks, assessing their complexity, and calculating expected time and cost.
  2. The conception stage, the second step, provides the development guide and design specifics of the custom web application. Essentially, this step organizes tasks and highlights their dependency before actual development begins.
  3. Testing generally happens alongside development to minimize bugs and prepare the product for user acceptance. Deployment is often considered to be the final stage before the application is made available to the general public.
  4. Post-production is crucial. It involves continuous maintenance and support to enhance user experience. Besides that, it necessitates understanding application behavior, analyzing user feedback, and working on updates.

The most successful custom web application projects use continuous software development lifecycle models like Agile. These kinds of methodologies prioritize incremental completion of each stage and enable firms to deliver productive solutions tailored to user needs.

Agile supports new solutions through flexible iterations and demands only initial planning while allowing for experience-based adjustments. It’s suitable for both new and ongoing projects. Alternatively, the Waterfall methodology can be used for smaller, well-defined projects where stages are sequentially executed. However, keep in mind that given the complexity of custom web application development, Agile methodology is often preferred.

Benefits of Custom Web Application Development

While the Apple App Store & Google Play Store boast an impressive collection of apps and downloads, native mobile apps may not always be the optimal choice for businesses.
