Introduction

One of our my clients from 2011 visited us. He has a Single Page Application and wanted to scale his online visibility to match the growing business requirements and identify potential market opportunities. But he wasn’t sure about the right tech stack that would be ideal for his business. We suggested him to choose custom web app development.Here’s how we guided him on web application development to give you precise clarity on choosing the right tech stack for his product. If you are in the same dilemma, then this blogpost will be a helping guide for you. Let’s explore and understand all the aspects of web app development in 2025.

The first thing to ensure is if we are on the same train on the difference between a web app and a website.

What’s the Difference Between Web App vs Website?

The significant difference between a web app and a website is that a website primarily delivers static information; you can see and read that information but not alter it. Whereas a web app focuses on user interaction which means everything you see is interactive; you can not only read it but manipulate the data on the page. The interaction is more of a click-to-get format; you click on the button and submit then the page delivers the output/response.

Everything has evolved with the change in time, and so have the websites. Today, on every website, you would see at least a pinch of interactivity into it, whether it is a form, a google map, or any other interactive components. A traditional website contains a minimal set of interactive components, but it is a website indeed.

Generally, A web app can include an online banking app, online store, social networking sites, or other similar platforms. Web apps connect with users via chat apps, blogs, or feeds based on user preference.

This was a basic overview of a web application and a website, but how can we move forward without knowing the difference between the two? So, to do that, let me give you a comparison table and help you better understand the difference:

Now that we have completed the difference, you must know why I covered this topic. Well! The answer is “interaction” one term that sums up a web application. To give you a better understanding of this, let us take you to the web application architecture.

Web Application Architecture: Components and Types

A web application architecture is a three tier-architecture that ensures how the interaction takes place between the three software components (application, middleware, and database.) The architecture explains how data is delivered via HTTP and ensures that both the client and server sides can understand the data request. Also, it verifies user requests’ data validity, creates and manages records, and simultaneously provides permission-based access and authentication.

The interaction process within a web application architecture occurs amid three components called the components of web application architecture. Let us have a look at them.

Components of Web App Architecture

A web application architecture mainly comprises three core components and they work hand-in-hand to interact with each other and, thereby, are responsible for the functionality of your application and the user experience.

• Web Browser (client-side): The client-side or the front-end component is the key component that interacts with your user and receives input. It also manages presentation logic and user interaction with the app.
• Web Server (server-side): The server-side, or the backend component, manages business logic. It processes user requests by routing them to the right component and managing the entire application operations. A web server can also run and oversee requests from various clients.
• Database Server: The database server provides the required data for your app. The data server handles data-related tasks. In a multi-tiered architecture, they can manage business logic with the help of stored procedures.

This was the basic overview of the three components of a web application architecture components. Let us now explore a few frameworks that can contribute to the development phase based on the component they can help you with:

Client-Side Web App Development Frameworks

A client-side web app development framework is responsible for your app’s user experience concerning visibility and layout. So, if you wish to give a thrilling experience to your users, your front end must be exceptional. Below are a few technology stacks that can assist you with client-side innovative custom web app development.

• HTML: HTML is a simple solution for designing the skeleton of your web application. You can use HTML to structure web page contents using a series of page elements.
• CSS: CSS assists you in separating website content and layout for sites developed using markup languages. You can use CSS to define a style for elements and reuse them multiple times across various sites.
• JavaScript: JavaScript allows you to create attractive interfaces to deliver a better UI/UX experience. Being on the client side, JS reduces the server load as well.
• JS React: React.js allows you to make single-page application (SPA) centric UI. You can also handle the view layer of your web apps with React.js and create reusable UI components.
• JS Angular: AngularJS allows you to use HTML as a template language and extend HTML’s syntax to express your app’s components clearly.
• Vue JS: If you want to build classic web interfaces and SPAs, then Vue.js is perfect. Vue.js provides a declarative and component-based programming model that helps you efficiently develop simple and complex UIs, and you can hire Vue.js developer to leverage their expertise for even more advanced solutions.
• JS Backbone: Backbone.js is a perfect option to develop SPAs and front end much faster. You can also design and structure the client-side apps that run in a web browser via Backbone.js.
• JSNode: Node.js is mainly used on the client side and in the browser; Node.js permits you to implement all sorts of dynamic interactions on the page.
• Ember JS: Ember.js is an open-source, free JavaScript client-side framework for developing web applications. It allows you to build client-side JS apps by delivering a complete solution with data management and an application flow.

This was the tech stack for the client-side component of the web application architecture. Let’s see what server-side component offers us for our custom web application development.

Server-Side Web App Development Frameworks

The server-side component of your web app architecture is responsible for receiving user requests, performing business logic, and delivering the required data to the front-end systems. Your web server component involves servers, databases, web services, etc.

Here’s list of best web app development frameworks that you can use for your custom web application development is given below:

• Ruby on Rails: Time efficiency is one of the most significant advantages of Ruby. It can be used to write CGI scripts and you can also embed it into HTML. One of the most considerable enterprise web app development framework.
• PHP: PHP is a popular all-purpose scripting language that is quick, adaptable, and practical, making it ideal for web development. PHP is an effective tool for developing dynamic, interactive web pages.
• Java: Java is a general-purpose programming language for creating desktop, web, and Android applications. The first choice of organizations is to hire Java developers while building enterprise-grade applications as Java offers outstanding stability and security.
• Python and Django: Python is adaptable, cutting-edge, and requires little training. This programming language is used for developing backend websites. Python and its framework Django are capable of handling backend development chores well.
• Go: Go is an open-source, quick, and statistically compiled programming language that aids in creating straightforward, dependable, and simultaneous web apps.
• Node.js is an open-source, cross-platform runtime environment to run network and server-side apps with a rich library of JS for fast and quality development. It is event-driven, asynchronous, and runs on a single thread while being highly scalable.
• .NET is a software development framework for desktop and web apps. .NET offers a robust yet straightforward caching system that uplifts speed and performance. Automatic monitoring in ASP.NET is an added advantage.

After the web application architecture and its components, You must be curious about the types of web apps you can build using custom web application development. Well! Here we are on types of web apps for custom web applications.

Types of Web Apps for Custom Web Applications

We have listed the top 9 web application development types and their usage for suitable industries. Here our purpose is to give business owners like you a look at the most commonly used applications for custom web software development.

Static Web App:

The user and server do not communicate in a static web app. Without requesting any information from the server side, it displays the content directly in the end user’s browser. Simple HTML, CSS, and JavaScript are used to create static web apps which display pertinent content. GIFs, movies, and animations occasionally draw in and keep site visitors. Static web applications are relatively straightforward and manageable.

Static web applications include, for instance, a corporation website or a person’s portfolio website.

Dynamic Web App:

A dynamic web application responds to user queries in real time and communicates with the client. To engage the visitor, it has a variety of interactive features. On a technical level, dynamic web apps are significantly more involved and complex. Dynamic web apps can be created using various computer languages, but the most popular ones are PHP and ASP.NET.

Facebook is an excellent illustration of a dynamic online application. It allows for simple login and flawless communication between friends.

Single Page Apps:

Single Page Application, also known as SPA, is a dynamic app that allows users to communicate freely and quickly within a browser. Customer requests and reactions occur more efficiently and rapidly than in typical web applications since SPA conducts logic on the web browser rather than on the server. The SPAs are simple to build, debug, and deploy.

The headers and sidebars, for instance, are preserved when you visit your mailbox in the email app. Single web apps and agility benefit the majority of social networking sites, email services, and online video/audio players quickly. Single-page applications are typically used by Google Mail, Paypal, Netflix, Twitter, and other service providers.

E-commerce

Refers to every eCommerce web app that promotes purchasing or selling something online, such as a store or shop. This web app requires a few essential capabilities, such as transaction integration, online payment integration, an efficient operational panel for administrators, and a user-specific storage area. Technology platforms, including online payment gateways, inventory control systems, mobile commerce, logistics management, delivery route management software, and the internet market, are the focus of eCommerce apps.

Amazon, eBay, Walmart, Swiggy, Zomato, and other well-known e-commerce sites are just a few examples to list.

CMS:

Without technical expertise in programming or markup languages, people can develop, monitor, and alter content on a website using content management system (CMS) software. CMS is widely used in media outlets, corporate, personal, and corporate blogs. The most popular content management platforms are:

1. WordPress:
WordPress is the most well-liked and dependable option for creating a website among amateurs and experts. Without the help of any technical support, you can create unique and user-friendly websites using a plethora of plugins, themes, and online tutorials. However, if you’re looking for a more customized approach, you can hire WordPress developers to help bring your vision to life with professional expertise.

2. Joomla:
Next to WordPress is an open-source content management system called Joomla. Users may easily create, manage, and alter content for websites and blogs because of its user-friendly interface.

3. Drupal:
This open-source CMS is free and has a flexible user interface for creating online communities. Personal blogs, online news sites, media, corporate blogs, professional blogs, etc. are a few uses for it.

Multipage:

Multiple pages make up multipage apps, or MPAs, which reload each page from the server anytime a user switches to a separate page. Different languages, including HTML, CSS, JavaScript, AJAX, jQuery, etc., are used to create MPAs. These apps are valuable since they can be scaled up without page constraints and offer extensive information about the goods or services of the firm.

Catalogs, web portals, commercial web apps, and online shops are just a few examples of MPAs.

Progressive Web App:

The most well-liked and advanced web applications resembling mobile applications are called Progressive Web Applications (PWA). They are also referred to as cross-platform web apps. They provide a native mobile application experience using the most recent browser APIs and progressive enhancement techniques. PWA’s main objective is to increase web apps’ speed and adaptability in the face of sluggish internet connections.

Progressive web applications include those from MakeMyTrip, Forbes, OLX, and Starbucks, to name a few.

Portal Web App:

Apps that permit verified and approved user access to a company’s data repository are portal web apps. Businesses and corporations that allow users to create personal profiles and include numerous details like chats, emails, and forums to submit content will benefit most from portals. The gateway is only accessible to members. The service provider records a user’s website behavior each time they log in to the portal. There are many distinct kinds of online portals, which are frequently connected to diverse sectors.

Examples of portal web apps include student portals, education portals, banking portals, employee portals, patient portals, etc.

Animated Web Applications:

Some companies utilize animated web applications to draw customers’ attention to crucial details. GIFs are a brilliant example of one type that may not be interactive, whereas another type may be dynamic and vary based on how the user engages.

To ensure that users continue to use the app and that both the user’s and company’s data is safe and protected from future data breaches and cyber-attacks, you must troubleshoot and fix bugs in the app as soon as they are discovered.

? Process for Managing Defects

A defect management process is a systematic approach that bespoke web app development teams will use to try to find and resolve defects in web apps. The steps of the defect management procedure are as follows:

• Identification of the Error
• Classification of the flaw
• Developers Correct the Error
• Testing the Correction
• Repair of the Error
• Report of the Error at Project’s End

? Keeping Uptime & Security Issues at Bay

Collaborating with the firm that created the custom web app and utilizing their software testing & QA services is one of the best ways to prevent downtime and security concerns when bugs occur. Since the team created the software, they will be able to find faults more quickly and with less difficulty than a different organization that would need to familiarize itself with the application’s design and code.
