Custom Web applications are digital products developed for a particular client from scratch. Alternatively, they may not be built from scratch but customized at a request – for instance, this often happens to learning management systems.

Custom web application development is usually available with any type of desired web app. WeSoftYou team’s expertise allows for building custom web portals, tailored web applications, cloud-based solutions, IoT and API solutions, as well as any other custom solution at the intersection of mentioned products. Get in touch with us to discuss your idea.

The entire process of custom web software development consists of front- and back-end development.

Front-end includes everything users see on their screens. It receives data from the server, processes them, and displays it to the user. Besides, this part of the application provides the ability to interact with the interface and handle user actions.

Back-end is the server side of your app. This part of the application stores all necessary information and then structures this data at the request of the client application.

Provided that back-end received data differs in its nature, just like the app’s original purpose does, selecting a technology stack for web application development does not have a special formula. Since every project is different and has specific needs, the response will vary depending on the project. The same project can utilize a variety of databases and programming languages.

The best platforms for custom web app development include WordPress, AngularJS, ASP.NET, Symfony, Node.js, and React.js.

WordPress is the most popular website-building platform, a classic choice for blogs and text content websites as it is good with search engine indexing.

Angular JS is excellent for user-review applications, social apps, mobile commerce, travel apps, weather apps, and video streaming apps. It’s used by businesses like Microsoft, Upwork, Netflix, Paypal, Google, and other worldwide-recognized unicorns. is ideal for developing desktop and mobile applications. It provides dynamic and scalable web apps.

Symfony is a framework for PHP web development. It helps create complicated, high-performance online applications. A few developers may easily manage a Symfony project.

When creating a website that is really efficient, Node.js is a smart choice. It is a JavaScript-based platform with a lot of capabilities. You may create online apps like single-page programs, video streaming websites, and many more. Developers are using practical frameworks to meet their web development demands as technology evolves.

React.js allows you to create high-performance and SEO-friendly web apps. Working on a single-page application makes React unquestionably worthwhile. With React.js, you can create web apps that are user-friendly, responsive, and lightning-fast.
