What is a web application?

It is software that runs on a web server designed to be accessed via a web browser. From the tech point of view, a web app is a combination of server-side script and client-side script. The user (client) gets services through a third-party off-site server. We use web apps every day. Common examples are Google apps, Amazon, Facebook, LinkedIn, and YouTube.

What is the difference between web applications and websites?

There are many differences, so now we will mention several most important ones. A website lets users access content that they can see and read. A web application allows you not only to read the page content but also to interact with the page, and manipulate the data. Web applications require authentication and are usually integrated with other software for user convenience. While the functioning of the website is quite simple, web apps are pretty complex. Integration with a web app can be also complex, while it is a lot easier for websites. Browser capabilities are deeply involved in both the web app and website performance.

How much does it cost to develop a web app?

You can get a precise estimation after contacting our experts, because the cost of the web app depends on many factors, such as the development platform (PWA, SaaS), app category and industry, number of users, need for API connection, the complexity of features, and more.

How long does it take to build a web application?

Time estimation depends on the solution complexity. Usually, a small app can take about 2 to 3 weeks to develop. A web app with medium complexity will take up to 6 weeks, while sophisticated development projects can last for about 3 months. You can get a precise estimation by contacting our experts.

What is a Progressive Web App?

The progressive web app is an app the functionality of which is in-between regular web pages and a mobile app. PWAs provide a native-like mobile experience and at the same time can be located on the search engines and accessed via a browser. PWAs offer a faster loading time and offline availability, seamless navigation, and a more engaging experience than other web apps.

Do you provide maintenance and support after developing a web app?

Yes, we provide ongoing technical support, including proactive monitoring and enhancement suggestions. We can also sign a detailed SLA specifying the time for solving critical issues.
