Frequently Asked Questions

There will always be many questions when choosing a partner and software solution. Here we’ve listed some of the most frequently asked questions at the agency about web application development.

Web apps, or web applications, are software programs that are stored on remote servers and delivered over the Internet through a browser interface. Unlike traditional desktop applications, which need to be installed on the user’s computer, web apps can be accessed through the web browser, requiring no installation on the user’s device.

Web apps are built using web technologies such as HTML, CSS, and JavaScript and can be accessed using various web browsers like Google Chrome, Mozilla Firefox, Safari, etc. They run on a web server, and the user interacts with them via a web client.

Progressive Web Apps (PWAs) are a type of web application that use modern web technologies to provide a user experience that is similar to a traditional or native mobile app. PWAs can be thought of as a hybrid between regular web pages (or websites) and a mobile application.

They are designed to work on any platform that uses a standards-compliant browser, including both desktop and mobile devices.

Here are some key features of PWAs:

  1. Progressive: They work for every user, regardless of browser choice, because they’re built with progressive enhancement as a core tenet.
  2. Responsive: They fit any form factor, desktop, mobile, tablet, or whatever is next.
  3. Connectivity Independent: Enhanced with service workers to work offline or on low-quality networks.
  4. App-Like: They mimic the interaction and navigation of native apps.
  5. Fresh: Always up-to-date thanks to the service worker update process.
  6. Safe: Served via HTTPS to prevent snooping and ensure content hasn’t been tampered with.
  7. Discoverable: They are identifiable as applications thanks to W3C manifests and service worker registration scope allowing search engines to find them.
  8. Re-engageable: They make re-engagement easy through features like push notifications.
  9. Installable: Allow users to “keep” apps they find most useful on their home screen without the hassle of an app store.
  10. Linkable: Easily shared via a URL and do not require complex installation.

Twitter, Pinterest, and Starbucks, among others, have progressive web apps that offer offline functionality and almost identical features to their native apps.

No at all. Whilst you can outsource your web development to us, we don’t outsource any of our development work. As web app developers with offices in London and Surrey, we’re a 100% UK based web development company.

What is web development?

Web development is the process of building and maintaining websites. It encompasses a wide range of activities, from creating simple, static web pages to developing complex, dynamic web applications. It includes both front-end (client-side) and back-end (server-side) development.

What is web app development?

Web app development is a specialized area within web development focused on creating application-like programs that run on a web server and are accessed through a web browser. These are typically more complex and interactive than standard websites.

What are the key differences in skills required for web development and web app development?

While both fields require knowledge of HTML, CSS, and JavaScript, web app development often demands a deeper understanding of advanced web technologies and frameworks (like React, Angular, Vue for front-end; Node.js, Laravel or .NET for back-end), as well as expertise in areas like state management and dynamic content.

Can a web development company build a web app?

Yes, a web developer or company can build a web app, especially if they have the necessary skills in advanced web technologies and frameworks. However, building complex web apps requires specialised knowledge in web app development.

Examples of web applications include social media platforms (e.g., Facebook, Twitter, TikTok), email services (e.g., Gmail, Outlook), e-commerce sites (e.g., Amazon, eBay), online banking platforms, CRMs such as HubSpot, productivity tools such as, Asana, even popular everyday sites such as AirBnb, Uber and Lyft have several web apps as part of their platform.

Web applications typically consist of a client-side component (i.e., the user interface) and a server-side component (i.e., the back-end logic). The client-side component is executed in the user’s web browser, while the server-side component is executed on a web server.

What technologies are used to build web applications? Web applications can be built using a variety of technologies, including HTML, CSS, JavaScript, and various web frameworks such as Angular, React, and Vue on the front-end, and server-side languages such as PHP, Python, and Ruby on Rails on the back-end.

Web applications are highly accessible and can be accessed from any device with an internet connection. They can also be easily updated and maintained without requiring users to download or install new software.

While a website is a collection of web pages that provide information about a particular topic or organisation, a web application is a software program that allows users to perform specific tasks or functions. Web applications typically have more complex functionality than websites and require more sophisticated programming and design.

Responsive design is a design approach that ensures that web applications are optimised for different screen sizes and devices. It is important for web applications because it ensures that users can access and use the application on any device, from smartphones to desktop computers.
