Front-end vs. Back-end: What is the difference

Terms like front-end and back-end development may be confusing to someone who is new to the world of coding and software engineering. Let’s clear up some of the ambiguity around some of these technical phrases. We’ll explain the differences between the front-end and back-end.

Today, we’re addressing the following issues and demystifying the distinctions between development styles:

  • What is front-end development? 
  • What is back-end development? 
  • What differences exist between front-end and back-end development

Front-end development

Front-end developers create with the user in mind. Front-end development is a type of computer programming that focuses on the coding and building of website/app parts and functionality that will be visible to the user. It is focused on ensuring that the aesthetic parts of a mobile application are functioning. 

Back-end functionality in mobile apps can sometimes be stored locally rather than on the server. These programs are generally offline, which means they may be downloaded and used without an internet connection. In this case, mobile developers would be responsible for both the front-end and the back-end.

Consider the front-end to be the “client-side” of an application. Assume you’re a front-end developer. This implies that your job is to code and bring the visual parts of a mobile app to life. You’d be more concerned with what a person sees when they visit a website or utilize an app. You’d also want to make sure the user interface (UI) is simple to use and runs properly, and that the user experience (UX) is desirable.

These developers bring the visual concepts created by UX and UI designers to life, ensuring that the website or an app performs properly for the user.

Things front-end developers do:

  • Improving the user experience.
  • Creating mobile applications.
  • Bringing concepts to life with Android studio and Kotlin (for android apps), Xcode and Swift (for iOS apps), HTML, JavaScript, and CSS (for web).
  • Creating and updating the user interface.
  • Using design on mobile apps or websites.
  • Developing technologies to improve site interaction across browsers.
  • Managing the workflow of the software.
  • Following excellent SEO tactics.
  • Bug fixes and usability testing

Back-end development

Back-end development deals with the aspect of the website that visitors do not see. It is what allows a website to be interactive. The back-end of a website is sometimes known as the “server side.” 

Assume you own and operate a social networking platform. You’ll need a convenient location to save all of your users’ information. A database is a type of storage center, and some popular examples are Oracle, SQL Server, and MySQL. A database is managed by a server, which is effectively a remote computer. A back-end developer will assist in the management of this database and the site information stored on it. This guarantees that your social networking website’s front-end features continue to function properly when visitors view posted material and other user profiles.

​​While visitors do not directly contact the back-end of a website, they will interact with things that these developers are working on via a front-end application. Back-end development is concerned with storing and organizing data while also ensuring that the front-end works properly.

Things front-end developers do:

  • Database development, integration, and management
  • Frameworks for developing server-side software on the back-end
  • Technologies used in web servers
  • Integration of Cloud Computing
  • Server-side programming languages
  • System software
  • Development, deployment, and maintenance of content management systems
  • API interoperability
  • Cyber security.
  • Reporting entails the creation of analytics and data.
  • Technologies for backing up and restoring website files and databases

Front and back-end developers use different technologies

A programming language will be used while you code. These languages, like human languages, enable programmers to communicate with their computers using a set of symbols (referred to as code). Simply explained, it’s the same as giving your computer instructions. Front-end developers use programming languages such as XML, Kotlin, and Swift for mobile development, and HTML, CSS, and JavaScript for web development.

  • XML is an acronym for Extensible Markup Language.XML tags define data and are used to store and organize information. XML is utilized in Android to implement UI-related data, and it is a lightweight markup language that does not make the layout heavy.
  • Kotlin is a trendy, contemporary programming language. Kotlin may be used for server-side, client-side web, and Android programming.
  • Swift is an extremely powerful and user-friendly programming language for iOS, iPadOS, macOS, tvOS, and watchOS. Swift code is interactive and enjoyable to write, and the syntax is compact yet expressive.
  • HTML is an acronym for Hyper Text Markup Language. It is the most often used markup language for constructing web pages.
  • CSS is an acronym for Cascading Style Sheets. CSS is used to provide style and flare to a webpage, whereas HTML is used to establish structure. It specifies the colors, fonts, and style of other site content.
  • JavaScript is a programming language that may be used to make a website dynamic and entertaining. For example, you might use it to host a game on your website.

Front-end developers use their own frameworks and libraries. A front-end developer could deal with the following frameworks and libraries:

  • Native Android
  • Native iOS
  • Non-Native mobile frameworks (Swiftic, Native Scripts, React Native, Xamarin, Flutter)
  • AngularJS
  • React.js
  • jQuery
  • Sass

PHP, C++, Java, Ruby, Python, JavaScript, and Node.js are some of the languages used by back-end developers. Here’s some more information about a handful of these languages:

  • PHP is a scripting language used on the server.
  • Java is a well-known platform and computer language.
  • Python is a multi-purpose programming language. It differs from some of the others described here in that it may be used for other types of software development as well as web development.

Back-end frameworks include the following:

  • Express
  • Django
  • Rails
  • Laravel
  • Spring


Front-end development is a branch of programming that focuses on the visual parts of a website or app with which a user would interact (the client side). Meanwhile, back-end development is concerned with the aspect of a website and app that visitors do not see (the server side). They collaborate to develop dynamic websites and apps that allow users to make purchases, use contact forms, and engage in any other interactive activities while perusing a site. Netflix, PayPal, Facebook, Youtube, etc. are all instances of dynamic websites/apps.


Mobile App vs. Website: What is best for your business

As a CEO or business owner, you have probably considered how to attract customers and what strategy to use, such as whether to develop a website or mobile application. There is no definitive answer because the alternative you pick will rely on your business plans, your resources, and any properties you might require.

We would like to share our expertise in this area and highlight the advantages of mobile apps to assist you in making the best decision for your company.

Numbers speak for themselves

In 2020, mobile devices accounted for 68.1% of all website visitors globally, up from 63.3% in 2019. 28.9% of visitors came from desktops, while 3.1% came from tablets.

This shows that the mobile users percentage keeps growing every year and that the future is undoubtedly mobile. On the graph below you can see that the number of mobile online users surpassed desktop users as far as in 2013. and this difference is bigger every year.

The Ideal Situation to Develop a Mobile App

There are many circumstances where creating a mobile application is the best option for addressing particular company objectives:

  1. An application would be a better solution than a website, for example, if you intend to set up features tied to native device capabilities, such as GPS, click-to-call, cameras, scanners, BlueTooth devices, etc.

  2. Another appropriate occasion to pick an application is when you’re developing a platform, like a social network or a content marketplace, that has to maintain all these components functional and dynamic and requires access to multiple sorts of content (such as images, texts, music, and Youtube videos).

  3. Applications are ideal for interactive games like Angry Birds, daily utilities like Evernote, and services that let you train, monitor your progress in real time, and receive reminders on a regular basis (FitBit, Duolingo).

  4. A mobile application is also a viable option for data manipulation. It’s also preferable to use an app for processing complex computations and creating reports, such as in banking and finance. In addition to a full website, a mobile app may be a terrific supplement for banking operations and services. Banks (such as Banca Intesa and Raiffeisen) successfully implement this concept by focusing solely on the most widely used desktop web capabilities that are essential for usage on the go and include them in their applications in a way that makes them simple and convenient to use.

Advantages of choosing an app over a website

  • Convenience. Analysis reveals that the applications are more widely used than comparable websites because they are more practical. Mobile applications are simpler to use, offer better user experiences, and load content more quickly. In addition, applications feature push alerts, unlike web pages. Within an app, communicating updates, unique features, and reminders improves user retention. Additionally, compared to websites, the design of mobile applications more gracefully adapts to various screen sizes.

  • Personalization. Apps for mobile devices are a fantastic solution for services that need frequent use. Users may configure preferences, make personal accounts, and store important information in an application. From a commercial perspective, mobile applications offer superior assistance for audience targeting and subsequently designing marketing campaigns for various user groups.

  • Working offline. The ability to utilize mobile apps offline is an additional significant benefit. Apps can continue to offer access to material and services after being downloaded and installed on a mobile device, even if there is no internet connection.
