What Is The Difference Between Front-End And Back-End?

Front-End | 27th November 2017

Front-End – In front of what?

Front-end is generally regarded as the visible part of a website, even though it is actually more than that. The front-end developers outline, structure and organize websites and applications based on code, i.e., languages such as HTML, JavaScript, DOM, among others.

Web designers are the ones entrusted with the mission of developing front-end. They can be the ones who develop the whole visual concept, or can work as an interface designer. In this case, the interface designer is the one who conceives the visual traits of interface and, then, the web designer programs them to be interactive and adapted to web supports.

The front-end brings together several fields of knowledge such as aesthetics, UX design, accessibility, among others. This is an array of fields that allows one to see beyond the code, transforming the programming into the visual side of websites with which we are acquainted.

Front-End Development

Back-end - Behind the scenes

If the front-end is typically defined as the visible part of websites and applications, the back-end is defined as the part that remains invisible to the user, and that cannot be controlled by them. In other words, these are the parts of programming that are essential for the functioning of platforms, but they remain “concealed”.

The back-end developers create, and maintain, the components that are accessed by users, in an indirect way, using the front-end. They create the computational logic for the website or the application, based on programming languages such as C++, C#, Java, etc.

Briefly put, the main function of a back-end developer is to ensure that the information and services requested by the front-end are carried out. They are the ones accountable for maintaining the system as a whole, based on process integration. 

Back-End Development

Developing satisfied users

The front-end and back-end are vital for a proper functioning of websites and applications. This is the only way through which one can create the best experience possible for the user, in order for them to make the most out of the platform. We have gathered some key points that you should consider when developing these areas.


It should be appealing

When a user lands on a website, they assess in a matter of seconds whether they will continue there or not. Therefore aesthetics must be taken into consideration in order to engage the customer, but also to convey the values of the brand. If the layout/content of a website is unattractive, 38% of people give up the website (Source: Adobe).

User Experience (UX)

On a website it is very important that one is able to find what he is looking for rather quickly. UX allows streamlining interfaces, with a straightforward design. Therefore, those who visitors enjoy easy navigation, an efficient usability, focused on satisfaction. UX avoids user errors and deviations and builds user-friendly platforms, focusing on the best experience possible. Don't forget, 88% of users will not come back if they have a poor experience (Source: Econsultancy)

When someone is on a website, or in an application, they want to carry out tasks quickly, without wasting time with needless things. That is why these platforms should go “straight to the point” if they want to be successful. This implies short texts, the least amount of menus, as statistics show that it takes only 10 seconds to create a good impression before the user (Source: BlueCorona)

A website must be conceived for any sort of eventuality. If the company grow in size, or have an abnormal peak of web trafficking, the platform must be able to respond and operate, in order to satisfy the user’s needs. The back-end developer should conceive a scalable website, considering all the variables that such task implies (e.g.: capable servers, proper RAM, storage capacity for information, etc.), as 53% of the visitors who land on the website using a phone will give up if it takes longer than 3 seconds to load (Source: Nova Solutions).


Each platform should make an efforts to create the level of security that fits the profile of its information. In other words, the security of an informational website is not the same of a website that deals with personal information of users (e.g.: phone numbers, credit card numbers, addresses, among others). The back-end should take into account these points in order to establish secure platforms and trustworthiness, since 85% of virtual buyers avoid unsafe websites (Source: GlobalSign)

Web services 

Nowadays, websites don’t communicate with humans only, they communicate with other platforms to improve customer service and company management. For instance, web services allow, after a purchase is made, the website to communicate with a bank in order to validate a credit card and, if everything goes according to plan, it communicates with the company’s server to deduct the product, show profit, send an e-mail to those who need to know about the purchase, etc.

Example of a responsive, quick-loading and secure app, that Hi INTERACTIVE helped to develop.

Front-end and back-end: an unbeatable duo

A website, or an application, is more complex than it appears to be. That’s exactly the secret: to hide the complexity of the process, providing a straightforward and positive experience to the user. But the return of a good back-end and front-end development is reflected in several areas:

Maintenance costs are cut down

By having a good back-end structure and a good front-end design, the platform’s maintenance will be lower, because it takes into consideration your long-term needs;

A greater disclosure

A happy consumer is a consumer who likes to share their experience and talks about it within their physical and/or virtual inner circle friends. Your brand will then reach higher grounds based on reliable advertising: personal experience;

Higher return

When a user carries out an action online, where everything goes smoothly, the likelihood of a return is quite significant. This is reflected in a higher return for your company, since for instance, a positive buying experience prompts more purchases.

Straightforward and positive experience to the user

These are some of the reasons that you should take into account, however there are much more that prove the benefit of having a good front-end and back-end. Even though these two fields are seldom mentioned by customers, here at Hi INTERACTIVE we are happy to address any questions you may have, so that you will be able to maximize the potential of your digital platform. Take advantage of all the digital tools, leveraging your company in the web realm.
