Front-End vs. Back-End Developer: What Is the Difference?

Last Updated 12/11/2023

Maybe you’ve just started to explore programming, or you’re already on your way to becoming a web developer. Wherever you’re at on your journey, it’s important to choose the right mix of tools, languages, and specialties that will match your career and personal objectives.

Some web developers decide to specialize in a given programming language (JavaScript, Python, Swift), while others cultivate knowledge in a particular area of web development, such as mobile devices or databases. The most common distinction for web developers is the choice between front-end and back-end, and as you progress in your studies, you’ll undoubtedly encounter these terms more and more.

So, what’s the difference between front-end and back-end web development, and what can you expect from each area in terms of skill set and daily work?

What Is Front-End Development?

Front-end development refers to crafting the user experience and user interface that site visitors interact with. For this reason, the front-end is often called “client-side” because it involves everything that takes place on the client’s computer.

Front-end developers are responsible for customizing a website’s look, feel, and behavior. The user interface includes everything from font sizes and colors to dropdown menus and forms. An excellent front-end experience is essential to attract and retain users.

Because front-end development focuses so much on a website’s appearance and aesthetics, it’s often confused with web design. Although there’s often a fair bit of overlap in skill sets and responsibilities, the divide between designers and developers can usually be summed up as modeling versus implementation.

In the course of their job, web designers may engage in user research, build wireframes and mock-ups, create graphics and logos, and select fonts and color schemes. They dictate how the website will look and feel. Meanwhile, front-end web developers focus primarily on the technical details of how to bring web applications to life.

What Does a Front-End Developer Do?

Here’s a list of typical tasks a front-end developer handles:

• Building pages using HTML

• Styling elements using CSS

• Connecting application programming interfaces (APIs) to send and receive information

• Adding images and buttons to web pages

• Optimizing web pages for Search Engine Optimization (SEO)

• Designing a unified UI that customers can easily interact with

• Observing and noting how users interact with the UI to continually improve the overall experience

Front-End Developer Career Outcomes

Front-end developers can benefit from many well-paying career opportunities across various industries. As of October 2024, the national average salary for front-end developers is $86,138 (Glassdoor), with plenty of room for advancement. While each individual’s career path is unique, many entry-level developers will start in junior positions and work up to senior-level and C-suite roles.

Additionally, front-end developers can pursue further specializations in areas based on their interests, such as UI/UX or accessibility.

What Is Back-End Development?

Back-end development, on the other hand, is about defining a website’s internal logic. While the front-end of a website is called “client-side,” the back-end is referred to as “server-side” because it runs on the website’s server and not on the user’s computer.

Every website’s back-end consists of three parts: the server, the database, and the application. Back-end developers write code that enables these three components to interact and work together to perform functions and deliver information to the end user.

For example, when you place an order via an online marketplace like Amazon or Etsy, the back-end software creates a new entry in that website’s database that contains information about your order, such as the item, price, and shipping address. When you want to retrieve the order or change a piece of information, the software pulls your specific entry from the database and sends the data to the front end of the site, where you can edit it.

What Does a Back-End Developer Do?

Here’s a list of everyday responsibilities a front-end developer handles:

• Planning and shaping the application’s overall architecture

• Creating APIs to handle data, serving the information to front-end and other appropriate applications

• Handling, adjusting, and using the data gathered from an API

• Scaling the application to handle significant data influxes

• Creating, structuring, and maintaining all relevant databases

• Handling security functions such as user authentication

Back-End Developer Career Outcomes

Back-end developers are crucial in developing many technologies, including websites, mobile applications, and video games. Based on Glassdoor data from October 2024, back-end developers earn, on average, $89,820 per year with many career paths. Like their front-end counterparts, back-end developers can also specialize in specific focus areas, such as:

• Cloud Computing

• Cybersecurity

• Performance

• Data

• Machine Learning

The Difference Between Front-End and Back-End Development

A good example of the distinction between a website’s front-end and back-end is Google Maps. Let’s say you pull up Google Maps to find the fastest way to get to your friend’s house. You enter your starting point and destination into the website’s front-end, which then sends your search query to the back-end, which is running somewhere on Google’s servers. The website’s back-end calculates, for multiple modes of transportation, the most efficient routes between the two places you entered and sends these routes back to your computer. The front-end takes this routing information and displays it to you on a map of your current location.

Back-end developers for Google Maps are responsible for building smart, efficient pathfinding algorithms that get you to where you need to go in the shortest amount of time. Front-end developers are responsible for displaying that information in a way that’s attractive and easy for you to understand.

Once you grasp the difference between the front-end and the back-end, you can start to see any large website in terms of this division. For example, Facebook’s back-end includes software applications that determine how to order your friends’ posts in your timeline and which users to recommend as friends, while the Facebook front-end receives this information and displays it to you in a pleasant, user-friendly interface.

The front-end and back-end are usually entirely separate from each other. Facebook is constantly changing the back-end algorithms it uses to order content, but it’s rare for developers to alter the platform’s front-end to reflect these changes.

Front-End vs. Back-End: The Skills Required

Now that you know the difference between the front-end and back-end of a website, which programming languages do you think are best to learn for each field?

Front-End Skills

HTML, CSS, and JavaScript are the primary front-end languages. Sign up for Fullstack Academy’s free online Intro to Coding course to start learning.

• HTML: A markup language used to describe the structure and content of a web page. Tags are the basic unit of HTML: They are written with angle brackets <> and provide semantic information about the text that they surround. One common usage is to denote a page’s title and headings. HTML itself is invisible to the end user, but its commands are not.

• CSS: A style sheet language that works in conjunction with HTML to describe the design and appearance of a web page. For example, a CSS file may define that any text surrounded by the HTML <a> tag, which is used for hyperlinks, appears green and bold. Neither the CSS file nor the HTML, as mentioned, can be seen by the user; all they will see is a bold, green link.

• JavaScript: A programming language used to create interactivity and dynamic content on a web page—and the focus of the curriculum taught at Fullstack Academy. JavaScript can do everything from displaying the current date and time to validating a user’s form input to adding animations. As with all programming languages, JavaScript is not visible to the end user, but its effects on the objects it acts on—forms, images, etc.—are.

In tandem with these three pillars of front-end development, many programmers will employ a variety of frameworks and libraries to make it easier to write and organize their front-end code. These add-ons to HTML, CSS, and JavaScript aim to make development faster and more structured.

Some of the most popular front-end frameworks and libraries include Bootstrap, jQuery, AngularJS, and React (for JavaScript), plus Sass and LESS (for CSS). Front-end devs must also use mobile-first or responsive design to ensure web pages render well across devices.

Back-End Skills

The roadmap for back-end development is a little less clear-cut. Software that runs on the back-end can be written in hundreds of different programming languages, so back-end developers usually narrow things down to a handful of languages that are best suited for their needs. JavaScript, though initially a front-end language, is increasingly being used on the back-end, thanks to the popular server framework Node.js. Other common back-end languages include Scala, Python, Ruby, and Go.

Like front-end developers, back-end developers, too, employ frameworks and libraries to take care of low-level technical details, so the developers themselves can focus on the higher-level tasks at hand. (Sort of like using the “SUM” function in Excel to get a departmental budget done more quickly instead of adding everything up yourself.) Back-end frameworks and libraries include Rails for the Ruby programming language and Django for Python.

Nearly every website that allows users to make requests will have a database on the back-end. In addition to programming language know-how, back-end developers should have some experience with database technologies like Oracle, Microsoft SQL Server, and MySQL. This knowledge is used to write business logic, or a set of rules, into the back-end code. Developers use these rules to dictate how to create database models, how to write to the database, and how to query it for relevant information.

Why It’s Important to Know Both Front-End and Back-End Skills

Even though you’ll probably choose between front-end or back-end in your career, there are many benefits to having both skill sets. In the Fullstack Academy full-time and part-time immersive programs, students begin to master HTML5, advanced CSS, and modern technologies like React on the front-end and Node.js and APIs on the back-end. Because Fullstack Academy focuses on one programming language—JavaScript—as opposed to focusing on multiple, its programs uniquely prepare students to work seamlessly in both realms.

By learning both front-end and back-end skills, students are better prepared for the workforce and can cultivate a successful career as software developers by adding more value to their teams and employers.

Which Type of Development is Right For You?

So, you can become a front-end, back-end, or full-stack developer. But which is your best option? Like many other life choices, it depends on the individual.

Are you a creative type who enjoys artistic processes and graphic design? If so, then you should consider front-end development.

On the other hand, if your passion is problem-solving, logic, and troubleshooting, then back-end development is where you should be.

But finally, if you’re a solid blend of creativity and logic, pursue full-stack development.

Up Next: Choosing a Program or Bootcamp

Demand is high for software developers, and there’s no shortage of coding bootcamps to teach you front-end, back-end, or full-stack development. When considering which coding bootcamp to choose, the most important criteria should be whether the program will prepare you for the job you see yourself in.

For example, coding bootcamps focusing exclusively on the Swift programming language will prepare you to develop iOS apps but not build websites. Bootcamps that teach you a wide range of skills might give you much flexibility, but you might not develop enough expertise in any language to find a job. You’ll have to choose between versatility and specialization to land a position in your chosen field.
