Learn to Code for Free in 2023

You do not need to be a student at a college or university to learn to code and advance your technology career. The best remote coding bootcamps and massive open online course (MOOC) platforms both feature online coding classes with full curricula. Detailed tutorials are also offered by major tech companies like Google, which directly benefit from boosting your coding skills. 

Given the incentives, tech industry experts are often the ones designing and running free workshops on the most popular programming languages and the fundamental concepts of coding. In this article, we will survey courses, interactive tutorials, and other resources that cover how to code, for beginners and intermediate learners alike. 

Why Learn Coding?

You should learn to code because it will open you up to a slew of employment opportunities. You can become a software engineer, web developer, mobile app developer, or computer programmer. The Bureau of Labor Statistics (BLS) projects that jobs for software developers will increase by 22 percent between 2019 and 2029.

Learning how to code and acquiring Python, JavaScript, SQL, C#, or Java skills will also increase your earning potential. The PayScale estimates below show just how much the average tech worker with skills in one of these programming languages can earn in a year.

Top Programming Languages for Beginners

Recent advancements in the science and art of computer programming have made it much easier for coding newbies to write simple, fast, and high-quality code. The three highly functional programming languages listed below were developed with these criteria in mind. They are great options for beginners, students, or anyone trying to advance their careers. 


Since Python was designed for use in a variety of application domains, it is an outstanding baseline for any student who wants to eventually code across all platforms. It is also a compelling option for beginners because it allows you to write clear and logical code, regardless of project scale. Python tutorials are readable and easy to follow. 


Kotlin is a general-purpose programming language. Like Python, it can be used across multiple platforms. Kotlin was designed to be easy for beginners to pick up and use as a base for their coding development. Aspiring mobile app developers should learn Kotlin because it is the preferred language for Android. The association with Google is a plus. 


PHP can also be used across multiple platforms and for various applications. Those who know how to use PHP often focus on web development, but it can also be used to create graphical user interfaces and to develop robotic controls for the management of drone flights. PHP is the subject of many online coding classes. Learning the core concepts of this language will significantly help you in your career.

How to Learn to Code for Free

To find the best free coding tools, you first need to decide what you want to do with your programming skills. For most career paths, the most affordable learning options come straight from the tech giants. For example, Android, Apple, Microsoft, and Oracle all have basic free courses and comprehensive curricula on their online training platforms. There are even free coding bootcamps you can enroll in to pick up the fundamentals of coding.   

By using these resources to your advantage, you can learn to code for free. Below is a learning path you can follow, moving from simple to more complex.   

Step 1: Learn Kotlin for Android 

You should start with Kotlin because it is a modern programming language and is known for its accessibility. The only prerequisite is a desire to work with Android. Once you have learned how to code a basic layout using Kotlin, you can create your own Android apps. Best of all, the Google Developers platform offers free Kotlin courses. 

Step 2: Learn to Code with Apple

Apple also has a highly specialized learning platform for developers, which is completely free. After mastering the core concepts of Kotlin, you should be able to learn Swift and Objective-C, the two most relevant languages for Apple users. Both of these iOS coding languages are suitable for complete novices or for anyone just starting out.

Step 3: Learn to Code with Python

Python is suitable for beginners to coding, but it will be even easier if you’ve already learned to code on other platforms. Tech giants like Microsoft will teach you the basics of Python programming for free. From there it’s just a matter of building on that knowledge with an intermediate or advanced online class, which can teach you more complicated tasks.
