You can learn to code for free. Pick one language and one structured free course, write code every day, and build small projects as soon as you can. For most beginners that means freeCodeCamp or The Odin Project for web development, or Harvard’s CS50 for general computer science, plus a place to practice problems. The list below covers resources that exist as of October 2026 and says which parts are free and which are not.
First choose a direction
“Learning to code” is not one thing. Your first language depends on what you want to build:
- Websites and web apps: HTML, CSS and JavaScript.
- Data, scripting, automation or interviews: Python is a common starting point.
- Not sure: pick Python or JavaScript. Both have plenty of free material, and what you learn about variables, loops, functions and debugging carries over to any other language.
Do not collect five courses in five languages. Finish one.
Free structured courses
A structured course tells you what to learn next, which is the hardest part for a beginner.
freeCodeCamp
A nonprofit (a US 501(c)(3) charity) that offers courses, projects and certifications at no cost. Its own site says each certification takes roughly 300 hours at your own pace. You write code in the browser, so there is nothing to install at the start. It is open source and not a bootcamp, and it has no human instructor, so you rely on the forum when you get stuck. Good for: web development from zero. Cost: free.
The Odin Project
An open source, volunteer-maintained curriculum for becoming a full stack web developer, started in 2013. It sends you to articles and projects and has you set up a real development environment early, which is harder at first but closer to real work. Help is mostly through its Discord community. Good for: people who want a project-heavy path to web development. Cost: free.
CS50x (Harvard)
Harvard’s introduction to computer science. It is free to take: you work through eleven weeks of material and a final project. It starts with C, then moves to Python, SQL, and HTML, CSS and JavaScript. It teaches how computers and algorithms work, not just syntax, and it moves fast. To submit problem sets for feedback you need an edX account. Certificates and Harvard credit are separate paid options. Good for: people who want fundamentals and can handle a steep start. Cost: free to take; certificates cost extra.
MDN Learn web development
Mozilla’s free tutorials on HTML, CSS, JavaScript, accessibility, version control and more, with “test your skills” exercises and challenges. It aims to take you from beginner to comfortable with front-end development. It is more of a reference-quality textbook than a game. Good for: a second source alongside a course, or a quiet read-and-try path. Cost: free.
Kaggle Learn
Short, free, browser-based courses on Python, pandas, data visualization and machine learning, run in Kaggle Notebooks. Good for: beginners aiming at data science. Cost: free.
Free books and documentation
- Eloquent JavaScript by Marijn Haverbeke: the 4th edition (2024) can be read free online, and a paperback is for sale. The first half covers fundamentals; the second applies them in the browser and Node.js. It is dense, so treat it as a book to read alongside exercises.
- The official Python tutorial at docs.python.org: good and free, but it says it is written for programmers new to Python, not for people new to programming. If you have never coded, start with a beginner course first and use the tutorial later.
- MDN Web Docs is the reference you will use for years for HTML, CSS and JavaScript.
Interactive platforms with free tiers
Free tiers change, so check each site before you plan around them.
- Codecademy: interactive lessons in the browser. As of October 2026 its pricing page lists a free Basic plan with limited course access, while skill paths, certificates and portfolio projects need a paid plan. Good for a first taste of a language.
- Sololearn: its site describes it as a free, mobile-first platform for learning to code. Handy for short sessions on a phone, but you still need to write real programs on a computer.
- AlgoCademy: lessons that move from the basics to algorithms and interview problems, with step-by-step hints. It is a better fit once you know a bit of syntax and want to learn how to solve problems. You can start with printing to the console and variables in the Python course, or browse the app.
Practice problems once you know the basics
After a few weeks of syntax you need to solve problems on your own. Codewars gives you small challenges called kata, ranked by difficulty, with other people’s solutions to compare against once you finish. HackerRank, widely used by companies for hiring tests, also has practice challenges; check its pricing page for what is free. Some beginners find both hard at first. If so, go back to a course for a week and return later.
Resources from the old version of this list that no longer work
- Grasshopper (Google’s JavaScript app) was shut down on June 15, 2023.
- Lambda School became Bloom Institute of Technology (BloomTech) and is no longer operating as a bootcamp. Do not plan around it.
What about bootcamps, Coursera, edX and Udemy?
These are paid or partly paid options and not a free path. A few general points that stay true:
- Coursera and edX host university and company courses. Some courses can be viewed for free without a certificate or graded work, but this varies per course and changes over time. Check the course page.
- Udemy courses are paid individually, and quality depends on the instructor. Read reviews and preview lessons.
- Bootcamps are intensive and expensive, and outcomes vary widely. Before paying, ask for audited placement figures, read the refund terms, and read how any financing or income-share agreement works. You do not need one to start.
A simple plan for the first 90 days
- Weeks 1 to 4: one beginner course (freeCodeCamp’s first certification, the start of The Odin Project, CS50x, or a Python basics course). Code every day, even 30 minutes.
- Weeks 5 to 8: keep going, and after each topic write a tiny program yourself without copying: a number guessing game, a to-do list, a unit converter, a page with a form.
- Weeks 9 to 12: build one project that you care about, push it to GitHub, and start solving easy practice problems a few times a week.
Watching videos can feel like progress while teaching you little. The post on why watching tutorials is not learning explains why you should close the video and type the code yourself. For a realistic time estimate, see how long it takes to learn programming from scratch.
Common mistakes
- Switching courses when it gets hard. The hard part is usually the thing you are supposed to learn.
- Copying code you do not understand. After each lesson, redo the exercise from a blank file.
- Waiting to feel ready to build. Small, ugly projects teach more than another tutorial.
- Learning alone with no feedback. Use a forum, Discord, or a study partner, and read error messages before asking.
- Treating AI tools as the teacher. They can explain an error, but if they write every line for you, you will not learn to debug. Try first, then ask.
