Quick answer
Follow one structured course end to end and use the rest as references. Pick freeCodeCamp if you like learning in the browser with certificates, or The Odin Project if you want to build real projects on your own machine. Keep MDN and JavaScript.info open for look-ups, use react.dev when you reach React, and roadmap.sh to see what comes next.
Free web development sites compared

The 7 best free sites, one by one
Listed in a sensible study order, not ranked. You do not need all seven: one course plus two references is plenty.
MDN Web Docs (Learn web development)
Best reference · also a free course- Price
- Free
- Format
- Written tutorials, challenges
- Run by
- Mozilla and contributors
MDN is where developers check how HTML, CSS and JavaScript actually behave. Its Learn web development section is a structured front-end course: getting started, HTML, CSS styling and layout (Flexbox, Grid, responsive design), JavaScript, frameworks, accessibility and version control, with challenges at the end of modules.
Use it for: accurate answers. When a random blog and MDN disagree, trust MDN.
freeCodeCamp
Best for learning by doing- Price
- Free (non-profit)
- Format
- Interactive lessons, projects
- Certificate
- Yes, free
A non-profit with an interactive curriculum: you read a short step, write code in the browser and the tests tell you if it is right. Each certification ends with projects you build yourself. It also publishes a huge library of free articles and full-length video courses.
Watch out for: passing browser tests is not the same as building on your own machine. After a section, rebuild one project from scratch in VS Code.
The Odin Project
Best project-based full-stack path- Price
- Free, open source
- Paths
- Foundations, then Full Stack JavaScript or Ruby on Rails
- Community
- Discord
A free, open-source curriculum that teaches you to work like a developer from day one: you set up a real environment, use Git and the command line, and build projects on your own computer instead of in the browser. It points you to the best existing articles and docs and tells you what to build with them.
Who it suits: self-motivated learners who want a portfolio. Watch out for: it is reading-heavy and expects you to search for answers yourself, which is exactly the skill a job needs.
JavaScript.info (The Modern JavaScript Tutorial)
Best for really understanding JavaScript- Price
- Free to read online
- Format
- Written chapters with tasks
- Covers
- The language, browser, and extra topics
A complete JavaScript tutorial, from variables to closures, promises, async/await, classes and modules, then the browser (DOM, events, forms). Each chapter ends with small tasks and solutions.
Use it for: the "why" behind JavaScript, and interview preparation. Read a chapter, then do every task without looking at the answer.
CSS-Tricks
Best CSS reference articles- Price
- Free
- Format
- Articles, guides, Almanac
- Must-read
- Flexbox and Grid guides
Years of in-depth articles on CSS and front-end development. Its visual Complete Guide to Flexbox and Complete Guide to CSS Grid are among the most bookmarked pages in web development, and the Almanac explains individual properties and selectors with examples.
Watch out for: it is a library, not a course, and some older articles predate modern CSS. Check the date and confirm on MDN.
react.dev (official React docs)
Best place to learn React- Price
- Free
- Format
- Docs with live, editable examples
- Start with
- Quick Start, then the Tic-Tac-Toe tutorial
The official React documentation, rewritten around modern React (function components and Hooks). The Learn section starts with a Quick Start that covers the concepts you use every day, then a hands-on Tic-Tac-Toe tutorial, then deeper chapters on state, effects and thinking in React.
When to start: once you are comfortable with JavaScript arrays, objects, functions and modules. React on top of shaky JavaScript is the most common beginner trap.
roadmap.sh
Best for knowing what to learn next- Price
- Free to use
- Format
- Interactive roadmaps, guides
- Roadmaps
- Frontend, Backend, Full Stack and many more
Community-made visual roadmaps for front-end, back-end, full-stack and many other roles. Click a topic to see what it is and links to learn it, and tick off topics to track your progress.
Watch out for: the full roadmaps are long and can look scary. You do not need every box to get a first job: follow the main path and skip the "optional" side branches at first.
Our honest pick
Choose one course and finish it: freeCodeCamp if you want guided, in-browser lessons and a certificate, or The Odin Project if you want to build real projects on your own computer. Most people who fail to learn for free do not pick the wrong site; they keep switching sites.
Keep MDN and JavaScript.info as your references, move to react.dev once JavaScript feels comfortable, and check roadmap.sh only when you are wondering what comes next.
A simple free study order
- HTML and CSS basics (2–4 weeks): MDN Learn or freeCodeCamp. Build a personal page and a landing page.
- Layout (1–2 weeks): the CSS-Tricks Flexbox and Grid guides. Make your pages responsive.
- JavaScript (6–10 weeks): JavaScript.info, with The Odin Project or freeCodeCamp projects for practice.
- Git and GitHub: put every project online from now on.
- React: react.dev Learn, then rebuild one earlier project in React.
- What next: use roadmap.sh to choose back-end, full-stack or something else.
Times are rough guides for someone studying about an hour a day; go at your own pace.

Frequently asked questions
Can I really learn web development for free?
Yes. MDN, freeCodeCamp, The Odin Project, JavaScript.info and the official React docs together cover HTML, CSS, JavaScript and React to a job-ready level at no cost. What you cannot get free is someone keeping you on schedule, so pick one course and stick to it.
Which free website is best for learning web development?
For a guided start, freeCodeCamp (interactive lessons and free certifications) or The Odin Project (real projects on your own machine). MDN Web Docs is the best free reference to keep open alongside either one.
Do free web development certificates help you get a job?
A little. A certificate shows you finished a course, but recruiters mainly look at your projects on GitHub and a live portfolio. Treat the certificate as a bonus and spend most of your time building.
