Pull Requests Welcomefirst-timers-only FriendlyOpen Source HelpersSetup Automated's open-source codebase and curriculum is a friendly community where you can learn to code for free. It is run by a donor-supported 501(c)(3) nonprofit to help millions of busy adults transition into tech. Our community has already helped more than 10,000 people get their first developer job.

Our full-stack web development curriculum is completely free and self-paced. We have thousands of interactive coding challenges to help you expand your skills.

Table of Contents

Certifications offers several free developer certifications. Each of these certifications involves building 5 required web app projects, along with hundreds of optional coding challenges to help you prepare for those projects. We estimate that each certification will take a beginner programmer around 300 hours to earn.

Each of these 30 projects in the curriculum has its own agile user stories and automated tests. These help you build up your project incrementally and ensure you've fulfilled all the user stories before you submit it.

You can pull in these test suites through freeCodeCamp's CDN. This means you can build these projects on websites like CodePen and Glitch - or even on your local computer's development environment.

Once you’ve earned a certification, you will always have it. You will always be able to link to it from your LinkedIn or résumé. And when your prospective employers or freelance clients click that link, they’ll see a verified certification specific to you.

The one exception to this is if we discover violations of our Academic Honesty Policy. When we catch people unambiguously plagiarizing (submitting other people's code or projects as their own without citation), we do what all rigorous institutions of learning should do - we revoke their certifications and ban those people.

Here are our six core certifications:

1. Responsive Web Design Certification

Projects: Tribute Page, Survey Form, Product Landing Page, Technical Documentation Page, Personal Portfolio Webpage

2. JavaScript Algorithms and Data Structures Certification

Projects: Palindrome Checker, Roman Numeral Converter, Caesar's Cipher, Telephone Number Validator, Cash Register

3. Front End Libraries Certification

Projects: Random Quote Machine, Markdown Previewer, Drum Machine, JavaScript Calculator, Pomodoro Clock

4. Data Visualization Certification

Projects: Bar Chart, Scatterplot Graph, Heat Map, Choropleth Map, Treemap Diagram

5. APIs and Microservices Certification

Projects: Timestamp Microservice, Request Header Parser, URL Shortener, Exercise Tracker, File Metadata Microservice

6. Information Security and Quality Assurance Certification

Projects: Metric-Imperial Converter, Issue Tracker, Personal Library, Stock Price Checker, Anonymous Message Board

Full Stack Development Certification

Once you have earned all 6 of these certifications, you'll be able to claim your Full Stack Development Certification. This final distinction signifies that you’ve completed around 1,800 hours of coding with a wide range of web development tools.
