Codecademy is an online interactive platform that offers free coding classes in 9 different programming languages including Python, Java, PHP, jQuery, JavaScript, AngularJS, and Ruby, as well as markup languages HTML and CSS.[4][5] The plaftorm also provides courses for learning command line and Git.[4] In September 2015 Codecademy, in partnership with Periscope, added a series of courses designed to teach SQL, the predominant programming language for database queries.[6] In October 2015, Codecademy created a new course, a class on Java programming. As of January 2014, the site had over 24 million users who had completed over 100 million exercises.[3][7][8] The site has received positive reviews from many blogs and websites, including the New York Times[9] and TechCrunch.[10]

Each individual who joins has their own profile. To motivate users to participate, the site offers feedback, badges for completing exercises, as well as a function that keeps track of a user's total score and total day streak, and displays it to others. There are also CSS and HTML glossaries available within each tutorial.[11] The site allows anyone to create and publish a new course using a Course Creator tool.

Codecademy also provides a forum where enthusiasts, beginners, and advanced coders can come together and help each other. For some courses, there are 'sandboxes' where users can test out their code. There are four main topics: Web (HTML, CSS, JavaScript, and PHP), Ruby, Python, and Miscellaneous.[12]

As part of the Computer Science Education Week held in December 2013, Codecademy launched their first iOS app called "Hour of Code". The app focuses on the basics of programming, including the same content from the website, and it's aimed for people who want to learn programming in a fun way and on the go.[13]


Codecademy was founded in August 2011 by Zach Sims and Ryan Bubinski.[14] Sims dropped out of Columbia University to focus on launching a venture, and Bubinski graduated from Columbia in 2011.[15] The company, headquartered in New York City, raised $2.5 million in Series A funding in October 2011 and $10 million in Series B funding in June 2012.[14][16] The latest round of funding was led by Index Ventures.[17] Crunchbase reports an additional Series C round of funding for an undisclosed amount, by Bloomberg Beta in June 2013.[18]

On 22 July 2014, the site appeared with a new redesigned dashboard.[19]

In August 2015, Codecademy partnered with the White House, willing to host in-person meet-ups for 600 students from disadvantaged women and minority groups over a period of 12 months.[20][21]

Code Year[edit]

Code Year is a free incentive Codecademy program for anyone who is interested in learning how to program. The program intends to help people follow through on a New Year's Resolution to learn how to program, by introducing a new course for every week in 2012.[22] Over 450,000 people took courses in 2012,[23][24] and Codecademy continued the program into 2013.
