Codecademy

Previously backed by the White House, Codecademy is dedicated to teaching people how to code—and it’s available for free. While other online coding courses are a “learn at your own pace” environment, Codecademy motivates learners to keep a fast pace using supportive groups and a gamified points system.

The school offers courses on a number of languages—including PHP, Phython and Ruby—and students are often already building and deploying projects by the time they finish their course.
