Quick Answer
If you want a straight swap for Codecademy that costs nothing, use freeCodeCamp. It is fully free with no paywall, it is project-based, and it hands you real certifications. That is the pick for most people. From there it depends on your goal: The Odin Project for web development depth, Boot.dev for backend, Scrimba if you want the interactive in-browser feel Codecademy is known for, Khan Academy if you are starting from zero, and Full Stack Open if you already know the basics and want modern full-stack.
