GeeksWithGeeks is a free library of programming tutorials. Every course is split into short segments that you can read as a page or play as 30-second shorts.
Lessons are available in English and Hindi, and the language switch follows you across the whole site. Code samples stay the same in every language.
Some courses are complete and hand-written; others are still being written and show placeholder lessons until their full content is ready. The home page lets you show only the courses that are available now.
The site is open source. Found a mistake or want a topic added? Open an issue on GitHub.
