Learn to code free with hands-on lessons and instant playgrounds
Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.

Learn to code by doing, with AI support inside every lesson
Instead of long tutorials, the platform breaks programming into short exercises you complete directly in the browser.
AI assistance is woven into exercises so you can ask for a hint or explanation at the exact moment you get stuck, rather than waiting for a mentor.
The learning experience is designed to work well on a phone, so short practice sessions fit into a commute or a lunch break.
Topics build on each other, moving from core syntax and logic toward problem solving and real project-style tasks.
