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.

The teaching layer that explains every line your AI coding agent writes
Every line your agent writes is explained as it happens, covering what the code does, why it was written that way and the intended goal, in the same window.
A VS Code extension brings the teaching layer to Cursor, Copilot, Claude Code, Codex CLI, Cline, Kilo Code, Windsurf, Antigravity and more without changing your agent.
Plan, Fast, Deep and Recursive modes let you propose before writing, iterate quickly, reason deeply, or let the recursive agent plan multi-step work.
49+ prerequisite-locked topics, projects, graded checkpoints and boss exams inside the IDE, with a hint economy earned by completing topics.
