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.
Turn plain English into ready-to-run Linux commands at the prompt
Describe what you want to accomplish in ordinary English and receive a Linux command that matches the intent.
The helper works from the command line itself, so you avoid context switching to a browser or documentation site.
A simple keyword prefix lets you call the assistant only when you need it, keeping normal shell usage unchanged.
Setup instructions are distributed through the project's GitHub repository, and the site collects email addresses for release news.
