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.
Screen recorder that captures bugs with full technical context
Record your screen or grab a screenshot from the browser extension, the iOS app, or the Mac app.
Available console logs, network requests, user events, and device details ride along with every recording.
Automatic title, summary, and reproduction steps give developers and agents a clear place to begin.
Push Jams into Linear, Jira, or Slack for triage, or into AI coding tools for investigation.
