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.

AI performance reviews and goals that actually get run
Raw feedback from reviews is distilled into individual and company-wide reports that are ready to present, cutting the administrative work of each cycle.
Run 360s, peer reviews, upward reviews, self-assessments, probation check-ins and annual reviews with customizable forms and flexible workflows.
Set company, team and individual goals with auto-calculated progress, then include them automatically in review cycles.
Reminders and review tasks arrive where employees already work, with email automation for those who prefer it.
