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.

Automated reference checks and skills assessments for smarter hiring
Collect and summarise candidate references through a structured, automated workflow instead of manual calls and emails.
Run role-relevant skills and competency assessments so hiring teams can verify practical ability, not just claims on a CV.
Structured questionnaires and consistency checks help surface suspicious or low-quality references and reduce hiring risk.
Turn raw referee responses into clear, comparable reports that give hiring managers evidence for decisions.
