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.

Coding assessments built for AI and ML engineers
Challenges are generated per domain rather than pulled from a generic pool, covering deep learning, generative AI, NLP and computer vision alongside traditional ML.
The AI Interviewer helps create tailored assessments from expert-designed templates or from scratch, adjusting difficulty and scope in minutes.
Candidates work in interactive notebooks or containerised environments, so the test reflects how AI work is actually done rather than a whiteboard puzzle.
Submitted work is analysed automatically, with scoring on model accuracy and code quality, producing structured evaluation results.
