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.
Beat the ATS with scoring logic built by ATS engineers
See the raw text a parser extracts from your file, including merged columns, missing sections, and unrecognized headings — before you optimize anything.
Paste a job description and get a scored comparison that separates strong matches, partial matches, and missing skills so you know exactly why calls are not coming.
One click rewrites your resume for the target role, adapting wording and filling skill gaps based on your real background rather than fabricating experience.
Scans your summary and work history for phrases typical of AI-written resumes, rewrites them, and shows every sentence it changed.
