Real-World Coding Challenges
Build your training program on a ready-to-use library of real-world challenges — working projects with automated tests that show whether a skill actually stuck.
Explore Challenges →Run practical training for your team on real-world coding challenges — automated evaluation and analytics show measurable skill progress.
Build your training program on a ready-to-use library of real-world challenges — working projects with automated tests that show whether a skill actually stuck.
Explore Challenges →Run timed, scenario-based coding events that simulate real projects — a focused way for teams to practice under constraints and see where their skills stand.
Explore Contests →Assign a learning path or a challenge to groups or individual team members, with due dates and per-person extensions. Autograde against a passing score or review submissions by hand — with per-attempt detail down to time spent and AI prompts used.
Build structured tracks that pair short lessons with required challenges. Alex teaches each lesson and checks understanding before practice — and can generate a tailored path for a specific team member, ready to assign in one click.
Explore Learning Paths →Alex's Trainer mode runs your program conversationally: review individual progress, compare group performance, create assignments, and set up contests — the assistant pulls live data and fills in the details for you.
Evaluate skills automatically, monitor improvement, and measure real coding outcomes so training targets what matters on the job. In a world where AI can write the code, see what your team can actually build — and where it struggles collectively, whether that's API design, async patterns, or debugging.
Generate snapshot reports for group statistics, contest leaderboards, or learning-path progress — skill coverage, strengths and weaknesses, training priorities, and per-person detail. Export any report as PDF or CSV.
