Live competitions
Solve algorithmic challenges in real time, with auto-graded test cases and a Python / JS / TS editor built right into the page.
Hackhub is the live hackathon arena for young builders: timed code challenges, project drops, team battles, and a leaderboard that makes every smart move visible.
Teams ship a working idea, present the demo, and defend every design decision in front of mentors.
Hackhub is the competition platform of Algorithmics — the international school of programming for ages 6 to 18. We inspire kids and teens to build the future through coding, creativity, and real-world projects.
Students learn coding, design, and problem-solving for the real world.
Join a network of learners and mentors from over 95 countries.
