Everything you need to run great coding contests
From AI-assisted coding to peer voting — built for teams that want smarter hiring, stronger learning, and a real engineering culture.
Coding Contests
Create timed coding challenges in seconds. Set custom tasks, share an invite link, and let participants compete live with auto-submit when the clock runs out.
AI Coding Assistant
Every contestant gets Claude Haiku built right into their session — helping them scaffold ideas, debug code, and ship faster without doing the thinking for them.
Live Browser Editor
A fully browser-based code editor with real-time preview. No installs, no setup. Participants just open the link and start coding — HTML, CSS, and JavaScript out of the box.
Peer Voting & Review
When time's up, every submission goes public. Participants vote on each other's work, turning the end of a contest into a community-driven code review.
Team Contests
Organize contests for your whole team. Invite members, run private challenges, and build a culture of friendly competition that keeps developers engaged.
Developer Hiring
Replace take-home assignments with live contests. See how candidates actually code — under pressure, with AI tools — the way they'll work at your company.
