Run AI hackathons with fair voting and full transparency
Host online AI coding hackathons where participants build with Claude in a browser, submit automatically when time runs out, and vote for the best solution. No judge panels, no politics. Free to run your first event.
Why it works
Run better AI hackathons
No setup friction for participants
Participants join via a link, get a browser editor with Claude built in, and start building. No installs, no account creation, no time wasted on environment setup. The contest starts in seconds.
Fair voting, no judge-panel politics
Every participant reviews and votes. The best code wins based on what the community actually thinks, not what a three-person panel decided in a back room. Transparent, defensible results.
All submissions open for review
After each round, every submission is public: code, AI conversation history, and live preview. Participants learn from each other. Organizers can audit every entry. Nothing is hidden.
How it works
How AI coding contest rounds work
Organizer creates a hackathon round
Write the brief, set the time limit (30 minutes to 2 hours), and share the invite link with participants. Public or private, your choice.
Participants build with an AI assistant
Everyone joins in a browser with Claude available. They build their solution and the contest auto-submits all entries when the timer ends.
Community votes, winner declared
All submissions go live for voting. Every participant reviews and votes for their favourite. The leaderboard updates in real time. Winner declared. No ambiguity, no deliberation delays.
Fair voting and submission reviews, no judge panels
Traditional hackathons hand the result to a three-person panel who deliberates in private. Vibe Coding Game makes every participant a voter. All submissions are public: code, AI conversations, live previews. The community decides what's best. The winner is the one who earned it, not the one who pitched it best.

FAQs
Common questions
How many people can join a single hackathon contest?
There are no participant limits. Whether your hackathon has 20 people or 2,000, every participant gets their own session and submission slot.
Can I run multiple rounds under one event?
Yes. Create a separate contest for each round and share each link in sequence. All submissions are stored, so participants and organizers can review earlier rounds at any point.
Is voting anonymous?
Participants can see all submissions during voting, but the voting tally is revealed only after the voting period closes. This prevents early results from influencing later votes.
Can participants use their own tools, or only the built-in editor?
The contest platform provides a browser editor with Claude built in. Participants use this environment, which ensures equal conditions and makes all submissions reviewable in the same format.
How do I share the contest with participants?
Every contest generates a unique invite link. Share it via email, Discord, Slack, your event website, or anywhere your participants are. No account required to join.
Can we make a hackathon round public so anyone can join?
Yes. By default, anyone with the link can join. You control whether the link is shared publicly or kept private to registered participants.
