Show HN: I built a tool for vibe-coding multiplayer games, polls, quizzes

2•molefrog•1h ago

Hi HN, so I've been working on this alternative to Slido/Mentimeter that allows people to connect to your slides and collaborate in real-time. But instead of using predefined polls, I made a coding agent that builds it for you.

I spend weeks trying to teach it how to use a local-first db called InstantDB and how to produce decent designs. I also made sure it can use things like sound or read from motion sensor (if connected via phone).

I've put together a collection of premade apps that you can clone and use right away (I plan to add more including apps built by other users).

Would love to learn more about the sound and motion sensor. How did implementing that go?

I basically made a collection of docs that the agent can read from: how to animate counters, how to emit particles, how to do 2d physics etc. and preinstalled proven packages for that. One file per topic, very opinionated and stripped down to the essentials. The motion sensor doc lists libraries and hooks it must use, also some recipes like shake detection and so on.
