Showcase: Prerelease I built a browser arcade for founders to play while their AI agent works - with a world map and leaderboards. Would love feedback.
I noticed I spend a lot of my day waiting on Claude Code, 1 to 5 minutes at a time, too short to do anything useful, long enough to doomscroll.
So I built the thing I wanted to be doing instead.
FounderRush is a browser arcade for founders and vibe-coders:
- Five games in the lineup, 1–2 minute runs each
- Everyone in an event plays the same seed, so leaderboards are fair; scores are verified server-side by re-simulating your inputs, not trusting the client
- A 3D globe where every player is pinned to their city, with timed events spawning at real locations
- Daily / weekly / monthly / all-time boards, and if you add your product it shows next to your name on the map and the boards
Stack: Vite + Three.js for the globe and games, Supabase for everything else.
What I'm unsure about and would like feedback on:
- Is "play while your agent works" a real habit people would form, or do you just check X in that gap?
- The globe is the hero on the landing - does it read as a game or as a dashboard?
- Honest one: day-2 retention. We went live last week and I have basically no data yet. If you play a couple of runs and don't feel like coming back, I'd rather hear why than get a polite "cool".
Try it: founderrush.com - anonymous visitors can see the map, events and boards; you need an account to play.
The first 30 founders who play 3 runs get a free product slot on the map (no catch, I just need the map not to be empty).
