Finding the 'Aha Moment': Event Tracking for Vibe-Coded MVPs

I vibe-coded a small, deliberately ridiculous game and shipped it on Vercel - then used it as the test bed for something more serious: how to instrument event tracking for an MVP with Mixpanel. This isn't a Mixpanel sales pitch. It's the minimum viable setup: what to track, what to ignore, where the legal questions around event data actually bite, and how to diagram the "AHA moment" - the one action that predicts whether a user sticks around - so you're not drowning in vanity events before you have vanity users. What's covered: → Mixpanel setup — the lean version, not the enterprise version → Legal basics you can't skip (consent, PII, what "anonymous" doesn't mean) → Diagramming the AHA moment / activation event for your own product Built for founders and PMs who'd rather instrument five events correctly than fifty events badly. 🔗 Website: https://ishchuk.eu 🔗 Agency: https://deuce.works 🔗 LinkedIn: https://www.linkedin.com/in/geneishchuk/ #Mixpanel #ProductAnalytics #EventTracking #MVP #VibeCoding #Vercel #ProductManagement #StartupAnalytics #AhaMoment #NoCode #BuildInPublic #SaaS
