I've been using Grain for about three weeks on the Tier 2 plan, tracking two sites. Setup was quick, and I had events flowing within minutes.

What I appreciate most is how readable the dashboard is. Top events, visitor sources, bounce rate, global activity - it's all right there without digging through layers of menus. Coming from Google Analytics, this is a breath of fresh air - no wrestling with GA4's event configuration or getting lost in endless reports.

The cookieless tracking is a big plus since GDPR compliance matters to us. It's running in cookieless consent mode and still giving meaningful data - 25K+ events tracked, user journey insights, and clear conversion attribution. The Tracks feature is great for seeing how visitors actually move through a site and where they drop off.

I'm also using the Campaigns feature for UTM tracking ahead of a trade show, and the AI assistant (Kai) is a nice touch for quick data questions without having to build custom queries.

On the Tier 2 plan with 150K MAUs, I'm barely using 1% of my limits, so plenty of room to grow. Heatmaps included at this tier are a nice bonus too.

The founder is responsive and the product is actively developed with regular updates. Solid investment.
