Love Hotjar. Totally transformed my approach to client analytics (note: I wasn't paid to say this). If you make web sites for other people, give it a shot.

I see they have support for SPA's in their roadmap, does anyone know how well this will eventually work with ReactJS apps? Any beta test experience you can share?

Easily the most insightful analytics tool we use. It helps build empathy for your users like none other!

Cool, I'll ask the devs and CTO if they want to look into this
