How to Track Daily Active Users in Supabase — Without Writing SQL
Managing DAU in Supabase is tricky because user data is split between the auth and public schemas. You have to navigate UUID joins and Row Level Security policies just to count active sessions. Most founders struggle to link auth.users to their own activity tables.
