Monthly active users (MAU)
Monthly active users is the number of distinct people who sign in to or use a product in a month, and it's how many login and backend providers set their plan limits.
What it means in practice
MAU drives the bill on most backend platforms: Supabase Pro includes 100,000 and Firebase covers 50,000 for logins before charges start.
Marshall Tech forecasts MAU at launch and at a year out when pricing a product's running costs for a client.
Where this shows up in our work
