Hi there @TheLegenD! Thanks for reaching out and apologies for the delay in response! The free plan includes 100 DAU per month.
As described on our pricing page, Daily Active Users (DAU) are defined as users who authenticate or refresh their tokens ("login") during a given day. Every day that user logs in using ZITADEL, they are considered a unique daily active user. To calculate the monthly quota, we take the sum of DAU over a given month.
The example outlined on our pricing page also provides a bit more context: Example: If I log in on April 1st, I am one DAU. When I log in on April 2nd, it counts as a second DAU and so on. If I log in 20 days during a given month, I am considered 20 DAU's.
