Hi @amooW6ojoh,
Welcome to the Auth0 Community!
Yes, what you see is correct on our pricing page. The Essentials and Professional plans have various custom tiers available depending on the number of monthly active users. There is a sliding scale to select your monthly active users, which will reflect the price accordingly. See below for 1000 MAUs:
(Reference: Pricing - Auth0)
If you have 10,000 users who log in at least once per month, the free tier will be sufficient to support all of your users, and you will still have 15k extra remaining.
I hope this helps!
Let me know if you have any further questions.
Thanks,
Rueben
