About AuthCost

An independent ledger of auth and identity pricing: base plan plus MAU/MRU and SSO fees, with the source and check date on every row.

How it’s kept. Prices are read only from vendors’ own pricing pages, re-checked by a script and logged when they change. Unknowns stay blank; we never estimate a price. Details: methodology.
How it’s paid for. The ledger, calculator, comparisons and data are free. Revenue comes from optional Pro alerts and labeled newsletter sponsor slots. There are no affiliate links today. No one pays for placement.
Who runs it. AuthCost is published by the same independent operator as the pricing ledgers O11y Watch, Ratecard and VPSLedger. Source code: github.com/Basileion/authcost.
