It has about 4,600 GitHub stars and SDKs for the main languages. Cerbos Hub adds a policy editor, CI builds, rollout to every decision point, audit logs and multi-tenant policies. The PDP is free forever under Apache-2.0 with no account. Hub has a free Proof of Concept tier for 100 monthly active principals, Development from $25 a month (100 principals included, three-month free trial) and Production from $933 a month with 5,000 included; extra principals start at $0.25 each and fall with volume. Enterprise is custom. Paying yearly saves 15%.
