Topaz Plans Pricing
Topaz itself is free and open source under Apache-2.0 (github.com/aserto-dev/topaz). You self-host the authorizer (Docker or binary); there is no license fee and no per-decision charge from the project - your only cost is the infrastructure you run it on. There is no paid Topaz tier. The commercial offering is Aserto, a hosted control plane built on Topaz that centrally manages policies, directory data, and decision logs across many deployed authorizers; Aserto is a separate product with its own tiers (typically a free developer tier plus usage/seat-based paid and enterprise plans - contact Aserto for current rates). Exact Aserto rates are not reconciled here.
