description: >-
  TruLens (the open-source library) is free under Apache 2.0. The legacy TruEra commercial platform
  was sold via enterprise contracts; following the May 2024 Snowflake acquisition, new customer
  commercial access is via Snowflake's pricing rather than standalone TruEra contracts.
notes: TruLens is free OSS; commercial offering is migrating into Snowflake Cortex.
