## The Catch

Loud: $0 forever path is dbt Core OSS Apache-2.0 (local/self-host). Platform Developer Free forever is real but capped (1 seat / 1 project / 3k successful models/mo); Starter $100/user/mo. Semantic Layer advanced is Cloud-paid — do not pitch Platform as the free hatch. Distinct from Flyte CD / ZenML CA. Skills Apache-2.0.
