BUSL-1.1 · Source available (not OSI-approved)
Not open source. Source-available with a time delay: use is restricted — typically barring competing production offerings — until a stated change date, after which the code converts to an open license such as Apache-2.0. The specific Additional Use Grant determines what you may actually do.
The same license produces different obligations depending on whether the software is distributed, hosted, or kept internal. This is the distinction most dependency scanners collapse.

As a build-time dependency it is a different question.
BUSL-1.1 appears as a dev dependency, so it is not part of the artifact you ship. Distribution-triggered obligations do not arise. Tools that emit code into your output, such as code generators, are a separate case worth checking individually.
