1. License: BSD-3-Clause

Status: accepted · 2026-10-22

Context. fitwise builds on lmfit, SciPy and NumPy, which are all BSD-licensed. Its users include companies that embed fits in measurement software.

Decision. fitwise is licensed under BSD-3-Clause.

Consequences. The license matches the rest of the stack, so downstream users have no additional license review. Code can move between fitwise and its dependencies in both directions.
