insights is MIT-licensed and built on JS/TypeScript with a node backend. That's really appealing as a user since it means there's no need to delve into another programming language or huddle with the lawyers to figure out our legal obligations if we make changes. Contrast with the alternatives:

- Metabase is AGPL and built on clojure, making it a hard pass on both counts

- redash and superset have friendlier licenses (bsd-2 and apache-2 respectively) but are built with Python.
