Strengths

Apache 2.0 plus enterprise path
Fast growth
Modern DX

Practitioner note

Promising TypeScript-first framework for product teams that want modern developer ergonomics, but enterprise proof points are still earlier than older stacks.

Warning

Mastra: Mastra uses a dual-license model: most of the repo is Apache 2.0, while code under ee/ directories uses the Mastra Enterprise License.
