Runtime & OrchestrationOpen source · Apache-2.0 (core); ee/ under Mastra Enterprise LicenseSelf-hosted
TypeScript agent framework with workflows, RAG and eval primitives.
Mastra is a TypeScript agent framework whose core is Apache-2.0, but whose ee/ directory ships under the separate Mastra Enterprise License, so it is not a purely Apache-2.0 project.
Caveat: Mixed licensing: production commercial use of the ee/ enterprise directory requires a Mastra license. GitHub reports the repository license as NOASSERTION for this reason.
