NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

Mastra is an open-source, TypeScript-native framework for building AI applications and agents. It offers a graph-based workflow engine, unified access to a variety of LLM providers, human-in-the-loop suspension and resumption, as well as RAG and memory primitives. It also includes MCP server authoring and built-in tooling for evaluation and observability, supported by clear developer documentation. Mastra provides an alternative to Python-heavy stacks, allowing teams to build feature-rich AI capabilities directly within existing web ecosystems such as Node.js or Next.js. It's worth evaluating for teams already invested in the TypeScript ecosystem who want to avoid switching to Python for their AI layer.
