What Mastra does
Mastra is an open-source, TypeScript-native agent framework aimed at developers who want to build, run, and productionize AI agents and agent-driven applications without switching ecosystems. The core product is the Mastra framework (Apache 2.0-licensed) that provides typed primitives for defining agents, orchestrating workflows, managing memory/state, adding tool access, and tracking/evaluating behavior via observability features like traces, logs, metrics, and datasets. Mastra positions itself as “one framework” that unifies these primitives rather than stitching together separate libraries that were not designed to interoperate.
In addition to the open-source framework, Mastra describes a commercial “platform” used to deploy and operate agents at scale. On April 9, 2026, Mastra states it launched the Mastra platform, including Mastra Studio (cloud-based and self-hosted) for evals/observability/datasets, Mastra Server for deployments, and Memory Gateway for agent memory whether using Mastra or other frameworks.
Mastra’s enterprise-oriented capabilities increasingly focus on operational governance for agent runtimes (for example, adding finer-grained authorization at the per-user/per-resource level over runtime elements like tool calls and MCP servers) and workflow lifecycle features (for example, dynamic workflows that can be added to a live Mastra server without redeploying code).
Target users include TypeScript/JavaScript engineering teams building agentic features inside products (customer-facing agents) and teams building internal developer platforms for other teams or for scaling agent deployments (developer-platform agents). Mastra also markets supporting teams who need agent observability and production controls (e.g., trace review and clustering to identify common failure modes or behaviors).
