About Mastra
Mastra is a TypeScript-first framework designed for building production AI agents and applications. It provides typed agents, graph-based workflows, memory persistence, and built-in observability including metrics, logs, traces, and evaluations. The framework supports model routing across over 90 providers, MCP servers, and Node-compatible deployments, enabling teams to standardize multi-model access while maintaining deep observability for reliability, performance, and cost control. Developers define typed agents with instructions, tools, and models in a single file, then compose complex workflows using control-flow primitives like then, branch, and parallel. Memory can be persisted and retrieved from APIs, databases, or files to maintain context, while built-in tracing captures tokens, logs, and tool calls for debugging and iteration. Mastra Studio offers a visual interface to inspect workflow graphs, run details, traces, and eval scores, alongside memory snapshots and inputs/outputs, facilitating rapid debugging and regression checks. Deployments are streamlined to Hono servers or cloud providers with minimal configuration changes, supporting integrations into Next.js, React, or Node applications. Teams use Mastra for customer support copilots, internal Slack automation agents, developer SRE monitoring, and onboarding assistants embedded in web apps.
