What is mastra?

Mastra is a comprehensive open-source framework designed to streamline the development of AI applications. Built on TypeScript, it provides foundational capabilities for creating intelligent agents, managing complex workflows, and seamlessly integrating third-party tools. The platform supports routing and deployment across multiple models including OpenAI, Anthropic, and Google Gemini, with an architecture that encompasses deterministic workflows, memory management, retrieval-augmented generation (RAG), and observability, enabling developers to easily build scalable, production-grade AI solutions.

Key Features of mastra?

Unified Model Routing
Support for multiple LLM providers via Vercel's AI SDK, enabling flexible model selection and deployment within a single interface.
Deterministic Workflows
Graph-based workflows with support for branching, error handling, and suspend/resume capabilities to orchestrate complex tasks.
Agent Memory and Tool Calling
Persistent memory combined with function tool integration, allowing agents to retain context and invoke external functions or APIs.
Retrieval-Augmented Generation (RAG)
Enables knowledge base construction and evidence-based responses through document chunking, embeddings, and vector retrieval.
Scalable Tool and API Integration
Automatically generates type-safe clients for third-party APIs, enabling seamless integration of tools into agents and workflows.
Observability and Evaluation Metrics
Built-in tracing, logging, and automated evaluation metrics for debugging, performance monitoring, and output quality assessment.
