Mastra – Open-source JS agent framework, by the developers of Gatsby

Mastra is a robust Typescript framework designed for building AI applications efficiently. It offers key elements like workflows, agents, RAG, integrations, and evals. Users can easily run Mastra locally or deploy it on a serverless cloud. Notably, Mastra leverages the Vercel AI SDK for model routing and supports various LLM providers such as OpenAI, Anthropic, and Google Gemini. The framework’s agents enable seamless interaction with LLM models, integrations, and knowledge bases. Additionally, Mastra provides tools for executing typed functions, workflows for creating state machines, and a unique approach to knowledge base construction through RAG. Quick setup instructions and opportunities for contribution are also highlighted in the content.
