Mastra NPM | npm.io

Mastra Framework

Mastra lets you prototype and productionize AI features quickly with a modern JS/TS stack.

Workflows: Chain calls to OpenAI, Anthropic, Google. Pipe output between steps. Create graphs with workflow.addStep() and step.connect().
RAG pipeline: Sync data into a vector DB (Pinecone). Mastra integrates with 50+ SaaS services, web scrapers, etc.
Agents: provide OpenAI Assistants with tools, workflows, synced data.

Mastra uses Inngest and Prisma to store and sync data into vector databases. It includes an admin panel for exploring data, a playground for testing actions, a chat UI for agents, and a visual workflow builder with variables, conditions, and branching.

The setup is completely self- contained and runs on your local machine. In production, you can self-host or deploy to Vercel/Netlify.

Quick Start

Node.js (version 20 or later)
pnpm (version 9.7.0 or later)

Configuration

After initialization, you'll find an mastra.config.ts file in your project root. You can find the full list of configuration options in the Mastra config docs.

Deployment

Mastra's data syncing infrastructure is designed for Next.js sites running on serverless hosting providers like Vercel or Netlify.

Job queues are managed with Inngest, which can be self-hosted or run as a managed service.

Logs are stored in Upstash.
