Mastra

Code-First Frameworks

TypeScript-First Edge Agent Framework

Maintained by Mastra Corp

Core Architecture

Mastra is a TypeScript-native framework built on modular engine layers. It compiles to zero-dependency JavaScript bundle files, making it optimized for edge runtime servers, Vercel Functions, and Cloudflare Workers. It implements lightweight state stores, typed schema tool integrations, and async event triggers.

How to Use & Configuration

code_example.tstypescript

import { Agent } from "mastra";

const supportAgent = new Agent({
  name: "SupportAgent",
  model: { provider: "openai", name: "gpt-4o" },
  instructions: "Help customers solve technical issues.",
  tools: {
    fetchSystemStatus: async () => ({ status: "operational" })
  }
});

const response = await supportAgent.execute("Is the DB up?");
console.log(response.text);

Technology Payment Plans

Open Source CoreFree

Free and open-source under the MIT license. Highly optimized for low-latency Vercel/Cloudflare deployments.

Enterprise ConsultingCustom

Custom deployment architectures, security compliance auditing, and priority support SLAs.

Key Advantages

•TypeScript first, providing complete autocomplete and compile-time checks
•Ideal for low-latency serverless deployment on Vercel/Cloudflare Workers
•No python dependencies, making it very lightweight for Node.js backends

Comparison Analysis

Technology	Primary Use Case & Engineering Focus
Mastra	Low-latency edge runtime, zero-dependency Node packages, and native TypeScript
LangGraph JS	LangGraph JS is feature-rich but heavy and complex; Mastra focuses on minimal bundle sizes and developer ergonomics.
