As we venture into the realm of multi-agent systems (MAS), it’s essential to understand the diverse programming languages designed specifically for this purpose. In this article, we’ll delve into the world of MAS development by comparing LangGraph, Autogen, and Crewai — three prominent players in the field.

Introduction

Multi-agent systems (MAS) have become increasingly important in various industries. A MAS is a system composed of multiple intelligent agents that interact with each other and their environment to achieve specific goals. Among the many frameworks available for building MAS, LangGraph, Autogen, and Crewai are some of the most popular choices.

As developers or researchers working on a MAS project, choosing the right framework can be overwhelming, especially considering factors such as ease of use, scalability, customization, and integration with AI libraries. This article provides a comparative study of LangGraph, Autogen, and Crewai, highlighting their strengths, weaknesses, and suitability for different applications.
