Bringing Multi-Agent AI to JavaScript with KaibanJS

Introduction

Multi-agent AI systems are redefining automation and decision-making across industries, enabling AI agents to collaborate dynamically to solve complex tasks. While frameworks like CrewAI and AutoGen have popularized multi-agent coordination in Python, JavaScript developers have often found themselves without a dedicated solution. KaibanJS changes that.

KaibanJS is an open-source JavaScript framework designed to orchestrate multi-agent AI systems, allowing developers to define specialized agents, manage tasks, and seamlessly integrate large language models (LLMs) into real-world applications.

Why Multi-Agent AI in JavaScript?

With over 20 million JavaScript developers worldwide, the demand for AI frameworks that integrate seamlessly into Node.js, React, and other JavaScript environments is greater than ever. Traditionally, AI tooling has been centered around Python, leaving JavaScript developers reliant on external APIs or cumbersome adaptations.

KaibanJS eliminates these barriers by enabling:

• Native JavaScript Multi-Agent Systems – No need to switch to Python for AI workflows.
• Real-Time AI Orchestration – Execute AI agents dynamically within JavaScript applications.
• Seamless LLM Integration – Use OpenAI, Anthropic, Mistral, or any LLM provider effortlessly.
• Customizable Agent Behavior – Fine-tune agents with task-specific goals and reasoning capabilities.

How KaibanJS Works

At its core, KaibanJS operates on three key concepts:

1. Agents – AI-powered entities that can reason, take actions, and collaborate on tasks.
2. Tasks – Defined objectives that agents must complete, including specific inputs and expected outputs.
3. Teams – Groups of agents working together, coordinating their roles to achieve complex goals.

Case Study: AI-Powered Market Research

Imagine you need to analyze a company’s business model, funding history, and market position. Instead of manually searching multiple sources, we can deploy a team of AI agents in KaibanJS to automate the research process.

Step 1: Define the Agents

Each agent specializes in a specific area of research:

import { Agent, Task, Team } from 'kaibanjs';
import { TavilySearchResults } from '@langchain/community/tools/tavily_search';

const searchTool = new TavilySearchResults({
    maxResults: 5,
    apiKey: 'ENV_TAVILY_API_KEY',
});

const businessModelAgent = new Agent({
    name: 'Business Model Analyst',
    role: 'Analyze Business Model and Scalability',
    goal: 'Extract and analyze information about the company’s revenue sources and scalability.',
    tools: [searchTool]
});

const fundingAgent = new Agent({
    name: 'Funding Specialist',
    role: 'Research Funding and Growth',
    goal: 'Gather data on funding rounds, investors, and key growth metrics.',
    tools: [searchTool]
});

Step 2: Assign Tasks

Each agent is assigned a task with clear objectives:

const businessModelTask = new Task({
    description: 'Search for information about the business model and scalability of {companyName}.',
    expectedOutput: 'Detailed report on revenue sources and scalability.',
    agent: businessModelAgent
});

const fundingTask = new Task({
    description: 'Search for detailed data on the funding history and growth metrics of {companyName}.',
    expectedOutput: 'Comprehensive report on funding rounds, amounts raised, and investors.',
    agent: fundingAgent
});

Step 3: Coordinate the Team and Execute

We create a team of agents, provide an input company name, and start the workflow:

const team = new Team({
    name: 'Company Research Team',
    agents: [businessModelAgent, fundingAgent],
    tasks: [businessModelTask, fundingTask],
    inputs: { companyName: 'Vercel' },
    env: { OPENAI_API_KEY: 'ENV_OPENAI_API_KEY' }
});

team.start();

This process automates company research, delivering structured insights in a fraction of the time it would take manually.
