AutoAgents

A Modern Multi-Agent Framework in Rust

Documentation | Examples | Contributing

---

🚀 Overview

AutoAgents is a cutting-edge multi-agent framework built in Rust that enables the creation of intelligent, autonomous agents powered by Large Language Models (LLMs) and Ractor. Designed for performance, safety, and scalability. AutoAgents provides a robust foundation for building complex AI systems that can reason, act, and collaborate. With AutoAgents you can create Cloud Native Agents, Edge Native Agents and Hybrid Models as well. It is built with a modular architecture with swappable components, Memory layer, Executors can be easily swapped without much rework. With our native WASM compilation support, You can depoloy the agent orchestration directly to Web Browser.

✨ Key Features

🤖 Agent Execution

• Multiple Executors: ReAct (Reasoning + Acting) and Basic executors with streaming support
• Structured Outputs: Type-safe JSON schema validation and custom output types
• Memory Systems: Configurable memory backends (sliding window, persistent storage - Coming Soon)

🔧 Tool Integration

• Custom Tools: Easy integration with derive macros
• WASM Runtime for Tool Execution: Sandboxed tool execution

🏗️ Flexible Architecture

• Provider Agnostic: Support for OpenAI, Anthropic, Ollama, and local models
• Multi-Platform: Native Rust, WASM for browsers, and server deployments
• Multi-Agent: Type-safe pub/sub communication and agent orchestration

🌐 Deployment Options

• Native: High-performance server and desktop applications
• Browser: Run agents directly in web browsers via WebAssembly
• Edge: Local inference with ONNX models

📦 Installation

Development Setup

For contributing to AutoAgents or building from source:

Prerequisites

• Rust (latest stable recommended)
• Cargo package manager
• LeftHook for Git hooks management

Install LeftHook

macOS (using Homebrew):

brew install lefthook

Linux/Windows:

# Using npm
npm install -g lefthook

Clone and Setup

# Clone the repository
git clone https://github.com/liquidos-ai/AutoAgents.git
cd AutoAgents

# Install Git hooks using lefthook
lefthook install

# Build the project
cargo build --release

# Run tests to verify setup
cargo test --all-features

The lefthook configuration will automatically:

• Format code with cargo fmt

    Ok(())
}

#[tokio::main]
async fn main() -> Result<(), Error> {
    // Check if API key is set
    let api_key = std::env::var("OPENAI_API_KEY").unwrap_or("".into());

    // Initialize and configure the LLM client
