The general AI agent that gets things done

Manus is a general-purpose autonomous AI agent that can plan, reason, and execute complex multi-step tasks across different domains. It combines a large language model with tool use capabilities including web browsing, code execution, file management, and API integrations to accomplish tasks from research to data analysis to content creation.

Build and deploy autonomous AI agents

AutoGPT is the pioneering open-source autonomous AI agent platform that started the autonomous agent movement. It enables users to create AI agents that can plan multi-step tasks, use tools, browse the web, and execute autonomously toward defined goals. Now includes a marketplace for community-built agent templates and blocks.

Multi-agent orchestration framework

CrewAI is a leading open-source framework for orchestrating role-based AI agents that work together as a crew. It enables developers to define specialized agents with distinct roles, tools, and goals, then orchestrate them to collaborate on complex tasks — from research workflows to data pipelines to automated content production.

Build stateful, multi-actor agent applications

LangGraph is a framework by LangChain for building stateful, multi-actor agent applications with LLMs. It provides a graph-based approach to designing agent workflows with cycles, branching, and human-in-the-loop patterns. Designed for production agent systems requiring reliability and controllability in complex agent interactions.
