About OpenManus
OpenManus is an open-source AI agent framework developed by FoundationAgents that enables developers to build, customize, and deploy general-purpose autonomous agents. It provides a flexible architecture for creating agents that can plan, reason, and execute multi-step tasks using a variety of tools and integrations. The project is community-driven and designed to be extensible, making it suitable for research, prototyping, and production use cases alike.
- General-Purpose Agent Framework: Build agents capable of handling diverse tasks including web browsing, code execution, file management, and more out of the box.
- Multi-Step Task Planning: Agents autonomously decompose complex goals into sub-tasks and execute them sequentially or in parallel.
- Tool Integration: Easily plug in custom tools or use built-in integrations for web search, code interpreters, and file systems.
- Multi-Agent Support: Orchestrate multiple specialized agents working together to solve complex problems.
- Open-Source & Extensible: Clone the repository, install dependencies, and start building custom agents with a clean Python API.
- LLM Agnostic: Supports multiple large language model backends, allowing developers to swap models based on task requirements or cost.
- Community-Driven Development: Active GitHub community with contributions, issues, and discussions to accelerate development.
- Easy Setup: Get started by cloning the repo and following the quickstart guide to run your first agent in minutes.
