> Open-source general AI agent framework replicating Manus without invite codes

OpenManus is an open-source autonomous agent framework created by members of the MetaGPT team as an open alternative to Manus AI. It uses LLMs paired with browser automation tools like Browser Use to execute complex tasks, web interactions, and multi-step workflows locally. It gives developers full control over model configuration and tool calling without waiting for proprietary invite lists.

## What it is for

- Run automated multi-step web research and data gathering workflows
- Automate complex web browser actions and form submissions via Browser Use
- Prototype custom autonomous agents that interact with external MCP servers
- Experiment with reinforcement learning tuning for LLM agents

## Features

- Browser automation powered by Browser Use CLI 3.0 via MCP integration
- Support for custom LLM providers and models configured via TOML
- Model Context Protocol (MCP) server support for modular tooling
- Local execution attaching directly to local Chrome/Chromium or remote browsers
- Sandboxed execution and multi-agent flow orchestration scripts
- Companion OpenManus-RL project for GRPO and RL-based agent tuning

## Pricing

Open source. Free and open source; requires your own LLM API keys.
