OpenManus is an open-source intelligent agent project aimed at achieving functionalities similar to Manus through open-source means, but without requiring an invitation code. Developed collaboratively by multiple developers, it leverages a powerful language model and a flexible plugin system to quickly implement various complex tasks. The main advantages of OpenManus are that it is open-source, free, and easily extensible, making it suitable for developers and researchers for secondary development and research. The project background stems from a need to improve existing intelligent agent tools, with the goal of creating a completely open and easy-to-use intelligent agent platform.
