What Eko is
Eko is an open-source intelligent agent framework for developers, created by the FellouAI team. It lets you build agent workflows using a mix of natural language and code, covering everything from simple commands to complex, multi-step processes. It ships with built-in tools such as web content extraction, command execution, and file export, and you can add your own custom tools to extend it. It uses hierarchical planning that separates offline planning from execution, so task plans stay reusable and easy to modify. It supports multiple large language models such as ChatGPT and Claude 3.5, letting you switch as needed.
What you can do with it

Who it is for
- Developers automating browser or desktop tasks

What to watch out for
It is a developer framework, so expect a learning curve; you will get the most from it if you are comfortable reading documentation and writing some code. The core is open source and free, but some advanced features or customization services may require payment, and those terms can change. As with any open-source project, maintenance and updates are not guaranteed, so pin versions and do not build critical systems on unreviewed changes. Test workflows carefully before you let agents take real actions. When quality matters, export a small draft first to confirm the result before producing the final file.
