An open-source framework by Cognition for building autonomous AI agents that can interpret complex user requests and execute tasks like code editing, command execution, and web browsing within a secure sandbox.

Try it out

OpenHands is an open-source framework for creating and orchestrating autonomous AI agents powered by large language models (LLMs). Developed by Cognition, the company behind the Devin AI agent, it provides developers with the core building blocks to define tasks, model agent behavior, and execute complex workflows securely on a local machine. The framework is targeted at AI researchers and engineers who want to build custom agents for specialized tasks ranging from software development to data analysis. Its unique value lies in its transparent, extensible architecture and its focus on security through a sandboxed Docker environment, offering a powerful alternative to closed-source agent platforms. This allows for deep customization and a clear understanding of the agent's decision-making process.

Pros

  • Fully open-source (Apache 2.0 license), allowing for complete transparency and customization.
  • Operates in a secure Docker sandbox by default, isolating agent actions from the host system.
  • Developed by Cognition, the respected team behind the Devin AI software engineer agent.
  • Flexible architecture supports various LLMs (GPT-4, Claude, etc.) as the agent's reasoning engine.
  • Enables detailed trajectory review, allowing developers to debug and analyze an agent's step-by-step actions.

Cons

  • Requires significant technical expertise (Python, Docker, LLM APIs) for setup and effective use.
  • As a framework, it is not an out-of-the-box solution and requires development effort to build a functional agent.
  • Performance is highly dependent on the chosen LLM, which can incur significant API costs.
  • Being a new project, its documentation, community support, and pre-built examples are still evolving.

Key features

  • Sandboxed execution environment using Docker
  • Extensible agent and model architecture
  • Task planning and execution loop
  • Support for multiple third-party LLM APIs
  • Tooling for Shell command execution
  • File system operations (read, write, edit) within the sandbox
  • Web browsing capability for information gathering
  • Trajectory logging for debugging and analysis
