What is OpenHands
OpenHands is anAI programming toolthat supports multi-agent collaboration to improve development efficiency and reduce developers' coding workload. OpenHands interacts with the environment by writing code, interacting with the command line, and browsing the web. OpenHands provides powerful interaction mechanisms, a secure sandbox environment, multi-agent collaboration capabilities, and a comprehensive evaluation framework, supporting users in developing new agents, secure code execution, coordination among multiple agents, and evaluation on various tasks. OpenHands covers 15 benchmarks across multiple domains such as software engineering and web browsing, providing strong support for research and applications in academia and industry.
Main features of OpenHands
- Code writing and modification: Automatically generates code snippets that meet project requirements and modifies them.
- Command-line operations: Supports executing various command-line operations to help complete project building, testing, and deployment.
- Web resource retrieval: Integrates web browsing functionality to automatically retrieve resources and information needed for development.
- API call integration: Simplifies interaction with external services and supports integration of various APIs.
- Code snippet copying and application: Copies code snippets from developer communities such as StackOverflow and applies and adjusts them according to requirements.
Technical principles of OpenHands
- Event stream architecture: Manages the interaction between agents and the environment based on an event stream, including agent actions and environment observations. The state structure encapsulates all relevant information needed for agent execution, such as the event stream and LLM call costs.
- Runtime environment
- Docker sandbox: Launches a securely isolated Docker container sandbox for each task session, and all actions are executed in the sandbox.
- Action execution API: The API server runs in the Docker sandbox and handles actions such as command execution, Python code execution, and web browsing.
- Arbitrary Docker image support: Supports agents running on any operating system and software environment, implemented via a runtime based on arbitrary Docker images.
- Agent skills: The AgentSkills library provides practical functions that some basic tools cannot achieve, such as file editing and document reading, facilitating community contributions and agent use.
- Multi-agent delegation: Supports one agent delegating specific subtasks to another agent for execution, enabling collaboration among multiple agents.

Application scenarios of OpenHands
- Software development: Automatically generates code frameworks to quickly create initial files and code structures for new projects, such as generating a Python Flask project's
app.pyandrequirements.txtfiles, allowing developers to directly write core business logic. - Web browsing and information acquisition: Automatically collects news data by gathering news reports on specific events from multiple websites, extracting information such as titles, times, and content, and organizing them into tables for researchers to analyze.
- Assisted decision-making: Analyze market data and generate reports including market size, growth trends, and competitive landscape to help executives make business decisions.
- Research and Innovation: Optimize experimental design to provide multiple design options for biological experiments, help researchers determine experimental parameters and procedures, and improve experimental success rates and innovation.
