OpenHands

Overview

OpenHands is an open-source platform for AI-driven software development. It provides multiple interfaces for autonomous coding agents: a composable Python SDK, a CLI for terminal-based workflows, a local GUI similar to Devin or Jules, and a cloud deployment option. The platform achieved a 77.6% score on the SWE-bench benchmark.

Architecture

The system consists of a Python backend (openhands directory) and React frontend (frontend directory). The core agent SDK is composable and can be used standalone or integrated into larger applications. The platform supports multiple LLM providers through LiteLLM and includes custom harness logic for agent orchestration, tool execution, and multi-step workflows.

Deployment Options

SDK: Composable Python library for defining agents in code, runnable locally or scaled to thousands of agents in the cloud.

CLI: Terminal-based interface familiar to users of Claude Code or Codex, powered by any LLM.

Local GUI: REST API with single-page React application for local development.

Cloud: Hosted deployment at app.all-hands.dev with free tier using Minimax model.

Enterprise: Self-hosted Kubernetes deployment with extended features including Slack/Jira/Linear integrations, multi-user support, RBAC, and collaboration tools.

Key Features

The agent can execute shell commands, browse the web via Playwright, interact with Jupyter notebooks, manage Git repositories, and read/write various document formats. It includes pre-commit hooks, linting, type checking, and comprehensive test suites. Enterprise deployments add authentication via Keycloak, database migrations with Alembic, billing through Stripe, and telemetry with PostHog.

Development

Built with FastAPI, React, Docker, and SQLAlchemy. Uses TanStack Query for frontend data fetching, Poetry for Python dependency management, and supports multiple runtime environments including local, Docker, and Kubernetes. The codebase enforces strict code quality standards with automated pre-commit hooks and CI/CD checks.
