Open Source
OpenHands (formerly OpenDevin) is an open-source platform for building AI agents that behave like software engineers — they can modify code, run commands in a sandboxed environment, browse the web, and call APIs to accomplish development tasks end to end. It supports both a full agentic coding workflow and a CLI mode, and has become one of the most popular open-source alternatives to closed AI coding agents, with over 80,000 GitHub stars. It's a good starting point for teams wanting a self-hostable, extensible agent framework rather than a black-box SaaS coding assistant.
