OpenHands

OpenHands is an open-source platform for AI software agents, and one of the most-starred projects in the space. Its agents do what a developer does: modify code, run commands, browse the web, call APIs, and yes, copy a snippet from Stack Overflow when that is the right answer.

What you get

• A sandboxed runtime. Each agent session runs in a container with a real shell, a browser, and a Jupyter kernel, so it can execute and verify its own work.
• Model agnosticism. Use any major provider or a local model — nothing is hard-wired to one vendor.
• Multiple entry points. A web UI, a CLI, a GitHub Action that resolves issues, and a headless mode for scripted use.
• Microagents. Repository-specific instructions that teach the agent your conventions and are checked into the repo.
• Self-hosting. Run the whole thing with Docker on your own infrastructure, which matters when code cannot leave the building.

Options

The open-source project is free under the MIT licence. All Hands also offers a managed cloud with the same agent, for teams that would rather not operate it. A strong default if you want agentic coding without vendor lock-in.
