Headless Mode

You can run OpenHands with a single command, without starting the web application. This makes it easy to write scripts and automate tasks with OpenHands.

This is different from CLI Mode, which is interactive, and better for active development.

With Python​

To run OpenHands in headless mode with Python:

  1. Ensure you have followed the Development setup instructions.
  2. Run the following command:
poetry run python -m openhands.core.main -t "write a bash script that prints hi"

You'll need to be sure to set your model, API key, and other settings via environment variables or the config.toml file.

With Docker​

To run OpenHands in Headless mode with Docker:

  1. Set the following environmental variables in your terminal:
  • WORKSPACE_BASE to the directory you want OpenHands to edit (Ex: export WORKSPACE_BASE=$(pwd)/workspace).
  • LLM_MODEL to the model to use (Ex: export LLM_MODEL="anthropic/claude-3-5-sonnet-20241022").
  • LLM_API_KEY to the API key (Ex: export LLM_API_KEY="sk_test_12345").
  1. Run the following Docker command:
docker run -it \
    --pull=always \
    -e SANDBOX_RUNTIME_CONTAINER_IMAGE=docker.all-hands.dev/all-hands-ai/runtime:0.20-nikolaik \
    -e SANDBOX_USER_ID=$(id -u) \
    -e WORKSPACE_MOUNT_PATH=$WORKSPACE_BASE \
    -e LLM_API_KEY=$LLM_API_KEY \
    -e LLM_MODEL=$LLM_MODEL \
    -e LOG_ALL_EVENTS=true \
    -v $WORKSPACE_BASE:/opt/workspace_base \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v ~/.openhands-state:/.openhands-state \
    --add-host host.docker.internal:host-gateway \
    --name openhands-app-$(date +%Y%m%d%H%M%S) \
    docker.all-hands.dev/all-hands-ai/openhands:0.20 \
    python -m openhands.core.main -t "write a bash script that prints hi"

Advanced Headless Configurations​

To view all available configuration options for headless mode, run the Python command with the --help flag.

Additional Logs​
