# Overview

> This section is for users that would like to use a runtime other than Docker for OpenHands.

<Note>
  This page documents **legacy OpenHands V0** behavior. For the current V1
  sandbox model, see [Sandboxes (V1)](/openhands/usage/sandboxes/overview).
</Note>

<Note>
  These settings are only available in [Local GUI](/openhands/usage/run-openhands/local-setup). OpenHands Cloud uses managed sandbox environments.

A Runtime is an environment where the OpenHands agent can edit files and run
commands.

By default, OpenHands uses a [Docker-based runtime](/openhands/usage/v0/runtimes/V0_docker), running on your local computer.
This means you only have to pay for the LLM you're using, and your code is only ever sent to the LLM.

Additionally, we provide a [Local Runtime](/openhands/usage/v0/runtimes/V0_local) that runs directly on your machine without Docker,
which can be useful in controlled environments like CI pipelines.

## Available Runtimes

OpenHands supports several different runtime environments:

* [Docker Runtime](/openhands/usage/v0/runtimes/V0_docker) - The default runtime that uses Docker containers for isolation (recommended for most users).
* [OpenHands Remote Runtime](/openhands/usage/v0/runtimes/V0_remote) - Cloud-based runtime for parallel execution (beta).
* [Local Runtime](/openhands/usage/v0/runtimes/V0_local) - Direct execution on your local machine without Docker.

### Third-Party Runtimes

The following third-party runtimes are available when you install the `third_party_runtimes` extra:

```bash theme={null}
pip install openhands-ai[third_party_runtimes]
```

* [E2B Runtime](/openhands/usage/v0/runtimes/V0_e2b) - Open source runtime using E2B sandboxes.
* [Modal Runtime](/openhands/usage/v0/runtimes/V0_modal) - Serverless runtime using Modal infrastructure.
* [Runloop Runtime](/openhands/usage/v0/runtimes/V0_runloop) - Cloud runtime using Runloop infrastructure.
* [Daytona Runtime](/openhands/usage/v0/runtimes/V0_daytona) - Development environment runtime using Daytona.

**Note**: These third-party runtimes are supported by their respective developers, not by the OpenHands team. For issues specific to these runtimes, please refer to their documentation or contact their support teams.
