# Choose Your Path

> Decide how to use Scale Gymnasium based on your needs

Scale Gymnasium offers two distinct ways to work with environments. Choose the path that matches your use case.

## Decision Tree

```
What's your primary goal?
│
├─► Explore environments, prototype agents, or demo capabilities
│   └─► Use the Gymnasium Web UI
│
└─► Run large-scale evaluations, integrate into CI/CD, or custom training
    └─► Use Docker Images
```

## Comparison

| Aspect              | Gymnasium Web UI                    | Docker Images                    |
| ------------------- | ----------------------------------- | -------------------------------- |
| **Agent Loop**      | Built-in — Scale provides execution | Bring your own — you implement   |
| **Setup Time**      | Instant                             | Requires Docker setup            |
| **Best For**        | Exploration, prototyping, demos     | Production, evaluation, training |
| **Scaling**         | Single sessions                     | Parallel containers              |
| **Verifier Access** | All environments                    | Website Environments only        |
| **Customization**   | Use provided interface              | Full API control                 |

## Path 1: Gymnasium Web UI

<Info>
  **Best for:** Researchers who want to explore environments, test agent behaviors, or demonstrate capabilities without infrastructure setup.
</Info>

Access the Web UI at [gym.scale.com](https://gym.scale.com).

The Web UI provides:

* **Visual environment browser** — See all available environments and their capabilities
* **Built-in agent loop executor** — Run agent models against tasks without writing code
* **Real-time state inspection** — Watch database and application state change
* **Integrated verifier** — Check task completion with one click
* **Sample tasks** — Pre-built prompts and verification criteria

## Path 2: Docker Images

<Info>
  **Best for:** Researchers running large-scale evaluations, integrating into training pipelines, or needing full programmatic control.
</Info>

Docker images provide:

* **Self-hosted environments** — Run on your own infrastructure
* **Full API access** — Programmatic control over all environment features
* **Parallel execution** — Spin up multiple containers for scale
* **CI/CD integration** — Automate evaluation in your pipelines
* **Custom agent loops** — Use your own execution framework

### What You'll Need

* Docker installed (version 20.10+)
* Docker images from Scale (contact Scale to receive)
* Your own agent loop implementation

## Environment Availability

All three environment types are available through both paths:

| Environment              | Web UI        | Docker        |
| ------------------------ | ------------- | ------------- |
| **Website Environments** | ✅ Full access | ✅ Full access |
| **Desktop Environments** | ✅ Full access | ✅ Full access |
| **MCP Environment**      | ✅ Full access | ✅ Full access |

<Note>
  **Verifier Access Differs:**

  * Website Environments expose `/verifier` in Docker containers
</Note>
