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

​
Path 1: Gymnasium Web UI

Best for: Researchers who want to explore environments, test agent behaviors, or demonstrate capabilities without infrastructure setup.
Access the Web UI at 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

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

​
Get Started

Docker Quick Start

Load and run environment containers with your agent loop

​
Environment Availability

All three environment types are available through both paths:
EnvironmentWeb UIDocker
Website Environments✅ Full access✅ Full access
Desktop Environments✅ Full access✅ Full access
MCP Environment✅ Full access✅ Full access
Verifier Access Differs:
  • Website Environments expose /verifier in Docker containers
