Getting Started

Welcome to Modal Sandboxes. This guide will walk you through prerequisites, environment configuration, and launching your first sandbox.

What is Modal Sandboxes?

Modal Sandboxes is a cloud execution toolkit built on top of Modal. It allows you to: 1. Spin up clean, disposable Linux development environments on demand. 2. Connect securely via SSH (ssh <sandbox-name>) or web tunnels (port 3000). 3. Test applications inside isolated Linux VMs with Docker-in-Docker support. 4. Run AI coding agents (T3 Code, OpenCode, Antigravity, Pi) inside managed environments. 5. Capture snapshots of sandbox states to pause and resume work instantly.

Learning Path

  1. Prerequisites & Setup: Ensure you have Python 3.11+, Git, and a configured Modal account.
  2. Quickstart: Launch a standalone sandbox in 60 seconds with zero additional configuration.
  3. CLI Reference: Explore the command-line options available in modal-sandbox.
