Overview of CodeSandbox

CodeSandbox: Your Instant Cloud Development Environment

What is CodeSandbox? CodeSandbox is a cloud development platform that allows developers to code, collaborate, and ship projects quickly from any device. Recently, CodeSandbox joined Together AI to launch CodeSandbox SDK, bringing code interpretation to generative AI.

Key Features and Benefits

  • Secure Code Generation at Scale: Use powerful APIs to create isolated development environments (sandboxes) that can run any type of code securely.
  • Secure & Isolated: Every environment runs in isolation, ensuring untrusted code doesn't affect the system.
  • Ready for Scale: Handles millions of concurrent VMs, making it easy to provision, manage, and decommission VMs.
  • Continuous Context: Resume development within the same sandbox after periods of inactivity without data loss.
  • Quick Start & Auto Resume: MicroVM infrastructure allows spinning up entire VMs, cloning them, and restoring snapshots within 2 seconds.
  • Customizable Hibernation: Gain total control over periods of inactivity before auto-hibernation.

Use Cases

  • AI Agents: Resolve user prompts or create autonomous agents running on sandboxes. Run multiple agents in parallel or A/B test different agents using the forking mechanism.
  • Development Environments at Scale: Create sandboxes for each developer or student to run code in parallel without interference.
  • Secure Code Interpretation & Evals: Interpret untrusted code safely and run popular evals on any piece of code.
  • CI/CD: Run tests inside a sandbox and hibernate it when done, allowing quick restarts for re-evaluation or further testing.

How does CodeSandbox work?

CodeSandbox leverages microVM infrastructure to provide isolated and scalable environments. It uses APIs to create and manage these sandboxes, ensuring secure code execution and continuous development context.

Template Universe
