Sandbox

Sandbox refers to developer tools that provide isolated environments for running code securely. Two prominent tools sharing this name are E2B and CodeSandbox. E2B offers secure, isolated sandboxes using Firecracker microVMs designed for AI-generated applications, supporting any language or framework with runtime package installation and sessions lasting up to 24 hours on its Pro plan. CodeSandbox provides instant cloud development environments that allow developers and teams to code, collaborate, and deploy projects from any device, managing millions of concurrent virtual machines to safely execute untrusted code. Both tools target developers needing secure and scalable environments for code execution. E2B focuses on AI agent development with SDKs for Python and JavaScript, while CodeSandbox emphasizes cloud IDE capabilities with APIs for sandbox provisioning and parallel environment management.

Real-World Use Cases

AI Agent Development

Developers building AI applications can use E2B's secure sandboxes to run and test code safely with support for multiple languages and long session times.

Cloud-Based Collaborative Coding

Teams and educators can leverage CodeSandbox to create instant cloud environments for coding, collaboration, and project deployment from any device.

Quick Start
1
Install SDK
For E2B, install the SDK using package managers like pip (pip install e2b-code-interpreter) or npm (npm install @e2b/code-interpreter).
2
Create Sandbox
Use the SDK to create a sandbox instance, for example: with Sandbox() as sandbox:.
3
Run Code
Execute code within the sandbox using methods like sandbox.run_code("x=1").
4
Access Output
Retrieve execution results, for example: print(execution.text).

Assessment
Strengths
  • Provides full isolation for running untrusted code securely.
  • Supports any programming language and framework with runtime package installation.
  • E2B offers long sandbox sessions up to 24 hours on Pro plan.
  • CodeSandbox enables instant cloud development environments accessible from any device.
  • Scales to millions of concurrent virtual machines for safe code execution (CodeSandbox).
Limitations
  • 24-hour sandbox sessions are limited to the Pro plan in E2B.
  • Requires SDK setup for E2B usage.
  • CodeSandbox relies entirely on cloud infrastructure, which may add complexity in VM management at scale.
