Balanced 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.
