what is sandbox-sdk fr?

Sandbox SDK is a TypeScript library that lets a developer write one piece of code to spin up an isolated, disposable environment for running commands, and then run that same code against several different backend providers without changing it. A sandbox in this context is a temporary, contained space where code can execute safely, separate from the developer's main machine or production systems. This is often used by AI coding agents that need somewhere to run and test code they generate. The supported providers include a Local option that runs on something called an AgentOS VM (useful for development, testing, and self-hosting), plus hosted options from E2B, Daytona, Vercel Sandbox, and Upstash Box, each suited to different situations such as short coding-agent jobs, persistent cloud workspaces, or long-lived serverless state. Switching between them is meant to be a matter of changing which provider you pass in, not rewriting your code. Installation is done through the Bun package manager, and the library supports Node.js versions 22 and 24 as well as Bun 1.3 and newer. The quickstart example shows creating a sandbox and running a simple command inside it, using a syntax that automatically shuts the sandbox down once it is no longer needed, even if an error occurs. On Node.js 22, developers need to either compile their TypeScript differently or use an alternate helper function to get the same automatic cleanup behavior. Full setup instructions, usage guides, integration details, and API reference documentation are hosted on the project's own documentation site rather than in the README itself. The project is released under the MIT license and maintained by OpenCore.
