What is E2B?

E2B provides secure, sandboxed cloud environments where AI agents can execute code safely. Each sandbox is an isolated micro-VM that boots in ~150ms, giving your AI a full Linux environment with a filesystem, terminal, and network access. Agents can write and run code in any language, install packages, manipulate files, and interact with APIs — all without risking your production infrastructure. E2B integrates with OpenAI's Code Interpreter, LangChain, CrewAI, and any framework that needs code execution. Used by AI companies building coding assistants, data analysis agents, and any application where LLMs need to execute code as part of their workflow.
