About
E2B (E2B.dev) is a cloud infrastructure platform purpose-built for AI agent sandboxing, providing secure, isolated execution environments where AI agents can run code, manage files, browse the web, and interact with system resources without endangering the host machine. Unlike general-purpose containers or VMs, E2B's sandboxes are designed with AI-specific requirements: millisecond-level startup times (critical for agent workflows that spawn many short-lived sessions), built-in file system APIs that agents can call programmatically, environment snapshot/restore capabilities for iterative development, and comprehensive audit logging of every action the agent takes. E2B integrates directly with popular AI frameworks like LangChain, CrewAI, and AutoGen, making it straightforward to add sandboxing to existing agent pipelines. The platform supports multiple runtimes (Python, Node.js, Bash) within each sandbox, and provides SDKs for Python and JavaScript. For teams building autonomous AI agents that need to execute untrusted code, access the internet, or manipulate files — E2B provides the security boundary that turns a risky prototype into a production-ready system. It's particularly valuable for coding agents, research agents that scrape the web, and multi-agent systems where one agent's actions shouldn't compromise others.
