E2B is an open-source tool for running AI-generated code in secure, isolated sandboxes in the cloud. Agents can use these sandboxes, built on top of Firecracker microVMs, to safely execute code, analyze data, conduct research or operate a virtual machine. This enables you to build and deploy enterprise-grade AI agents with full control and security over the execution environment.
