E2B provides isolated Linux machines for AI agent sessions, with infrastructure managed by E2B or deployed in a customer’s cloud. Each session runs in its own Firecracker microVM and kernel, without sharing filesystem or memory with another customer’s sandboxes. An API covers execution, networking, storage, secrets, observability, and lifecycle management. The Code Interpreter SDK runs Python or JavaScript and can return charts, tables, and images; Desktop supplies screen, mouse, keyboard, and live streaming for computer-use agents. Listed integrations include CrewAI, Agno, Mastra, OpenAI Agents SDK, Google ADK, LangChain Deep Agents, and Vercel AI SDK. E2B Cloud is available in US, EU, and APAC regions. Enterprise BYOC can place sandboxes in a customer’s AWS, Google Cloud, or Azure account. The runtime is Apache-2.0 licensed and self-hostable. Hobby is free, with a one-time $100 usage credit, sessions up to one hour, and 20 concurrent sandboxes. Pro costs $150 a month plus usage costs.
