E2B
What it is
E2B provides isolated Linux machines for AI agent sessions, with infrastructure managed by E2B or deployed in a customer's cloud. Each session receives a full microVM and an API for code execution, networking, storage, secrets, observability, and lifecycle management. The Code Interpreter SDK runs Python or JavaScript and can return charts, tables, and images. Desktop provides a screen, mouse, keyboard, and live stream for computer-use agents. E2B lists support for frameworks and SDKs including CrewAI, Agno, Mastra, Claude Managed Agents SDK, OpenAI Agents SDK, Google ADK, LangChain Deep Agents, and Vercel AI SDK. E2B Cloud is available in US, EU, and APAC regions. Enterprise BYOC places sandboxes inside a customer's AWS, Google Cloud, or Azure account. Sandboxes use separate Firecracker microVMs and kernels without shared filesystem or memory between customers. The runtime is Apache-2.0 licensed and self-hostable. The free Hobby plan includes a one-time $100 usage credit, sessions up to one hour, and 20 concurrent sandboxes. Pro costs $150 a month plus usage costs, with sessions up to 24 hours and 100 concurrent sandboxes.
