E2B provides on-demand, isolated cloud sandboxes purpose-built for AI agents to safely execute code, run terminal commands, browse the web, and manage files. Built on Firecracker microVM technology, sandboxes launch in under 200ms and support any Linux-compatible language or framework. E2B is used by AI coding agents, code interpreter features, and autonomous agent pipelines that need to execute untrusted or AI-generated code without exposing host infrastructure. Key features: - Firecracker microVM isolation with sub-200ms cold start - Supports any language or framework running on Linux (Python, JS, Ruby, C++, etc.) - Sandbox sessions up to 24 hours (Pro plan) - E2B Desktop sandboxes for AI agents controlling virtual Linux desktops - Up to 1,100 concurrent sandboxes on Pro with add-ons - Full internet access, file management, and terminal within sandboxes
