E2B: Isolated MicroVM Sandboxes for AI Agents

E2B is an infrastructure platform that gives each AI agent session its own isolated Firecracker microVM sandbox, so agents can safely execute code, run shell commands, browse the web, control a desktop, and access the filesystem. It's built for developers and AI teams building coding agents, data analysis, computer-use, agent evals, and reinforcement-learning workloads, and runs in E2B's cloud or inside your own AWS/GCP account via BYOC. Its main differentiator is a full, LLM-agnostic machine per agent session that boots in milliseconds from a snapshot, controlled through Python/JavaScript SDKs.
