E2B
E2B (e2b-dev) provides secure, isolated cloud sandboxes for AI agents and AI-generated code, built on a forked Firecracker microVM runtime. The platform ships a REST Sandbox API, JavaScript and Python SDKs, a Code Interpreter SDK, a Desktop Sandbox for computer-use agents, persistent volumes, a custom template build system, and an e2b CLI. The Apache-2.0 licensed core repos — E2B, infra, firecracker, code-interpreter, and desktop — also support self-hosted deployments on AWS, GCP, Azure, or bare Linux. E2B is LLM-agnostic and used by labs and enterprises building code interpreters, deep-research agents, data analysis features, reinforcement-learning environments, and computer-use agents.
