E2B vs kdcube

E2B: E2B is an open-source infrastructure that enables running AI-generated code securely in isolated cloud sandboxes. It provides JavaScript and Python SDKs to start and control these sandboxes for AI applications.; kdcube: KDCube is an open-source, self-hosted production runtime designed for AI applications and agents, providing the necessary infrastructure to run frameworks like LangGraph, CrewAI, or custom agents in production. It handles multi-user serving, ordered conversation delivery, streaming, isolated code execution, cost controls, and secure deployment from Git, allowing developers to focus on agent logic rather than operational complexities.
