E2B vs agent-shadow-brain
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.; agent-shadow-brain: Shadow Brain is the first open-source shared memory and context system for AI coding agents. It allows multiple agents and sub-agents to share a common brain, with features like causal memory chains, dream engine, reputation ledger, and more. It works with 10+ agents and is free and local-first.
