E2B vs metatron
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.; metatron: Metatron is a self-hosted system that captures a codebase's real implementation decisions—preferred patterns, rejected approaches, edge cases, internal conventions—as structured data. It serves these "decisions" to coding agents via MCP, allowing them to write code like a senior engineer who deeply understands the codebase, rather than constantly rediscovering conventions.
