cuba-memorys vs Octopoda-OS

cuba-memorys: Cuba-Memorys is a Model Context Protocol (MCP) server that gives AI coding assistants long-term persistent memory. It uses a knowledge graph, neuroscience-inspired algorithms like FSRS-6 adaptive decay, Hebbian learning, and dual-strength memory, along with anti-hallucination grounding. The latest version 2.0.0 is a complete Rust rewrite with 12 tools and sub-millisecond performance.; Octopoda-OS: Octopoda is an open-source memory OS for AI agents that provides persistent memory, loop detection, audit trails, and real-time observability out of the box. It works automatically when you create an agent, and supports both local (SQLite) and cloud (PostgreSQL) storage. It integrates with popular frameworks like LangChain, CrewAI, AutoGen, and OpenAI Agents SDK, and offers an MCP server for Claude/Cursor.
