akb vs Zengram

akb: AKB is an agent knowledgebase that serves organizational memory for AI agents over the Model Context Protocol (MCP). It provides hybrid semantic + keyword search, structured tables, files, and a URI graph, all backed by Git for version history. Designed as a drop-in alternative to Confluence or Notion for MCP-aware agents like Claude Code, Cursor, and Windsurf.; Zengram: Zengram is a shared memory system for multi-agent AI systems, enabling agents to store and retrieve memories across machines. It features typed memory, dual storage (Qdrant + SQLite/Postgres), multi-path search, and cross-agent capabilities like briefings and corroboration. Self-hosted, open-source, with MCP server and SDKs.
