[::] Agentic Stacks

Cognee vs mem0

Pick two tools from the same category to compare side-by-side.

Cognee
Open-source memory platform that gives AI agents persistent long-term memory via combined knowledge graphs and vector embeddings.
mem0
Per-user long-term memory layer for agents with fact extraction.
Category memorymemory
Vendor type hybridhybrid

Strengths
  • + Combines graph and vector storage for relationship-aware retrieval beyond similarity search
  • + Provenance tracking on ingested context from files, APIs, and databases
  • + First-party integrations with agent tooling (Claude Code, LangGraph, MCP server)
  • + Pluggable backends for graph, vector, and relational storage
  • + Per-user fact extraction out of the box
  • + Managed and self-hostable
  • + Simple API surface
Tradeoffs
  • − LLM-driven graph construction adds cost and latency to the ingestion pipeline
  • − Younger project with a fast-moving API surface compared to mature retrieval stores
  • − Graph-plus-vector architecture introduces more moving parts than a plain vector memory
  • − Opinionated extraction may not fit all domains
