The honest brief
Cognee
Builds an LLM-derived knowledge graph alongside embeddings, so recall follows relationships, not just vector similarity.
- Self-hostable Python SDK
- Recall follows concept relationships
- Bring your own LLM/embedding provider
- Newer, smaller ecosystem
- Cognify pipeline adds LLM cost
- Self-host setup overhead
MemMachine
Pairs episodic (conversational) and profile (long-term user-fact) memory in one model-agnostic, self-hostable layer.
- Fully open source (Apache-2.0)
- Recall persists across sessions
- Model-agnostic across providers
- Self-hostable, Python-first
- Younger than Mem0/Zep
- Self-hosting and ops on you
- Managed enterprise tier not yet GA
