The honest brief
mem0
Fastest path to agent memory — extracts distilled facts with a tiny token footprint and the biggest community.
- Quick to adopt, broad framework integrations
- Stores distilled facts, small footprint
- Vector + graph + key-value storage
- Open-source with usable free tier
- Weaker on temporal/state-change queries
- LLM call on every write adds latency
- Test deletion/conflict handling for regulated use
- More library than full memory server
memU
Stores memories as a hierarchical file system rather than only vector embeddings, cutting context tokens roughly 10x for always-on agents.
- Built for proactive, always-on agents
- Semantic recall via vector indexing
- Self-host or hosted cloud API
- Multimodal memory ingestion
- Younger project, evolving API
- Smaller ecosystem than vector DBs
- Hosted pricing details limited
