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
Papr
Predictive memory graph that surfaces anticipated context to agents, rather than only returning similarity-matched chunks like a vector store.
- Open-source AGPL-3.0 core
- TypeScript and Python SDKs
- Managed cloud or self-hostable
- Automatic chat-memory compression
- Newer, smaller ecosystem
- Memory-only scope
- AGPL may deter some commercial use
