3 tools · the Catch, not a ranking
- Mem0Memory infrastructure for AI agents that actually persists
External dependency for a core capability. Async processing adds latency. Platform optimizations are not in the open-source SDK. You are trusting Mem0 with potentially sensitive user data.
- LettaEpisodic memory for agents that think across sessions
More complex to reason about than simple vector retrieval. The paging mechanism adds latency and orchestration overhead. Documentation assumes understanding of the original MemGPT paper.
- GraphitiApache-2.0 temporal knowledge graphs for agent memory; Zep's OSS engine
Framework only — you run a graph DB + ops. Zep Community Edition deprecated; full Zep SaaS is separate (Free credits then Flex ~$104/mo billed annually). Not a drop-in chat history store. Schema/ops cost vs Mem0 Docker.
