Zep is a closed-source, managed memory platform for AI agents built around a temporal knowledge graph — it tracks how facts and conversations change over time and offers sub-200ms retrieval, sold as a hosted service (with a VPC deployment option for enterprise). Because it's proprietary, most teams access it through Zep's managed cloud rather than running the engine themselves.
Mem0 and Supermemory are both open-source memory layers for AI agents that you can self-host instead of depending on Zep's managed service.
FAQ
Is there a free, open-source alternative to Zep?
Yes. Mem0 (Apache-2.0) and Supermemory (MIT) are both open source and free to self-host.
What's the best open-source alternative to Zep?
Mem0 is the better pick for general-purpose multi-signal memory retrieval with temporal reasoning. Supermemory is the better pick if sub-100ms retrieval latency and an ontology-aware graph structure matter most for your use case.
