Zep — Agent Memory Platform
Zep treats agent memory as a temporal knowledge graph: facts have timestamps, provenance, and invalidation rules. Its Graphiti engine lets an agent answer 'what was true as of March 1?' rather than only 'what do I believe now?' — which matters for audit, regulated industries, and long-lived assistants. Dual-licensed OSS + managed cloud.

Frequently asked questions
What's Graphiti?
Graphiti is Zep's open-source temporal knowledge-graph engine. It ingests conversation events, extracts entities and relationships, and tracks how each fact's validity changes over time — supporting 'as-of' queries.
Zep vs. mem0?
Both solve agent memory. mem0 emphasizes simplicity and ease of integration. Zep emphasizes temporal correctness and graph-native reasoning — better for use cases where facts change and audit matters.
Is Zep open source?
Zep's core (Graphiti) is open source. The Zep cloud platform adds hosting, scaling, observability, and enterprise features on top. Both options share the same API surface.
