Zep Is Completely Free — Here's What You Get

⚡ Quick Verdict

Zep is completely free with 4 features included. No paid tiers offered, making it perfect for budget-conscious users.

👤

✓Temporal knowledge graph captures entity relationships and time-based context that flat vector stores completely miss
✓Handles temporal queries naturally — 'what did the user say about X last month' works out of the box
✓Automatic conversation summarization keeps context manageable without losing access to historical detail
✓Entity and relationship extraction creates structured knowledge from unstructured conversations
✓Python and TypeScript SDKs with LangChain integration provide straightforward developer experience

⚠Knowledge graph extraction is computationally expensive — adds meaningful latency and LLM cost per message
⚠Temporal knowledge graph features are primarily in the commercial cloud version, not the open-source Community Edition
⚠Graph quality depends on conversation richness — sparse or highly technical conversations produce limited graph structures
⚠More complex to operate and debug than simple vector-based memory stores like Mem0

While currently free, pricing models can change. Zep may introduce paid tiers in the future as they expand features.

Zep offers core ai memory & search features at no cost. Paid alternatives may provide more advanced functionality or premium support.

Zep may have usage limitations, reduced support, or be supported through other revenue streams. Always check the terms of service.
