Zep
Memory and context service for AI agents that stores conversations and business data in a temporal graph.
How the 6.8 was reached
- Quality of output7/10
Independent comparison shows 63.8% on LongMemEval versus Mem0's 49.0%; P95 latency about 300ms exceeds vendor's 200ms claim. atlan.com
- Ease of use7/10
Vendor says three lines of code and sign-up via GitHub, Google or Microsoft; no independent usability evidence. app.getzep.com
- Pricing value6/10
Free tier of 10,000 credits; paid from $125/month with overage charges that make usage cost harder to predict. getzep.com
- API and integration quality7/10
Memory, retrieval and storage with webhooks, custom entity types and an MCP server; no SDK language list was found. getzep.com
- Solves the problem it claims to solve7/10
S&P Global Market Intelligence validated its temporal graph approach to agent memory, and it is SOC 2 compliant; the headline claim is broader than memory. atlan.com

Pros & Cons
Pros
- An independent comparison shows 63.8% on LongMemEval versus Mem0's 49.0%
- S&P Global Market Intelligence validated its temporal graph approach
- SOC 2 compliant, with access policies for what each agent can retrieve
- Free tier and quick start with three lines of code, per Zep
Cons
- P95 latency was about 300ms in an independent check, above the 200ms vendor claim
- Credit overages make monthly cost harder to predict
- No SDK language list was found
- The headline claim is broader than the memory use case
Zep suits teams building agents that need long-running memory and governed access to business data. Teams with tight latency budgets or fixed costs should test real usage first, since latency ran above the vendor figure and credits can overrun.
