Agentic Index

Cognee vs Zep (2026)

Cognee and Zep both bet that agent memory should be a graph, packaged differently: Cognee is open source first, free to self host, with a free cloud tier of a million tokens and Cloud Pro at two dollars fifty per million tokens, while Zep pairs its open source Graphiti engine with a hosted service from a free thousand credits a month through Flex at 125 dollars (104 annual) and Flex Plus at 375 dollars, graph included at every tier. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.

Cognee's pure token pricing suits ingestion heavy workloads; Zep's credit tiers with a production hosted service suit teams that want a managed temporal knowledge graph now.

On the Agentic Index agent infrastructure ranking, neither Cognee nor Zep clears the bar, which asks for all five production contract capabilities documented in full. Cognee documents two of the five in full; Zep does not document testing, debugging and optimization in full, nor observability and auditability. 34 of the 186 vendors in the lane clear it.
