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. 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.
