Best alternatives to Zep in 2026
Most ways of giving an AI agent memory boil down to searching for 'similar' past messages, which misses how facts actually relate to each other and change over time — a user's favorite restaurant six months ago isn't necessarily their favorite now. Zep takes a different approach, building what it calls a temporal knowledge graph: a structured map of facts and how they connect and evolve, so an agent can retrieve precisely relevant, up-to-date context instead of a pile of loosely similar text snippets. Zep is an enterprise-focused AI agent memory platform built around temporal context graphs, founded in 2023 by Daniel Chalef and Tyler Gillson and backed by Y Combinator, Root Ventures and Engineering Capital. It claims sub-200ms context retrieval at scale via its 'Context Lake' architecture, which manages millions of context graphs for enterprise customers, and is SOC 2 Type II and HIPAA BAA certified — compliance credentials aimed squarely at regulated-industry buyers. Pricing runs Free (10,000 credits/month, 2 projects), Flex ($104/month billed annually, 50,000 credits, 5 projects), Flex Plus ($312/month billed annually, 200,000 credits, 10 projects), and Enterprise with custom credits, SLA and unlimited projects.
