Zep is agent-memory infrastructure — a temporal knowledge graph that developers build their own agents on top of, at enterprise scale. Atlaso is the memory you turn on for the AI tools you already use: Claude Code, Cursor, Codex and more, sharing one memory with no code to write. They live on different layers. Here's which one you actually need.
An honest comparison starts with credit. If you're an engineer building an agent, Zep earns a real look — so before we draw the line, here's where it's strong.
Memory that tracks time
Zep's open-source Graphiti engine models not just what's true, but when it was true — and when it changed. New facts invalidate old ones without erasing history, so an agent can ask what was true on any past date. Few systems model this as rigorously.
A graph, not just notes
It fuses conversations with business data into one queryable knowledge graph, with custom entity and relationship types. For a team modelling a complex domain inside an agent, that structure is genuinely powerful.
Built for production teams
SOC 2 Type II, HIPAA BAA, and BYOC / BYOK deployment options, on top of a widely-adopted open-source core. If you're shipping a regulated agent at scale, that groundwork matters.
Every point below is about who has to do the work — and it's the reason Zep and Atlaso aren't really the same purchase.
“Agent memory, at enterprise scale.”
You build the app
Zep is an API and SDK (Python, TypeScript, Go). A developer wires it into an application they're building — the memory only exists inside the agent you write. There's no “install Zep and your tools share memory”.
Not an end-user product
It's aimed at engineers and enterprises. You can't adopt Zep to give your existing Claude Code, Cursor, or Codex a shared memory — those aren't apps built on Zep, so Zep never reaches them.
Self-hosting is now DIY
Zep retired its self-hostable server (Community Edition) in April 2025. Owning it yourself today means running the raw Graphiti library on your own graph database and building the service around it.
Priced and sold for teams
Zep Cloud is credit-metered, with paid tiers starting around $1,250 a year and enterprise handled by sales. It's built for teams shipping agents, not for one person's personal toolchain.
Five dimensions that decide which layer you actually need.
If you're an engineer building a production agent and you need a temporal knowledge graph you control, Zep is a credible, serious choice — build on it. Atlaso is for the other job, and often the same person off the clock: you just want the AI tools you already use to stop forgetting and share one memory, without building anything. One is infrastructure; the other is a product. Plenty of people want both.
Zep details as of July 2026, from getzep.com, its pricing page, and the open-source Graphiti project.
Atlaso captures and recalls automatically, scrubs secrets on your device, and shares one memory across the tools you already work in — no code to write. Free to start, no credit card required.
