Zep is agent-memory infrastructure that developers build their own agents on, and Atlaso is the memory you turn on for the tools you already use: they live on different layers, so the honest question is which layer you 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 is strong.
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.
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.
Zep lists SOC 2 Type II, a HIPAA BAA, and BYOC or 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 is the reason Zep and Atlaso aren't really the same purchase.
Agent memory, at enterprise scale.
Zep is an API and SDK (Python, TypeScript, Go). A developer wires it into an application they're building, so the memory only exists inside the agent you write. There's no “install Zep and your tools share memory”.
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.
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.
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 whether you need infrastructure to build on or a product to turn on.
| Dimension | Zep | Atlaso |
|---|---|---|
| Who it's for | Developers and enterprises building their own AI agents. | Anyone who uses AI tools and wants them to share one memory, with no coding required. |
| What you adopt | An API and SDK you build an application on top of. | A finished product you install, then connect the tools you already use. |
| Setup | Write code against the SDK, design a graph schema, run and operate it in your backend. | One install command, pick your tools, done in minutes. |
| Reach | Memory inside the single app you build with it. | One shared memory across Claude Code, Cursor, Codex, Claude Desktop, OpenCode and Antigravity. |
| Pricing | Credit-metered cloud from about $1,250/year; enterprise via sales. | Free to start; Pro is a flat $10/month. |
If you're an engineer building a production agent and you need a temporal knowledge graph you control, Zep is a credible, serious choice, so 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, and plenty of people want both.
Zep details as of July 2026, from getzep.com, its pricing page, and the open-source Graphiti project.
Zep is agent-memory infrastructure: an API and SDK developers build their own AI applications on. Atlaso is a finished product: one install command gives the AI tools you already use, Claude Code, Cursor, Codex and more, one shared memory. One is a building block; the other you just turn on.
