Zep Cloud: what it remembers, who owns it, and what it costs
thecontinuitylayer.com/memory-systems/zepA managed temporal knowledge-graph context layer for agents, with per-user graphs, threads and a context API, built on the open-source Graphiti engine.
- 1Partly
Is Zep Cloud open source?
Partly, by Zep's own page.
Graphiti, the graph engine that powers Zep, is Apache-2.0; the getzep/zep repository says it is not Zep's product and that Zep Community Edition is no longer supported.
Yes means: The core is under an open-source license.
- 2Partly
Can you run Zep Cloud yourself?
Partly, by Zep's own page.
Free, Flex and Flex Plus run on Zep Cloud only; Enterprise offers deployment to your own cloud account. Otherwise self-hosting means building on Graphiti yourself.
Yes means: It runs on your own machine or server.
- 3Partly
Can you take your memory out of Zep Cloud?
Partly, by Zep's own page.
Read endpoints return the nodes, episodes and edges of a user's or group's graph; no bulk export is documented.
Yes means: An export, or the data sits in a standard store you own.
- 4Partly
Does Zep Cloud work with more than one model provider?
Partly, by Zep's own page.
Zep sits beside whichever chat model you use; the quickstart shows OpenAI and gives guidance for Anthropic and other providers. Which model Zep uses internally is not stated.
Yes means: It is not tied to one provider's models.
- 5Yes
Is there a hosted Zep Cloud?
Yes, by Zep's own page.
Zep Cloud is the product; a free tier with monthly credits is offered.
Yes means: A cloud or managed option exists.
- 6Yes
Does Zep Cloud have a free tier, and what is the entry price?
Yes, by Zep's own page.
Free at $0 with 10,000 credits a month; Flex at $125 a month; Flex Plus at $375; Enterprise custom.
Yes means: A free tier exists and the entry paid price is published.
- 7Yes
Does Zep Cloud scope memory per user and per session?
Yes, by Zep's own page.
A user can have many threads; facts learned in one session are available across all of that user's sessions, and group graphs are shared across users. The graph does not separate data by thread.
Yes means: Both per-user and per-session or per-agent memory are supported.
- 8Yes
Can you delete a user's memories from Zep Cloud?
Yes, by Zep's own page.
Deleting a user removes the user's threads, messages and graph; edges, nodes, episodes and threads can also be deleted one at a time.
Yes means: A documented way to delete everything for one user.
What these grades say about continuity, and what they do not.
Every grade on this site is read from the maker's own pages. The Continuity Framework asks five things of any system that carries state: that it carry, govern, evolve, prove and forget. These tests reach carry, govern and forget; they do not reach evolve or prove, which no maker's page documents in a gradeable way. A high letter is a good memory system, not a continuity layer.
- M1 Open sourceCarry
- Open source means the memory engine can outlive the vendor; the state is not hostage to a contract.
- M2 Self-hostCarry
- Self-hosting puts the store under the owner's control, which is the precondition for every other obligation.
- M3 ExportCarry
- An export is question C3: can the state leave in a form another system reads? A standard store you own answers it; a proprietary dump only partly.
- M4 Any modelCarry
- Working with more than one model provider is question C2: the memory, not the model, holds the state.
- M7 ScopingGovern
- Scoping per user, agent and session is question G2: who may read and write each item. It is the floor of governance, not the ceiling.
- M8 DeleteForget
- A documented delete for one user is rung 5 of the erasure ladder: the record leaves the store. Derived memories, the index and backups are not covered unless the maker says so. Rung 5 of the erasure ladder: delete the record.
