01Overview
Zep is an enterprise agent memory layer built around a temporal knowledge graph. It extracts entities and relationships from conversations, maintains them over time, and retrieves them with temporal awareness. It markets toward enterprise scale and compliance.
AgentPrizm uses a simpler model: six explicit memory types stored and retrieved over a plain REST API and a remote MCP server, with governance primitives (confidence scores, validity windows, contradiction detection, audit receipts, right-to-forget) built in. It is designed to be easy to wire into any agent without understanding a graph model.

02Capability comparison
| Capability | AgentPrizm | Zep |
|---|---|---|
| Core model | Typed memory store: six memory types (fact, lesson, directive, preference, contact, bookmark). Flat but governed. | Temporal knowledge graph: entities, relationships, and episodes extracted and maintained over time. |
| Integration model | REST API + zero-install remote MCP server. No SDK required. Any HTTP client works. | Python and TypeScript SDKs. REST API available. Cloud and self-hosted options. |
| Retrieval approach | Hybrid semantic + keyword. Filterable by type, container, severity, date, and confidence threshold. | Graph + vector hybrid. Entity-centric retrieval — can traverse relationships between entities. |
| Fact-validity windows | First-class field on every memory. Expired memories excluded from recall automatically. | Temporal graph tracks entity state over time. Episode-based temporal context rather than per-fact expiry fields. |
| Contradiction / conflict handling | Detected on ingest. Superseded memory marked and excluded from recall; preserved in audit trail. | Knowledge graph updates entity state when new information contradicts prior episodes. |
| Audit receipts | Every recall request returns a traceable receipt — what, when, which agent. Retained per plan. | Compliance and audit features are positioned toward enterprise tiers; depth varies by tier — verify against Zep’s current docs. |
| Right-to-forget (GDPR) | One call: POST /forget with soft or hard mode. Container-wide purge supported. Audit event preserved. | User and entity deletion endpoints exist. Compliance tooling aimed at enterprise buyers. |
| Container / namespace scoping | Containers are a first-class concept. Per-user, per-repo, per-project isolation with named containers. | User and session-level memory scoping. Graph supports multiple users. |
| Complexity to operate | Hosted service — zero ops. Add URL + API key; the memory layer is live. | Cloud (hosted) and self-hosted options. Self-hosted requires running a graph database (Neo4j or similar) in addition to application services. |
| Learning curve | Six memory types, REST endpoints. Most teams are recalling memories within a day of starting. | Graph model has a steeper conceptual ramp — understanding entities, episodes, and relationships takes time. |
| Transparent pricing | Hobby $0/forever. Builder $29/mo. Scale $249/mo + usage. Listed publicly at agentprizm.com/pricing. | At the time of writing, not all tier prices are publicly listed — check getzep.com for current pricing and contact their sales team for enterprise quotes. |
| Open source | Closed source hosted service. Free tier with no card required. | Community edition is open source. Cloud and enterprise are proprietary. |

03When to choose AgentPrizm
- You want a simple typed-memory model — your agent needs to store and recall facts, lessons, and directives without modeling a knowledge graph.
- You want to be live in under a day: add URL + key, zero ops, no database to run.
- You need transparent pricing that does not require a sales call to evaluate.
- You want GDPR right-to-forget as a single API call, not a project.
- You prefer REST + remote MCP over an SDK-first integration.
- Your governance needs are validity windows, audit receipts, and contradiction handling — not a full temporal knowledge graph.
04When to choose Zep
- Your agent needs to traverse relationships between entities — graph-native reasoning (who reports to whom, which accounts are related, etc.).
- You are building enterprise conversational AI and need graph-backed entity memory across many sessions and users.
- Your team already has experience with knowledge graphs and the graph model is a feature, not a burden.
- You need the compliance and enterprise support tier that Zep offers to its largest customers.
The best way to compare memory layers is to run both against your actual agent workload. AgentPrizm's Hobby tier is free — no credit card, 1,000 memories, and the full governance feature set. Wire it up alongside your current approach and measure the difference.
05Frequently asked questions
Is AgentPrizm a Zep alternative?
Yes. AgentPrizm is a simpler, more transparent alternative to Zep for teams that need governed agent memory without the complexity of a temporal knowledge graph. AgentPrizm uses six explicit memory types over a REST API and remote MCP server, with built-in validity windows, audit receipts, and one-call right-to-forget. Zep's strength is graph-native entity memory for complex relational use cases; AgentPrizm's strength is fast onboarding, transparent pricing, and plain REST + MCP with governance primitives built in.
When should I choose Zep over AgentPrizm?
Choose Zep when your agent needs to reason about relationships between entities — for example, an agent that needs to understand that a contact reports to a decision-maker, that two accounts share a parent company, or that a set of episodes are causally related. Zep's knowledge graph is designed for that relational traversal. AgentPrizm is better suited for agents that need to store and recall flat typed memories about entities (facts, lessons, directives) without graph traversal.
Does AgentPrizm have compliance features like Zep?
AgentPrizm includes an audit receipt on every recall request, contradiction detection, fact-validity windows, and a one-call GDPR right-to-forget across all paid plans. It is not SOC 2 or HIPAA certified (see agentprizm.com/security for the honest current posture). Zep markets to enterprise buyers and offers compliance tooling at the enterprise tier. If SOC 2 or a BAA is a procurement requirement, check each provider's current certification status.
How does AgentPrizm pricing compare to Zep?
AgentPrizm publishes pricing transparently: Hobby $0/forever, Builder $29/mo, Scale $249/mo + usage. At the time of writing, Zep does not publicly list all tier prices — check getzep.com for current pricing and contact their team for a quote. AgentPrizm's free tier requires no credit card and includes hybrid recall, container scoping, and audit receipts.
