Zep alternative
MemexAI vs Zep for self-hosted AI memory.
Zep is a strong fit when you want graph-oriented conversation memory and temporal relationships. MemexAI is the simpler path when your product needs inspectable user memory files, revision history, access logs, and a Postgres-native deployment.
Core difference
Zep is graph-oriented memory. MemexAI is an inspectable memory workspace.
MemexAI
Run the service with Docker or use direct Postgres mode. Memory lives as scoped files that agents and humans can both read.
Zep
Zep's paper frames Graphiti as a temporally-aware knowledge graph that synthesizes conversational and business data while maintaining historical relationships.
Technical tradeoff
Graphs help when relationships are the product. Files help when the record must be obvious.

Zep
What is the unit of memory?
A scoped file under user/ or shared/
Entities, relationships, episodes, and graph facts
What is the strength?
Human-legible state and simple self-hosting
Temporal relationship modeling and graph retrieval
What is the risk?
Files need curation and naming hygiene
Graph memory can add operational and debugging complexity
Best fit
Product memory, policies, preferences, correction records

When to choose MemexAI
Choose MemexAI when the memory record needs to be simple enough for your team to debug.
Every write creates a revision you can inspect later.
The admin UI shows memory files, revisions, and access logs.
Your AI product can use TypeScript, Python, REST, or MCP against the same service.
Source note
Zep and MemexAI optimize for different operating models.
Zep's public technical story is graph memory. MemexAI's story is memory that can be opened like a file, corrected like product data, and audited through revisions and access logs.
