Zep is a memory layer for Python/TypeScript developers building LLM applications. retainr is for automation builders — n8n, Make.com, and Zapier users who need persistent AI memory without deploying infrastructure or writing code.
| Feature | retainr | Zep |
|---|---|---|
| Setup time | 30 seconds | Hours (SDK + config) |
| Code required | No | Yes (Python or TS) |
| n8n node | ✓ Community node | ✗ No native node |
| Make.com module | ✓ HTTP module | ✗ No native module |
| Zapier action | ✓ HTTP action | ✗ No native action |
| Semantic search | ✓ pgvector | ✓ Vector search |
| Managed cloud | ✓ EU (Hetzner) | ✓ US cloud |
| Self-hosted | Via API | ✓ Open source option |
| Free plan | ✓ 1,000 ops/mo | Limited |
| Target user | No-code builders | Developers |
Already using Zep in a Python or TypeScript app and want to expose memory to n8n or Make.com workflows? retainr accepts the same plain text content Zep stores, accessible via a simple HTTP API.
Use the Zep REST API to retrieve memories for each session. Export the fact or message content as plain text.
POST each memory to https://api.retainr.dev/v1/memories with a namespace (e.g. user:alice) matching your user identifier. No format conversion needed.
In n8n, install the retainr community node. In Make.com or Zapier, replace the Zep HTTP calls with retainr equivalents. The API surface is simpler.
