# Make Your Agent's Memory Portable: Export, Own, and Re-Import With mem0

> A code-forward walkthrough for getting every memory out as structured JSON you control — add, get_all, re-import — so no vendor's shutdown can delete your users' context.

## Key takeaways

- Portability is a day-one architecture decision, not a migration you scramble through in a crisis.
- Put your memory access behind a thin interface with add/all/snapshot, and the backend becomes a swappable detail instead of a lock-in.
- With the open-source mem0 Memory() class you self-host the store, and get_all(user_id=...) dumps every memory to JSON you own.
- Re-importing that JSON into a fresh store with infer=False proves the round-trip is real and provider-independent.
- Snapshot on a schedule to storage you control — your own Postgres or S3 — so a vendor's forced deletion is an inconvenience, not a catastrophe.

## At a glance

| Aspect | mem0 | Zep | Letta |
| --- | --- | --- | --- |
| Architecture | Extract-and-store memory layer over a vector store | Temporal knowledge graph (Graphiti) | OS-style editable memory blocks |
| Storage you can self-host | Qdrant, pgvector, others via config | Neo4j, FalkorDB, Kuzu | Postgres + optional git-backed MemFS |
| Export path | get_all(user_id) to JSON (OSS); create_memory_export (hosted) | Query graph nodes + edges | blocks.list()/blocks.retrieve() |
| License | Apache-2.0 | Apache-2.0 (Graphiti) | Apache-2.0 |
| Unit of memory | A fact string + metadata | A typed, time-bounded edge | A labeled block of text |
| Best for | Fast portable key-value-ish memories | Facts that change over time | Agents that edit their own memory |

## By the numbers

- **3 calls** — add, get_all, re-add = a portable round-trip
- **60K+** — mem0 GitHub stars
- **v2.0.12** — mem0ai version verified (Jul 13 2026)
- **7 days** — how fast a hosted mem0 export expires
- **Oct 15 2026** — day Doubao's deleted agent data becomes unrecoverable

**The short version:** Portability is an architecture decision you make on day one, not a migration you do in a crisis. Put your memory behind a thin `add`/`all`/`snapshot` interface, self-host the store, and periodically dump every memory to structured JSON you own. Three calls prove it works: `add`, `get_all`, and re-`add` into a fresh backend.
On July 15, 2026, ByteDance's Doubao and Alibaba's Qwen switch off their companion agents to comply with China's new anthropomorphic-interaction rules — [the largest forced deletion of agent memory in history](/posts/china-persona-shutdown-agent-memory-ownership-gap.html). Millions of agents' accumulated context evaporates, and for Qwen there is no export button at all. That is the whole argument for this piece: if you build on a managed memory layer, you must be able to get every memory out as structured data before someone else decides you can't.
Why memory is the risky dependency
RAG re-fetches documents on every turn; [agent memory](/topics/agent-memory) *accumulates* — it's the one asset that grows more valuable and more irreplaceable the longer your product runs. (If that distinction is fuzzy, see [agent memory vs RAG](/posts/agent-memory-vs-rag.html).) You can rebuild an index from source files. You cannot rebuild three years of a user's preferences, corrections, and history from nothing. So the memory layer is exactly the dependency you least want to be unable to leave.
> You can re-index documents any day of the week. You cannot re-derive a user's accumulated context — which is why the memory layer is the one place lock-in actually hurts.

The worked example: mem0, self-hosted
[mem0](https://github.com/mem0ai/mem0) is the most-adopted open-source memory layer (60K+ stars, Apache-2.0). The key move is choosing the open-source `Memory()` class over the hosted `MemoryClient()`, because `Memory()` runs against vector stores and LLMs *you* configure.
```
pip install mem0ai   # v2.0.12, verified Jul 13 2026
```
1. Add memories
```
from mem0 import Memory

m = Memory()  # self-hosted: vectors + metadata live in your store

m.add(
    [{"role": "user", "content": "I'm vegetarian and allergic to peanuts."}],
    user_id="rosa",
)
m.add("Prefers morning standups.", user_id="rosa")
```
`add()` returns a dict with a `"results"` key describing what was extracted. To keep the store in infrastructure you operate, build it from config instead:
```
config = {
    "vector_store": {"provider": "pgvector",
                     "config": {"connection_string": "postgresql://..."}},
    "llm": {"provider": "openai", "config": {"model": "gpt-4o-mini"}},
}
m = Memory.from_config(config)
```
Now the data sits in *your* Postgres. (For the tradeoffs of vector vs. filesystem stores, see [filesystem vs vector database for agent memory](/posts/filesystem-vs-vector-database-agent-memory.html).)
2. Export everything to JSON you own
This is the payoff. `get_all()` does a raw retrieval — no ranking, no [semantic search](/topics/rag-retrieval) — of every memory for a scope:
```
import json

dump = m.get_all(user_id="rosa")   # -> {"results": [ ... ]}
memories = dump["results"]         # each: id, memory, metadata, created_at

with open("rosa-memories.json", "w") as f:
    json.dump(memories, f, indent=2, default=str)

print(f"Exported {len(memories)} memories you now own.")
```
Note the shape: current mem0 wraps results in a `"results"` key (older 1.0-style responses returned a bare list, so normalize if you pin an old version). Each item carries `id`, the extracted `memory` text, `metadata`, and `created_at`. That JSON is now yours — commit it, ship it to S3, back it up. The hosted platform's `create_memory_export()`/`get_memory_export()` also exists, but those exports **expire after 7 days**, which tells you exactly how much the vendor expects you to keep.
3. Re-import into a fresh store to prove portability
Portability isn't real until you've reversed it. Stand up a brand-new backend and replay the JSON:
```
fresh = Memory()  # different backend, same interface

with open("rosa-memories.json") as f:
    memories = json.load(f)

for item in memories:
    fresh.add(
        item["memory"],
        user_id="rosa",
        metadata=item.get("metadata") or {},
        infer=False,   # store verbatim; don't re-extract
    )
```
`infer=False` writes each memory as-is instead of running LLM fact-extraction again, so you get a faithful copy rather than a re-interpretation. The round-trip — `add` → `get_all` → `add` — is the entire proof that no single vendor holds your context hostage.
4. The thin interface that makes the backend swappable
Do steps 1–3 through a protocol, and mem0 becomes an implementation detail:
```
from typing import Protocol

class MemoryStore(Protocol):
    def add(self, text: str, user_id: str, metadata: dict | None = None) -> None: ...
    def all(self, user_id: str) -> list[dict]: ...
    def snapshot(self, user_id: str) -> list[dict]: ...
```
```
class Mem0Store:
    def __init__(self, config: dict | None = None):
        self._m = Memory.from_config(config) if config else Memory()

    def add(self, text, user_id, metadata=None):
        self._m.add(text, user_id=user_id, metadata=metadata or {})

    def all(self, user_id):
        return self._m.get_all(user_id=user_id)["results"]

    def snapshot(self, user_id):
        rows = self.all(user_id)
        # write rows to storage YOU control: Postgres, S3, a file
        return rows
```
Swap in a `ZepStore` or `LettaStore` later and nothing above the interface changes.
The same principle in Zep and Letta
[Zep's](https://github.com/getzep/graphiti) open-source Graphiti engine keeps a *temporal knowledge graph* in your own Neo4j, FalkorDB, or Kuzu instance; each edge is a typed fact with a `valid_from`/`valid_until` window, so your export is graph nodes and edges rather than flat strings. [Letta](https://docs.letta.com/guides/core-concepts/memory/memory-blocks) (Apache-2.0, self-hostable via Docker) models memory as editable OS-style blocks labeled `human`, `persona`, and so on; you read them straight out with `client.agents.blocks.list(agent_id=...)` or `client.agents.blocks.retrieve(agent_id=..., block_label="human").value`. Different shapes, same requirement: a self-hostable store and a documented read-out path. For a fuller comparison, see [mem0 vs Zep vs Letta](/posts/mem0-vs-zep-vs-letta-agent-memory.html) and [the three places to keep an agent's memory](/posts/three-places-to-keep-an-agents-memory.html).
Day one, not crisis day
The two-part rule that survives any vendor decision: **(1)** access memory only through a thin interface so the backend is swappable, and **(2)** run a scheduled `snapshot()` that writes structured JSON to storage you control. Do both on the first day and a forced shutdown is a re-import job, not a wake. The teams whose agents went dark this week didn't lack a migration plan — they lacked an export they'd already run. Don't be them.

## FAQ

### How do I export all memories from mem0?

Use the open-source Memory() class and call get_all(user_id=...), which returns a dict with a 'results' list where each item has id, memory (the extracted text), metadata, and created_at. Serialize that list to JSON and you have a structured copy you own. The hosted MemoryClient also has create_memory_export()/get_memory_export(), but those are platform-only and exports expire after 7 days.

### Does self-hosting mem0 keep my data?

Yes. Memory() (and Memory.from_config()) runs against vector stores and LLMs you configure — Qdrant, pgvector, and others — so the vectors and metadata live in infrastructure you operate, not on someone's SaaS. mem0 is Apache-2.0.

### How are Zep and Letta different for portability?

Zep's open-source engine Graphiti stores a temporal knowledge graph in your own Neo4j/FalkorDB/Kuzu, so you export graph nodes and edges (each edge carries valid_from/valid_until). Letta is Apache-2.0 and self-hostable, and exposes OS-style memory blocks you read out with client.agents.blocks.list(agent_id=...).

### What's the minimum portable-memory setup?

A thin interface (add/all/snapshot) in front of whatever backend you use, plus a scheduled job that calls all() and writes the JSON to storage you control. That's it — the interface makes swapping cheap, the snapshot makes deletion survivable.
