## Documentation

# Deploy and Host self hosted Mem0 vs Supermemory (Open-Source AI Memory Layer Compared with Supermemory) on Railway

This template runs the open-source Mem0 REST server with a dashboard and Postgres 18 plus pgvector, so you keep memories in your own database.

## About Hosting Mem0 vs Supermemory open-source software on Railway (self hosted Mem0 as a Supermemory alternative template)

Mem0 is an Apache-2.0 memory layer, and this template runs its REST server in your own Railway project.

The stack has four services.

## Why Deploy Mem0 vs Supermemory, the Supermemory alternative on Railway (Railway Free Trial)

Supermemory is a hosted memory API, so you skip running a database but send every stored conversation to their servers.

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying Mem0 vs Supermemory on Railway, you are one step closer to supporting a complete full-stack application with minimal burden. Host your servers, databases, AI agents, and more on Railway.

### Railway vs Other Hosting Providers and VPS for Mem0 vs Supermemory self hosting

Self hosting Mem0 means you choose where your Postgres and pgvector data lives.

| Provider | What You Get with Railway | What You Get with the Other Provider |
| --- | --- | --- |
| DigitalOcean | Four services from one template, with Postgres 18 and pgvector set up for you. | A Droplet and Managed Postgres, but you install pgvector and handle TLS and updates. |
| AWS | Fast setup with per-service logs and private networking, without touching VPCs. | Deep control over RDS and VPC, which helps at scale but adds setup for one memory API. |
| Hetzner | Managed Postgres and the dashboard in one project, with no server patching. | Lower raw cost per GB of RAM, if you run the Docker Compose stack and backups yourself. |

Pick Railway for a stack running in minutes, and a VPS for cheaper hardware and more ops work.

## Common Use Cases for hosted Mem0 vs Supermemory

- **Per-user memory for a support chatbot:** Each customer gets a `user_id`, so the bot recalls past tickets and preferences on the next conversation without you building extraction logic yourself.
- **Agent memory that must stay in your own database:** If your agents hold customer context you can't send elsewhere, Mem0 keeps the vectors in your Postgres with pgvector and the history log on its own volume.
- **Comparing extraction quality on the same transcripts:** Run identical conversations through Mem0 and Supermemory and compare which facts each one keeps, which is the fastest way to choose between them for your domain.
- **Avoiding a second vendor for regulated data:** If compliance rules limit which third parties can handle personal data, one self-hosted service plus your own LLM key means fewer vendors to review, though the LLM provider still sees the messages.
- **A memory API shared by several apps:** Issue a separate API key per app under API Keys, and have each app read and write memories for the same users through one endpoint.

## Dependencies for Mem0 vs Supermemory Docker hosted on Railway

This template runs four services on Railway: a Caddy proxy as the only public entry point, the FastAPI memory server, the Next.js dashboard, and Postgres 18 with pgvector.

### Deployment Dependencies for Managed Mem0 vs Supermemory Service (AI Memory)

- **mem0 (Caddy 2.11.7 proxy):** the only public service, on port 8080 with health at /healthz. It routes API paths to mem0-api and everything else to the dashboard.
- **mem0-api (FastAPI):** private on port 8000, with a /app/history volume for the SQLite history log.
- **mem0-dashboard (Next.js):** private on port 3000, with health at /api/health.
- **Postgres 18 with pgvector:** holds the memories collection and the mem0_app data, created on first boot.
- **OPENAI_API_KEY:** optional. Without it memory calls return provider_not_configured until you set it.

### Implementation Details for Mem0 vs Supermemory (Using Mem0 official docker image)

The API waits for Postgres, enables the vector extension, runs migrations, and listens dual-stack for Railway IPv6.

## How does Mem0 vs Supermemory compare against other memory layers for AI apps

### Mem0 vs Supermemory (Hosted Memory API Alternative)

- **What it stores:** Mem0 extracts facts from conversations with an LLM and keeps them as vectors in Postgres with pgvector, plus a change history. Supermemory ingests documents, URLs and conversations into a hosted memory graph.
- **Where it lives:** Mem0 data stays in the Postgres you run on Railway. Supermemory holds your data on its hosted service, which is less work but means another vendor sees your user data.
- **Where Supermemory wins:** If you want zero infrastructure and a team that already ships its SDK, the hosted option is the faster start.

### Mem0 vs Zep (Temporal Graph Memory Alternative)

- **Storage model:** Mem0 stores flat fact embeddings per user_id, agent_id or run_id. Zep builds a temporal knowledge graph that tracks how facts change over time.
- **Operations:** Mem0 self hosting is a Caddy proxy, a FastAPI server, a dashboard and Postgres. Zep's graph needs more moving parts to run yourself.
- **Where Zep wins:** If you need reasoning over relationships and time, a graph fits better than flat facts.

### Mem0 vs Letta (Stateful Agent Framework Alternative)

- **Scope:** Mem0 is a memory service your apps call over REST. Letta is a stateful agent server where memory lives inside the agent runtime.
- **Where Letta wins:** If you want the agent, its tools and its memory managed together, Letta covers more of the stack.

### Mem0 vs a Plain Vector Store (pgvector or Qdrant Alternative)

- **Extraction and dedup:** Mem0 decides which facts to keep, updates them when they change and deduplicates. A plain vector store saves whatever you insert, so you write that logic yourself.
- **Where the plain store wins:** If you already have clean, structured records and only need similarity search, a vector store is simpler and cheaper to run.

## How to use Mem0 vs Supermemory (the OSS AI memory layer)?

Once the deploy finishes, do these first on your Mem0 domain.

1. Open `/setup` on your Railway Mem0 domain and create the admin account. Registration closes after that.
2. On `mem0-api`, add `OPENAI_API_KEY` (and `OPENAI_BASE_URL` for a compatible provider). Without it, memory calls return `provider_not_configured`.
3. In the dashboard, create an API key under API Keys. It starts with `m0sk_`.
4. POST a short conversation to `/memories` with a `user_id`.
5. POST a query to `/search` with the same `user_id`.
6. Open `/docs` for the full OpenAPI spec.

```bash
curl -X POST https://your-mem0-domain/memories \
  -H "X-API-Key: m0sk_your_key" -H "Content-Type: application/json" \
  -d '{"messages":[{"role":"user","content":"I prefer email."}],"user_id":"alice"}'

curl -X POST https://your-mem0-domain/search \
  -H "X-API-Key: m0sk_your_key" -H "Content-Type: application/json" \
  -d '{"query":"how should I contact Alice?","filters":{"user_id":"alice"}}'
```

## How to self host Mem0 vs Supermemory on other VPS Services (Mem0 self hosting guide)

Self hosting Mem0 means running the open-source REST server and its Postgres with pgvector on your own machine.

### Clone the Repository

Clone the upstream Mem0 repo, which includes the server and dashboard with Docker Compose files.

```bash
git clone https://github.com/mem0ai/mem0.git
cd mem0
```

### Install Dependencies

You need Docker and Docker Compose on the VPS.

```bash
sudo apt-get update
sudo apt-get install -y docker.io docker-compose-plugin
```

### Configure Environment Variables

Create an env file with an OpenAI key, since Mem0 calls an LLM for extraction and an embedder for vectors.

```bash
cat > .env <
