Providers

Embex supports a wide range of vector databases. Switching providers is as simple as changing the provider and URL parameters.

The Recommended Path

Stage	Provider	Why?
Development	LanceDB	Zero Setup. Runs locally (embedded). No Docker or API keys needed.
Production	Qdrant / Pinecone / Milvus	Scale. Managed services, high throughput, distributed.

---

LanceDB (Recommended for Dev)

Start here. LanceDB runs in-process and stores data in the local filesystem.

Python

# Persist to local folder (creates ./data directory)
client = await EmbexClient.new_async(provider="lancedb", url="./data")

Node.js

// Persist to local folder (creates ./data directory)
const client = await EmbexClient.newAsync("lancedb", "./data");

Cloud Providers (Production)

When you’re ready to scale, switch to a cloud provider.

Pinecone

Managed serverless vector database.

Python

client = await EmbexClient.new_async(
    provider="pinecone",
    url="https://index-name.svc.pinecone.io",
    api_key="your-api-key"
)

Node.js

const client = await EmbexClient.newAsync(
  "pinecone",
  "https://index-name.svc.pinecone.io",
  "your-api-key"
);

Qdrant

High-performance Rust vector database (Cloud or Self-Hosted).

Python

# Qdrant Cloud
client = await EmbexClient.new_async(
    provider="qdrant",
    url="https://xyz-example.eu-central.aws.cloud.qdrant.io:6333",
    api_key="your-api-key"
)

# Local Docker
client = await EmbexClient.new_async(
    provider="qdrant",
    url="http://localhost:6333"
)

Node.js

// Qdrant Cloud
const client = await EmbexClient.newAsync(
  "qdrant",
  "https://xyz-example.eu-central.aws.cloud.qdrant.io:6333",
  "your-api-key"
);

// Local Docker
const client = await EmbexClient.newAsync("qdrant", "http://localhost:6333");

Other Providers

Milvus

Python

client = await EmbexClient.new_async(provider="milvus", url="http://localhost:19530")

Node.js

const client = await EmbexClient.newAsync("milvus", "http://localhost:19530");

Weaviate

Python

client = await EmbexClient.new_async(provider="weaviate", url="http://localhost:8080")

Node.js

const client = await EmbexClient.newAsync("weaviate", "http://localhost:8080");

Chroma

Python

client = await EmbexClient.new_async(provider="chroma", url="http://localhost:8000")

Node.js

const client = await EmbexClient.newAsync("chroma", "http://localhost:8000");

PgVector

Python

client = await EmbexClient.new_async(
    provider="pgvector",
    url="postgresql://user:pass@localhost:5432/db"
)

Node.js

const client = await EmbexClient.newAsync(
  "pgvector",
  "postgresql://user:pass@localhost:5432/db"
);
