# Deploy and Host ChromaDB on Railway

ChromaDB is an open-source vector database designed for AI applications that use embeddings for semantic search, retrieval-augmented generation (RAG), recommendations, and similarity search. This template deploys a persistent ChromaDB server on Railway with built-in storage, allowing any application to connect over HTTP.

## About Hosting ChromaDB

This template deploys ChromaDB as a standalone HTTP service with persistent storage using Railway Volumes. Once deployed, your vector database remains available across restarts and redeployments while exposing a REST API that can be accessed from applications written in Node.js, Python, Go, Java, Rust, PHP, or any language capable of making HTTP requests.

The template is ideal for AI applications that need a self-hosted vector database without managing infrastructure. Simply deploy the template, attach a persistent volume, and connect your application using the generated Railway domain or private network URL.

## Common Use Cases

- Retrieval-Augmented Generation (RAG) for AI chatbots and AI assistants
- Semantic search across documents, websites, PDFs, and knowledge bases
- Vector embedding storage for recommendation systems and similarity search

## Dependencies for ChromaDB Hosting

- Railway Volume mounted at `/data` for persistent storage
- Official `chromadb/chroma` Docker image

### Deployment Dependencies

- Chroma Documentation: https://docs.trychroma.com/
- Chroma GitHub Repository: https://github.com/chroma-core/chroma
- JavaScript SDK: https://www.npmjs.com/package/chromadb
- Python SDK: https://pypi.org/project/chromadb/

### Implementation Details

This template stores all database files in a persistent Railway Volume mounted at `/data`.

**Dockerfile**

```dockerfile
FROM chromadb/chroma:latest

ENV IS_PERSISTENT=TRUE
ENV PERSIST_DIRECTORY=/data

EXPOSE 8000
```

**Node.js**

```javascript
import { ChromaClient } from "chromadb";

const client = new ChromaClient({
  host: "your-chroma-service.railway.internal",
  port: 8000,
  ssl: false,
});
```

**Python**

```python
import chromadb

client = chromadb.HttpClient(
    host="your-chroma-service.railway.internal",
    port=8000,
)
```

## Why Deploy ChromaDB on Railway?

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 ChromaDB on Railway, you are one step closer to supporting a complete full-stack AI application with minimal operational overhead. Host your servers, databases, AI agents, vector stores, and more on Railway.
