Self Host LLMGateway

LLMGateway is a self-hostable platform that provides a unified API gateway for multiple LLM providers. This guide offers two simple options to get started.

Prerequisites

Latest Docker
API keys for the LLM providers you want to use (OpenAI, Anthropic, etc.)

Option 1: Unified Docker Image (Simplest)

This option uses a single Docker container that includes all services (UI, API, Gateway, Database, Redis).

# Run the container
docker run -d \
  --name llmgateway \
  --restart unless-stopped \
  -p 3002:3002 \
  -p 3005:3005 \
  -p 4001:4001 \
  -p 4002:4002 \
  -v ~/llmgateway_data:/var/lib/postgresql/data \
  -e OPENAI_API_KEY=sk-your_openai_key_here \
  -e AUTH_SECRET=your-secret-key-here \
  ghcr.io/theopenco/llmgateway-unified:latest

Note: it is recommended to use the latest version tag from here instead of latest: https://github.com/theopenco/llmgateway/releases

Using Docker Compose (Alternative for unified image)

# Download the compose file
curl -O https://raw.githubusercontent.com/theopenco/llmgateway/main/infra/docker-compose.unified.yml
curl -O https://raw.githubusercontent.com/theopenco/llmgateway/main/.env.example

# Configure environment
cp .env.example .env
# Edit .env with your configuration

# Start the service
docker compose -f docker-compose.unified.yml up -d

Note: it is recommended to replace the latest version tag in the image with the latest version from here: https://github.com/theopenco/llmgateway/releases

Option 2: Separate Services with Docker Compose

This option uses separate containers for each service, offering more flexibility.

# Clone the repository
git clone https://github.com/theopenco/llmgateway.git
cd llmgateway

# Configure environment
cp .env.example .env
# Edit .env with your configuration

# Start the services
docker compose -f infra/docker-compose.split.yml up -d

Note: it is recommended to replace the latest version tag in all images in the compose file with the latest version from here: https://github.com/theopenco/llmgateway/releases

Accessing Your LLMGateway

After starting either option, you can access:

Web Interface: http://localhost:3002
Documentation: http://localhost:3005
API Endpoint: http://localhost:4002
Gateway Endpoint: http://localhost:4001

Required Configuration

At minimum, you need to set these environment variables:

# Database (change the password!)
POSTGRES_PASSWORD=your_secure_password_here

# Authentication
AUTH_SECRET=your-secret-key-here

# LLM Provider API Keys (add the ones you need)
OPENAI_API_KEY=sk-...
ANTHROPIC_API_KEY=sk-ant-...

Basic Management Commands

For Unified Docker (Option 1)

# View logs
docker logs llmgateway

# Restart container
docker restart llmgateway

# Stop container
docker stop llmgateway

For Docker Compose (Option 2)

# View logs
docker compose -f infra/docker-compose.split.yml logs -f

# Restart services
docker compose -f infra/docker-compose.split.yml restart

# Stop services
docker compose -f infra/docker-compose.split.yml down

Build locally

To build locally, you can use the *.local.yml compose file in the infra directory, which will build the images from the source code.

All provider API keys

You can set any of the following API keys:

OPENAI_API_KEY=
ANTHROPIC_API_KEY=
VERTEX_API_KEY=
GOOGLE_AI_STUDIO_API_KEY=
INFERENCE_NET_API_KEY=
TOGETHER_AI_API_KEY=

Next Steps

Once your LLMGateway is running:

Open the web interface at http://localhost:3002
Create your first organization and project
Generate API keys for your applications
Test the gateway by making API calls to http://localhost:4001

For more information, see the API Documentation and User Guide.
