Docker Compose runs a lightweight, single-node Laminar on one machine: frontend, app server, PostgreSQL, ClickHouse, and Quickwit for full-text search. It is the fastest way to self-host for local development and small deployments. For the full production stack (with RabbitMQ, Redis, and a dedicated processing consumer), use the Helm chart on Kubernetes.

​
Install

git clone https://github.com/lmnr-ai/lmnr
cd lmnr
docker compose up -d
The dashboard is available at http://localhost:5667/. Create a project through the onboarding flow, then grab your project API key from project settings.
docker compose up -d brings up the lightweight stack. For a heavier single-node setup closer to production, the repo also ships docker-compose-full.yml (docker compose -f docker-compose-full.yml up -d), which adds RabbitMQ for queued span processing.

​
Point the SDK to your instance

Initialize the SDK with the local app server’s host and ports. baseUrl / base_url is the scheme and host only; the ports go in httpPort / grpcPort. 
import { Laminar } from '@lmnr-ai/lmnr';

Laminar.initialize({
  projectApiKey: "<YOUR_PROJECT_API_KEY>",
  baseUrl: "http://localhost",
  httpPort: 8000,
  grpcPort: 8001,
});

​
Access control

By default, any user can sign in to your self-hosted instance. To restrict access to specific GitHub users, enable GitHub OAuth: 
AUTH_GITHUB_ID=your_github_oauth_app_id
AUTH_GITHUB_SECRET=your_github_oauth_app_secret
Then create an allowed-emails.json file in your project root: 
{
  "emails": [
    "user1@example.com",
    "user2@example.com"
  ]
}

​
AI features

Chat-with-trace, SQL-with-AI, and Signals need an LLM provider. Set the provider and key in your environment before bringing the stack up: 
LLM_PROVIDER=gemini       # gemini (default), openai, or bedrock
LLM_API_KEY=your-llm-key
The Helm chart exposes the same variables plus per-tier model overrides and OpenAI-compatible gateways. See the configuration reference for the full set.
