Introduction

Installation

To get started with Lago on your own infrastructure, you'll need Docker, Docker Compose, and Git. The self-hosted setup allows for full control over your data and environment.

Here's a quick start guide:

# Clone the repo
git clone --depth 1 https://github.com/getlago/lago.git
cd lago

# Generate RSA key
echo "LAGO_RSA_PRIVATE_KEY=\"$(openssl genrsa 2048 | openssl base64 -A)\"" >> .env
source .env

# Start Lago
docker compose up

After running these commands, the Lago UI will be accessible at http://localhost and the API at http://localhost:3000. For advanced configurations or if your server is not at localhost, refer to the official self-hosted documentation.

Examples

Lago is an API-first platform, meaning every feature is accessible via its powerful REST API. Developers can integrate Lago into their applications using official SDKs available for Node.js, Python, Ruby, and Go.

For practical implementation examples, including how to send events, manage subscriptions, and generate invoices, the official documentation provides detailed guides. You can also explore various billing templates that reproduce pricing models from leading companies, helping you quickly set up complex billing logic.
