## What it is
DataLens is an open-source business intelligence and data visualization system originally developed and used as the primary BI tool at Yandex. It is deployed via Docker Compose and provides dashboards, SQL-based analytics, and reporting.

## Use cases
- build interactive dashboards from sql databases
- self-host a business intelligence tool
- create reports and charts for company data
- visualize analytics data without paying for saas bi
- explore data with sql queries and visualizations
- replace proprietary bi platforms with an open-source alternative

## When to choose
- you want a self-hosted, docker-based BI platform
- your team needs dashboards and reporting on top of SQL data sources
- you want a battle-tested tool proven at Yandex scale
- you prefer an Apache-2.0 licensed alternative to commercial BI

## When to avoid
- you need a lightweight embedded charting library rather than a full BI platform
- you cannot run Docker or manage multi-container deployments
- you need extensive third-party integrations outside its supported connectors
- you want a fully managed service without self-hosting overhead
