## What it is
Blazer is a Ruby on Rails engine that provides a simple business intelligence dashboard for exploring data with SQL. It lets users run queries, create charts and dashboards, set up checks and alerts, and share insights with their team.

## Use cases
- run ad-hoc SQL queries against a database through a web UI
- create charts and dashboards from SQL queries
- set up email alerts when bad data appears
- share SQL reports with a team
- explore data across multiple databases like PostgreSQL, MySQL, and Redshift
- track and audit all queries run by users

## When to choose
- you have a Rails app and want to add self-serve SQL exploration for your team
- you need lightweight business intelligence without deploying a separate BI stack
- you want scheduled checks and email alerts on data quality
- you need query auditing and permissions tied to your existing authentication

## When to avoid
- your project is not Ruby on Rails
- you need a full-featured BI suite with drag-and-drop report builders
- you need to expose dashboards to non-technical users without SQL knowledge
- you cannot grant database access to a web application
