Blazer

Open-source Rails engine for exploring data with SQL and building shareable charts and dashboards.

Pluginfree

Blazer is an open-source Ruby gem that adds a business intelligence dashboard directly into a Rails application, letting users explore data with SQL, build charts, and share dashboards with their team. It supports checks and alerts that notify the team by email or Slack when data looks wrong, and reuses the app's existing authentication. It's aimed at Ruby on Rails teams who want an internal analytics dashboard without adopting a separate BI product.
