Blazer
Business intelligence made simple
Blazer is a business-intelligence engine for Rails that lets teams write SQL in the browser, visualize the results, and share insights without leaving their app. It turns raw database queries into charts, tables, and dashboards, so non-engineers can explore data with minimal friction. Queries can accept parameters, enabling reusable reports for different time ranges, segments, or customers. Access controls and audit trails help teams manage who can run, edit, or view sensitive analyses. Scheduled checks and alerts turn BI into proactive monitoring by notifying you when metrics cross thresholds or regress. Because it’s a Rails engine, it integrates into your app’s authentication, layouts, and deployment workflows, reducing the overhead of maintaining a separate BI stack.
