Evidence
Business intelligence as code with SQL and Markdown

Evidence is an open-source, code-based alternative to drag-and-drop BI tools for building interactive data products. It generates a web app from Markdown pages that run embedded SQL queries and render charts and UI components.
Key Features
- Build reports and dashboards from Markdown with embedded SQL queries
- Component-based, interactive visualizations rendered from query results
- Templated pages plus loops and conditional logic for reusable reporting
- Developer-friendly workflow designed for version control and code review
- Supports connecting to common analytical databases and warehouses
Use Cases
- Internal BI reporting portals with a narrative format (metrics plus commentary)
- Customer-facing analytics and embedded reporting in product documentation sites
- Rapid exploratory analysis shared as reproducible, versioned reports
Evidence is well-suited for teams that prefer writing SQL and keeping analytics artifacts in Git. It provides a straightforward path from queries to polished, shareable data experiences without relying on a drag-and-drop editor.
