Overview
Evidence is an open-source, code-based BI tool that lets you write reports as Markdown files mixed with SQL queries and chart components. It compiles to a fast static web app, making analytics version-controllable and reviewable like code. It suits engineering-minded teams who want reproducible, polished data products instead of click-built dashboards.
Where it falls short of Tableau
- Code-first workflow excludes non-technical, point-and-click business users
- Not designed for interactive ad-hoc exploration; reports are authored, not browsed freely
- No drag-and-drop visual builder or pivot-table exploration like Tableau/Power BI
- Limited governance, permissions, and live-querying features compared to enterprise BI
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
