manage business-intelligence reports as SQL and Markdown code

About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

Evidence is an open-source BI tool that turns SQL and Markdown into interactive reports. Rather than a drag-and-drop dashboard builder, report definitions live in source control and can be published as static sites or hosted on Evidence Studio.

Before adoption

The authoring model differs from traditional GUI BI

Because report development is code-centric, teams with non-technical authors may need a different contribution workflow.

Keep CLI and project versions aligned around 40.1.8

Pinning the release line helps avoid build differences caused by CLI and project-version drift.
