Evidence

Evidence is an open-source code-based BI tool that lets analysts write reports as Markdown files containing SQL queries and visualisation components, with the output deployed as a static site. It is free to self-host and offers a paid cloud product for teams that want hosting and access controls. Evidence appeals to analytics engineers who want their reports to live in git, versioned and reviewed like code, and is often compared to Lightdash and Metabase for code-first workflows.
