About Evidence

Evidence is a code-first business intelligence tool, released as open source, offered in place of drag-and-drop BI products. Reports and dashboards are written as Markdown with SQL queries, which keeps them in version control and lets analysts build interactive data visualizations without a point-and-click builder.

The README calls it agent-ready: you can develop with Evidence's own agent, or locally with coding assistants such as Claude Code or Cursor. Topics mention dbt, DuckDB, Svelte, Tailwind CSS, WebAssembly and self-hosting. A project is created from an installer for macOS, Linux or Windows, and the result can be published on Evidence Studio for hosted reports, or built as a static site and self-hosted on your own infrastructure.

Evidence is written in TypeScript with Svelte and licensed under MIT, and has a Slack community for help. It suits data teams and analysts who are comfortable with SQL and want reports reviewed and deployed like software, rather than assembling dashboards in a GUI.
