Evidence

Evidence provides a code‑first approach to business intelligence, letting developers author reports with SQL queries embedded in markdown files. The markdown pages are compiled into a static website where query results are visualized through built‑in chart components, and templating features such as loops and conditional statements enable dynamic page generation from a single source file.

The tool is self‑hostable and distributed under an MIT license, offering a free tier without subscription requirements. It integrates with a range of data sources—including Snowflake, BigQuery, and ClickHouse—and employs a high‑performance query engine with caching and row‑level security to deliver sub‑second interactions even on large datasets.

Targeted at engineers and data teams, Evidence supports version‑controlled development, real‑time syntax validation, autocomplete, and an optional AI assistant for documentation lookup and debugging. The resulting data products can be published internally, shared with customers, or embedded in other applications.
