Evidence is an open-source (MIT) business-intelligence-as-code framework that turns SQL queries plus Markdown into fast, version-controlled static data apps and dashboards. It is built on Svelte/Vite, runs queries through a DuckDB-WASM "Universal SQL" engine, and is consumed as a framework/CLI rather than a hosted REST API. Evidence Cloud adds managed hosting, a managed query engine, scheduled data syncs, and AI authoring assistance.
