Evidence

What is Evidence?

Evidence is an open source, code-based business intelligence platform that enables users to build data products using SQL and markdown instead of traditional drag-and-drop interfaces. The tool allows analysts and developers to create polished reports and dashboards by writing queries and documentation in code, making it particularly suited for teams with SQL expertise who prefer version control and code-based workflows. Unlike conventional BI tools that rely on graphical interfaces, Evidence treats analytics as code, allowing data products to be built, tested, and deployed through familiar development processes. Users define their data visualizations and reports using SQL for data querying and markdown for content structure and presentation. The platform is fully open source and available at no cost, with source code accessible on GitHub. Evidence targets organizations and individual contributors who want more control over their analytics infrastructure, prefer code-based collaboration, and value the ability to integrate analytics into existing development workflows. The tool is designed for users already comfortable with SQL who want to reduce friction in creating and maintaining data products without relying on proprietary BI platforms. Evidence includes documentation, example projects, and community support through Slack to help users get started and troubleshoot implementation.
