Rill

Rill takes a developer-friendly approach, letting you define your data model in YAML and ship interactive dashboards in minutes rather than hours. The semantic layer is transparent and version-controlled alongside your code, so changes go through git workflows like any other software. Performance is a core feature, dashboards stay responsive even on millions of rows by running aggregations in-database, not in the browser.

It's ideal if you have technical data teams who'd rather own their analytics code than drag-and-drop in a GUI. You'll get faster iteration than traditional BI tools, and AI agents can query your semantic layer directly, making it useful for embedded analytics and self-serve scenarios where your users are developers.
