Hey HN,<p>We're really excited to release the first public version of Lightdash!<p>Lightdash is an open source alternative to looker that lets analysts define data transformations and metrics in one place. Lightdash gives analysts a BI platform built on the open-source tools they already love (dbt).<p>Github: <a href="https://github.com/lightdash/lightdash" rel="nofollow">https://github.com/lightdash/lightdash</a><p>Demo: <a href="https://www.loom.com/share/f3725e98ce4840bda3f719da647f58b0" rel="nofollow">https://www.loom.com/share/f3725e98ce4840bda3f719da647f58b0</a><p>Install: <a href="https://docs.lightdash.com/get-started/setup-the-demo-project" rel="nofollow">https://docs.lightdash.com/get-started/setup-the-demo-projec...</a><p>We believe that the future of the modern data stack lies in having a single source of truth for all your metrics.<p>Tools like dbt have made it possible for analysts to manage their transformations using SQL. But existing BI tools still hide away lots of extra business logic, meaning that metrics get scattered across the company (you know those 5 different calculations of revenue XD) and data context gets lost between tools.<p>With Lightdash, your BI tool is fully integrated with your dbt project. This means:<p>- You define your metrics right beside the rest of your data transformations, in dbt.<p>- Developing metrics becomes lightning fast: change some SQL or a metric and immediately see your data viz update<p>- All your dbt metadata (column and table descriptions, lineage, freshness, test results) is kept in sync with lightdash so you don't have to try to maintain it in multiple places.<p>Lightdash is still in the early days and we've got lots of work to do. Today, Lightdash supports most popular databases and warehouses but is only tested with PostgreSQL and BigQuery - so, if you try it with another database, it'd be great to hear about your experience using it!<p>We'd love any feedback or to hear about how you're solving BI at your company today :)<p>Thanks!<p>The lightdash team
