About

Hey! I'm Alexander.

Mprove is an Open Source Business Intelligence tool focused on Metrics.

With Mprove, instead of directly querying tables, you query semantic data models:

• For SQL data sources, see Malloy Models.
• For HTTP API data sources, see Store Models.

All Models, Charts, Reports and Dashboards are stored under git version control.

I started working on Mprove in 2015 inspired by Looker.

Understanding how things should work and look comes through a lot of trial and error. This is my third big attempt to build it right.

Initially, Mprove YAML had its own module for SQL transformation logic, similar to LookML. In 2025, I replaced this part with Malloy as the next-generation data modeling language.
