We're d-band — Here's Why We Build Open-Source Tools

This is the first post from d-band. We're not launching a product today. We're introducing ourselves.

Liquibase for one system, SSDT for another, custom shell scripts to glue it all together, a shared spreadsheet to track what actually deployed where. It worked. Until it didn't.

We didn't find one that hit all of those marks without a significant lic
