What is ridgepole?

Ridgepole lets you define your database schema using the familiar Rails DSL, storing the definition in version‑controlled files. It compares the DSL against the live database and generates the necessary migration steps to keep them in sync, similar to infrastructure‑as‑code tools. Because the schema lives in code, you can review changes, roll back easily, and integrate schema updates into your CI/CD pipelines. Ridgepole works with any Rails‑compatible database and runs as a simple Ruby command‑line utility.
