Strong Migrations
A Ruby gem that catches unsafe database migrations in development for PostgreSQL, MySQL, and MariaDB.
What is Strong Migrations?
Strong Migrations is a Ruby gem that helps developers write safer database migrations by detecting potentially dangerous operations before they reach production. It catches issues like removing columns, changing column types, or adding indexes non-concurrently, which can cause downtime or application errors. The gem provides actionable alternatives and enforces safety unless explicitly overridden.
Rails developers and teams working with PostgreSQL, MySQL, or MariaDB databases who need to manage schema changes without causing production downtime or errors.
Developers choose Strong Migrations because it proactively prevents migration-related outages, educates on best practices, and supports multiple databases with minimal configuration. Its battle-tested reliability from use at scale (like Instacart) adds confidence.
