A Ruby gem for Rails that catches unsafe database migrations in development by detecting potentially dangerous operations like removing columns or adding indexes non-concurrently. It blocks these operations by default and provides instructions on safer alternatives, supporting PostgreSQL, MySQL, and MariaDB.

Use cases

• prevent downtime from dangerous Rails migrations
• catch unsafe column removals before deploying
• get guidance on zero-downtime schema changes
• block non-concurrent index creation on Postgres
• safely backfill data in large tables
• enforce safe migration practices across a Rails team

When to choose

• you run a Rails app with PostgreSQL, MySQL, or MariaDB and want to avoid migration-caused outages
• your team deploys schema changes to large production tables
• you want built-in guidance for safe migration patterns

When to avoid

• you use a framework other than Rails or an ORM other than Active Record
• your database is small or rarely migrated and the overhead isn't justified
• you need migration safety checks outside Ruby
