An Elixir tool that analyzes database migrations to detect potentially dangerous or destructive operations.
What is excellent_migrations?
Excellent Migrations is a static analysis tool for Elixir applications that checks the safety of database migrations. It analyzes migration files to detect over 15 types of potentially dangerous operations—like removing columns, adding indexes non-concurrently, or executing raw SQL—that can lead to downtime, data corruption, or performance issues in production.
Elixir developers and teams using Ecto for database migrations, particularly those operating PostgreSQL databases in production environments where zero-downtime deployments and data integrity are critical.
Developers choose Excellent Migrations because it proactively catches unsafe migration patterns early in development, integrates seamlessly as a Credo check or standalone mix task, and provides PostgreSQL-specific validations and actionable safety guidance to enforce best practices.
