Squasher is a Ruby command-line gem that compresses old ActiveRecord migrations into a single migration reflecting the final database state as of a given date. It reduces migration file clutter so that running db:migrate or bootstrapping a fresh database is fast in large Rails projects.

Use cases

• squash old rails migrations into one file
• speed up db:migrate on a large rails project
• clean up years of accumulated migration files
• make creating a new database faster
• compress migrations prior to a specific date
• generate a schema-like migration from existing migrations

When to choose

• you maintain a long-lived Rails or ActiveRecord app with hundreds of migrations
• you want a one-command way to archive migration history
• you need faster fresh database setup for CI or onboarding

When to avoid

• your project has few migrations and migrate is already fast
• you rely on data inserted by old migrations, since squashed migrations drop inserted records
• you are not using ActiveRecord migrations
