## What it is
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
