The main use case I found was that my production database had a bunch of changes we did manually (early stage startup and all), so I used Migra to figure out what changes we needed to make to keep the migrations in sync with what was actually in production.

The more common use case is this idea in development—-experiment with different schemas manually and then use a tool like Migra to figure out what migration to write, without keeping in your head what changes you’ve made.
