Use Cases and Deployment Scope
We use it as the primary tool for database migrations, especially for solutions based on Java programming language. It has an intuitive way to operate within the Java ecosystem (Maven and Gradle especially). It has multiple functions/events to keep watch on the migration progress, so it's very useful for solutions that had several migrations with breaking changes on it, in a small period of time, you can subscribe to each event along the migration and see the whole progress of it, and detect any problems or odd behaviors at any time.
We use Flyway in every single environment, in my opinion, is a good tool for every single scenario and is not restrained to development environments only. I do think that you will need at least the Team edition, to take advantage of database objects as code on version control. This feature has a huge impact on the software development cycle as it works as a kind of ORM tool with also the migration capabilities.
