I find it a little weird to mix applications and libraries in the same list. But if libraries are considered, I would definitely nominate Hibernate: the most powerful ORM out there accross all languages, and it's been a must grab for any of my projects for almost 2 decades.

I haven't been much of an ORM userm but what makes it so special? Anything comparable in Javascript or Python land?
