Core 10k is here, and breakdown by WaniKani level. [Anki]
Expansion Pack is here – [Vocab] WaniKani Expansion Pack v1.0 - 1/13/2016 - Now on Memrise!. [Memrise] – I assume this one is pulled from common words in EDICT/ jisho.org
If you don’t want to use Anki, you might probably do the expansion pack (Memrise). Another one worth noting is iKnow.jp

I analyzed the overlap between WaniKani and Core; and also compare with JMdict / tangorin.com data. (JMdict is an update of EDICT)
I also analyzed “Common words,” but in my experience, I do have to know beyond Common words, but rarely beyond JMdict itself.
The analyzed workload is here.
