For those who already knew
https://verbhandbook.ninjal.ac.jp
https://vvlexicon.ninjal.ac.jp/db/
As of today, these sites no longer exist. I just found out the wrong way. But, using the WayBack Machine, I discovered that they had recently announced a URL change. They have become
https://www2.ninjal.ac.jp/verbhandbook/index.html
https://www2.ninjal.ac.jp/vvlexicon/
So you can update your bookmarks and favourites.
For those unfamiliar, the former gives every usage of certain verbs with sentences formation, sometimes videos etc, while the latter is a dictionary of compound verbs with examples (this one is also in English, the 詳細検索 option let you search verbs by the first (立つ) or second (上がる) verb of the compound one (立ち上がる for example)).
Maybe I'll end up liking them more or maybe they'll be updated, but for now I prefer the originals (the different parts of the handbook used different colours making it easier to read, and the verbs in the lexicon had an NLB link to a corpus database so you could find out more about how to use them).
We can't seem to access the lexicon database in the WayBack Machine, but the handbook is still usable, so I'll give the link too.

I don't know for the other websites of the National Institute for Japanese Language and Linguistics (NINJAL) as I didn't use them, but if you have other ones in your bookmarks, you should check them out.
As for me, I started coding a Python program a few weeks ago to do some web scraping on the lexicon. I have to redo everything from 0. Great…
