Quite recently I learned that there is also a Finnish equivalent "Suomen etymologinen sanakirja" available online. kaino.kotus.fi/ses/

Likewise an excellent resource for those interested in Finnish words.

There is still a bunch of work that needs to be done but it is already in a very usable state. I have found it quite useful for myself when watching streams and building decks as I can quickly check how some specific keywords work and such.
