@feditips @MastodonEngineering Yes.

First, there's #Weblate. I strongly recommend it, I have recently started using it for my own games. #Minetest also uses it.

Then, there's translatewiki.net. #FreeCol uses it and a number of other projects. Also good.

There are also #Zanata and #Pootle but I have no experience with these and they may be outdated (check for yourself).

Then, there are translation services tailored towards specific software:

#Pontoon for Mozilla.
#Eints for #OpenTTD.
