Why not using a CAT tool like Crowdin to accelerate translations ?

Probably no time to do it. And crowdin only has generous free plan for open source software projects.

@notaLamer What do you mean probably no time to do it? what time ?
I said LIKE Crowdin, similar alternative open source or something.
But what do you really mean no time to do it, this is very weird

The full sentence: The single software developer and founder of Tixati Inc. is probably not pursuing a CAT tool integration due to a lack of time. Further the Template[1] file has not been updated since its inception in 2021. I cannot but think of the very same reason as above.

How do you know ?

If the cost of Crowdin is a concern, there is an open-source, free alternative called Weblate.
Regarding time, I believe that some of the managers and moderators and people on this platform are willing to assist.
