I stumbled on this question that basically ask 'What type of tool is X'.
Is this on-topic based on this bullet from the help-center
•software tools commonly used by programmers
Looking at the answers on the question at hand you have to stretch 'commonly'.
Based on answers here:
Asking if certain tools contain certain features?
Any way to ask about the objective existence of a library/tool for a specialized programming task?
Are SO questions about general-purpose tools off-topic?
I could argue that this question is a corner-case for it's on-topic-ness.
I voted to close with reason 'asking for off-site resource' but I'm unsure if that is correct.
Should I retract my close-vote?
