How about General Use?

[aaronj0]

The only other generic options I could find are "Other Audience" and "End Users/Desktop", I am not sure if that is meant for our library. Maybe "Other Audience" but End Users/Desktop does not apply in our case.
Developers + Science/Research seems to be the category used by developer tools

[vgvassilev]

Adding developers makes sense to me.

[aaronj0]

Addressed

[vgvassilev]

Lgtm!
