Flameshot is local. May have a subscription service, not sure.
But flameshot is extremely fast and does 95% of what I'd do in gimp anyway, without having to open a whole image editor and saving a picture.
I can directly copy it to the clipboard and paste it somewhere.
Yeah it sounds good, I just rarely do screenshots so I stick with what I know. If my workflow required a lot of screenshots I might either automate it a bit more or look at other tools.
I'm actually about as likely to just pull out my phone and take a picture of the screen as to use software-based screenshots.
