not developers, look at GitHub - it's all for free
I do use the free stuff (GitHub, VS Code, etc).
And I also pay for NCrunch, Wallaby, RubyMine, Rider, GoLand, PyCharm, FastMail, PCloud, and more.
Most of the stuff I pay for has free equivalents (and yes, I know JetBrains have an all-products subscription rather than separate Ruby, .Net, Go, and Python, but I have reasons).
