We maintain a commercial, Fortran-specific IDE, Simply Fortran, that ships with the GNU Fortran compiler (at least on Windows and macOS): https://simplyfortran.com
It has many of the usual IDE expectations built in like autocomplete, project management, debugging, Git integration, etc. Our Windows distribution adds a few niceties like a Fortran-oriented (though basic) GUI library, a Windows-native coarray implementation (that doesn't use MPI), Windows-native OpenMP and threading, and a binary package manager for pre-built libraries.
We're decidedly a small player in a niche market, but I like to think Simply Fortran makes life easier for Fortran developers. Sorry for the self-promotion!
Thanks for a shout-out to Simply Fortran! I'm the primary developer behind it (had to finally create an account to reply...), and we're always trying to improve the development environment.
