This has been a big question lurking at the back of my head. From what I see, GnuSTEP nowadays is primarily a "hobby" project of a small but tightly-knit group of people. However I haven't seen a large commercial (off-the-shelf) application that uses it, apart from the small applications that comes with the GnuSTEP distribution.

Heck, since even Ubuntu doesn't really use it then is GnuSTEP really more than being a "hobby" framework?

I know that Sony's SNAP at one brief moment uses GnuSTEP, but they killed the platform before it can do anything meaningful.

There's a list of corporate developers and users. I'm at the inception of a project using GNUstep. I also still work with the people at Brainstorm (see the list), and used to work there myself: they employ some of the GNUstep project maintainers and their technology stack is based on it. However that's not a COTS package.

TestPlant's product, EggPlant is a cross-platform Objective-C product based on GNUstep. They document that in their press release(PDF).

What commercial product did any of those listed companies release that's based on GNUStep? Just because they are using Objective C doesn't make it GNUStep. I can't find any information on those listed companies website where it mentions GNUStep. May be the guys running them are the maintainers of GNUStep or something? – kadaj Mar 29 '12 at 8:19

Alright. Agreed :D – kadaj Mar 29 '12 at 10:03
From GnuSTEP's list of developers/users, I couldn't find any application that individuals can buy at an affordable price (say, < $1000 per license). Also it sounds like that list of clientele is mostly "legacy" users of the NextSTEP days (having legacy code when NextSTEP was popular in corporates). – adib Mar 29 '12 at 18:54
@GrahamLee It matters when you're selecting a framework for developing indie applications. Your last comment sounds like it answers why indies choose to go with Cocotron instead. – adib Mar 31 '12 at 2:30

There's Étoilé, a project trying to make a desktop environment based on GnuSTEP, but it seems to be far from anything usable yet.

would you mind explaining more on what it does and what it's good for? "Link-only answers" are not quite welcome at Stack Exchange – gnat Aug 31 '13 at 16:03
