Linux and OSX end hosts now routinely run fq_codel by default.  That's an awfully large installed base, both of FQ and of Codel.  It is perhaps worth observing that these are rarely bottlenecks for Internet paths, though they might be for LAN paths.

The IQrouter is probably the best example of a commercial middlebox that does FQ, in this case using Cake.  I hear that it is now being sold in re-branded form to certain large ISPs, but I could be wrong about that.  I've CC'd Jonathan Foulkes for comment.

There's also a large French ISP which has done fq_codel on its last mile for quite some time.
