Yes, Plex comes with support for Netflix via a plug-in. The Netflix plug-in on Plex effectively adds an option to your video sections on the Plex media library. Using the plug-in, you can browse Netflix, search for a wide range of available movies, web series, and TV shows, and watch them without exiting from the Plex. However, the Netflix plug-in for Plex works only with the MacOS X version and not on Windows.
