Hi, there's [else/pvoc.live~] which is a fft/phase-vocoder based real time pitch shifter and time stretcher. It's also based in Miller's phase vocoder example. It uses a delay line but I use the [del~] object from ELSE instead of [delread4~] (I prefer to use the new name instead of the old [vd~] one). At the time I had to use this object from ELSE instead because [delread4~] had a bug that got fixed this year.

There's also [else/stretch.shift~], which is granular based but it's quite the same, just not FFT based, and I also like to interpret FFT as a form of granular by the way.
