They make those too. HyperRAM is pretty popular for small FPGA projects: https://www.mouser.com/new/issi/issi-hyperram/ - there are tradeoffs in potential performance/interface/usability/etc but you end up saving a lot of LUT's and troubleshooting time.

Is there free and functional controller for HyperRAM available? In theory this type of memory is nice, but with no free IP block for this memory, it is a show stopper.

The controller is really not very complex, so it shouldn't be a showstopper.
