This doesn't appear to support any FPGAs other than their FPGA chiplet [1]. Also, like UncleOxidant said, the most complex parts of this toolchain are just existing open-source tools (Yosys and VPR).

This seems like a useful toolchain for ZeroASIC customers who are using their hardware, but not for FPGA enthusiasts more broadly.
