The spectrum of gravitational waves emitted throughout the history of the universe is known to extend to frequencies much higher than current large-scale detectors are exploring. Therefore, several projects are now under way to survey high-frequency gravitational waves (HFGWs). First, I will give an overview on the physics potential of HFGW detection for BSM physics and cosmology. Then, I will motivate microwave cavities as novel tools for HFGW searches and introduce an ongoing DESY/Uni Hamburg/FNAL project to use the superconducting 'MAGO' cavity as such a detector. Last, I will discuss synergies with searches for axion-like dark matter to cover even higher frequency ranges.
