While numerical relativity is a standard tool in the computation of accurate gravitational waveforms in compact object astrophysics, its application to cosmology is not yet so widespread. I will discuss the opportunities and challenges of applying this tool to different aspects of cosmology, and illustrate them using the example of studying an inhomogeneous period before inflation began.

The talk will be mainly based on the recent Living Review article https://link.springer.com/article/10.1007/s41114-025-00058-z.
