The cosmological 21-cm signal is a powerful probe of the early Universe. There are a wide range of codes have been developed in the community to simulate the signal, from numerical to semi-numerical to analytical. Some codes do numerical radiative transfer, some do not. Some are very fast, others are slow. This repository aims to provide a comprehensive list of the various 21-cm simulation codes that have been developed in the community. As a broader tool, it also now includes emulators and inference tools that are commonly used in conjunction with 21-cm simulation codes.
The list is compiled in a publicly editable Google Sheet: Link to Google Sheet.
The list is of-course free to use, modify and distribute. If you notice any errors in the list, please feel free to correct it. This is a community-driven repository so the more contributions, the better it is! You can always raise a GitHub issue or contact me at my email if you have any ideas/questions/suggestions.
