I'm sometimes asked if I'm aware of any open-source implementations of MuZero. In addition to the official pseudocode, a variety of researchers have made their own implementations and shared them online.
I have not checked these for correctness or completeness, but I still believe that you may find them useful. In no particular order:

If you know any others, please let me know and I'll add them!
If you want to replicate MuZero or try other RL ideas on board games, I can recommend the excellent collection of environments in OpenSpiel.
