Matrix as a protocol and any of the clients that use it. SchildiChat and Element being two.
In theory you could even make that interoperable with WhatsApp i( in the EU) since the DMA makes that mandatory, I am not aware if anyone who did it though.
I used to run a matrix instance years ago. I remember the account setup being super difficult for my family members. And the client was so basic. Is it different nowadays?

yes; matrix has improved significantly - eg Element X is an unrecognisable improvement over the old Element app.
