Then your next best bet is Matrix.org. Not to the same security standard as Signal, but if you don't have a specific threat against you then it's fine.

Cons of Matrix: encryption breaks constantly. Right now I’m stuck in a fun loop of endlessly changing recovery keys: https://github.com/element-hq/element-web/issues/31392
