Going away from Zlib proper but staying with its format, there’s libdeflate[1], an implementation that’s substantially faster on modern machines but can’t stream (although I see no reason why it couldn’t, probably just for simplicity due to its origins as a baseline fast compressor[2]), and of course Zopfli[3], a glacially slow compressor that’s somewhat (and occasionally a lot) better.
