SOS, 155 Bytes

!+!-!!+!-!!!!+!!-!!+!-!+!-!+!!-!+!!-!!!+!!-!+!!-!!!+!!-!+!!!!-!!+!-!+!!-!!!!+!-!!!!!!+!-!+!-!+!!!-!+!!-!+!!!!-!+!!!-!!+!-!!+!!-!+!!-!!!+!!-!!+!-!!+!-!!!!+!

Explanation:

Each ! outputs a single bit. That bit is 0 if the current stack is empty, and 1 otherwise. Initially the stack is empty. + adds something (an empty stack) to it, and - removes it. As soon as 8 bits are output, the corresponding byte is sent to stdout. Therefore the sequence up to the 8th !, !+!-!!+!-!!! outputs the bit sequence 01001000, which is the ASCII code for the letter H.

The last character uses the fact that if at the end of the program less than 8 bits are output, the value is left-padded with zeros, and the resulting byte is output. So with comments (and spaces to make the output commands line up), the program reads like this:

 !+!-! !+!-! ! !  Output 01001000, i.e. H
 !+! !-! !+!-!+!  Output 01100101, i.e. e
-!+! !-!+! !-! !  Output 01101100, i.e. l
 !+! !-!+! !-! !  Output 01101100, i.e. l
 !+! !-!+! ! ! !  Output 01101111, i.e. o
-! !+!-!+! !-! !  Output 00101101, i.e. comma
 ! !+!-! ! ! ! !  Output 00100000, i.e. space
 !+!-!+!-!+! ! !  Output 01010111, i.e. W
-!+! !-!+! ! ! !  Output 01101111, i.e. o
-!+! ! !-! !+!-!  Output 01110010, i.e. r
 !+! !-!+! !-! !  Output 01101100, i.e. l
 !+! !-! !+!-! !  Output 01100100, i.e. d
    +!-! ! ! !+!  Output 00100001, i.e. exclamation mark

They kept saying that jq is the language of September 2021. Still surprised no one even made a Hello, World! on it.
