I use flex. Faster than awk or python. It produces relatively seems to be available "everywhere" because it is a build requirement for so many software programs. For exampole, NetBSD toolchain includes it. It is a build requirement for Linux kernel.^1 I have even used it with Interix SFU on Windows before WSL existed.

I do not use jq. Too complicated for me. Overkill. I created statically-linked program less than half the size of official statically-linked jq that is adequate for own needs. flex is a build requirement for jq.

Using C program generated with flex is faster than AWK or Python. Flex is required to compile the awk interpreter, as well as the jq interpreter. I use a custom scanner generated by flex to process JSON.
