In FRIDA mode, you can fuzz binary-only targets as easily as with QEMU mode.
FRIDA mode is most of the times slightly faster than QEMU mode. It is also
newer, lacks COMPCOV, and has the advantage that it works on MacOS (both intel
and M1).

less conducive to parallelization. But for binary-only fuzzing, it gives a huge
speed improvement if it is possible to use.
If you want to fuzz a binary-only library, then you can fuzz it with frida-gum
via frida_mode/. You will have to write a harness to call the target function in
the library, use afl-frida.c as a template.
You can also perform remote fuzzing with frida, e.g., if you want to fuzz on
iPhone or Android devices, for this you can use
