You can use ropper to display information about binary files in different file formats
and you can search for gadgets to build rop chains for different architectures

supported filetypes:
  ELF
  PE
  Mach-O
  Raw

supported architectures:
  x86 [x86]
  x86_64 [x86_64]
  MIPS [MIPS, MIPS64]
  ARM/Thumb [ARM, ARMTHUMB]
  ARM64 [ARM64]
  PowerPC [PPC, PPC64]

available rop chain generators:
  execve (execve[=<cmd>], default /bin/sh) [Linux x86]
  mprotect  (mprotect=<address>:<size>) [Linux x86]

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         Print version
  --console             Starts interactive commandline
  -f <file>, --file <file>
                        The file to load
  -a <arch>, --arch <arch>
                        The architecture of the loaded file
  -i, --info            Shows file header [ELF/PE/Mach-O]
  -e                    Shows EntryPoint
  --imagebase           Shows ImageBase [ELF/PE/Mach-O]
  -c, --dllcharacteristics
                        Shows DllCharacteristics [PE]
  -s, --sections        Shows file sections [ELF/PE/Mach-O]
  -S, --segments        Shows file segments [ELF/Mach-O]
  --imports             Shows imports [ELF/PE]
  --symbols             Shows symbols [ELF]
  --set <option>        Sets options. Available options: aslr nx
  --unset <option>      Unsets options. Available options: aslr nx
  -I <imagebase>        Uses this imagebase for gadgets
  -p, --ppr             Searches for 'pop reg; pop reg; ret' instructions
                        [only x86/x86_64]
  -j <reg>, --jmp <reg>
                        Searches for 'jmp reg' instructions (-j reg[,reg...])
                        [only x86/x86_64]
  --depth <n bytes>     Specifies the depth of search (default: 10)
  --search <regex>      Searches for gadgets
  --quality <quality>   The quality for gadgets which are found by search (1 =
                        best)
  --filter <regex>      Filters gadgets
  --opcode <opcode>     Searches for opcodes
  --type <type>         Sets the type of gadgets [rop, jop, all] (default:
                        all)
  --detail              Prints gadgets more detailed
  --chain <generator>   Generates a ropchain [generator=parameter]
  -b <badbytes>, --badbytes <badbytes>
                        Set bytes which should not contains in gadgets
  --nocolor             Disables colored output
