Hopper Disassembler, the reverse engineering tool that lets you disassemble, decompile and debug your
Hopper Disassembler for Mac requires macOS 10.13 or higher.
Hopper Disassembler for Linux requires Ubuntu 18.04, Arch Linux, Fedora 25 or higher, and a 64 bits processor.
Hopper is perfectly adapted to the environment. The macOS version makes full use of the Cocoa framework, and the Linux version makes use of Qt 5.
Hopper analyzes function's prologues to extract procedural information such as basic blocks and local variables.
With the Hopper SDK, you'll be able to extend Hopper's features, and even write your own file format and CPU support.
Once a procedure has been detected, Hopper displays a graphical representation of the control flow graph. You can even export a PDF.
Hopper displays the code using different representations. Take a look at the assembly, the CFG, and the pseudo-code of a procedure, all at the same time.
Most of the Hopper features can be invoked from Python scripts, giving you the ability to transform a binary in any way you want.
Hopper can use LLDB or GDB, which lets you debug and analyze the binary in a dynamic way (only for Mac and Linux hosts, not for mobile devices).
Even if Hopper can disassemble any kind of Intel executable, it does not forget its main platform. Hopper is specialized in retrieving Objective-C information in the files you analyze, like selectors, strings and messages sent.
Based on an advanced understanding of the executable Hopper can present a pseudo-code representation of the procedures found in an executable.
Edit, annotate, comment your work directly from the interactive CFG view.
This new version of Hopper is able to decode the mangled Swift names. No more cryptic names!
Use tabs to create workspaces with different representations of the file.
The analysis performed by Hopper separates code from data, memory accesses from stack variables… And to help you understand the various discovered objects, Hopper will use a different color to each of them.
Use the embedded type editor to create your own structures, unions, or enumerated types. It greatly helps the understanding of the code to use symbols, rather than raw numbers.
Find what you are looking for. The inspector panel automatically adapts its content according to the context.
Great Exploration Utility★★★★★
Fantastic tool that keeps getting better. Hopper is an affordable disassembler that supports scripting (in Python). A great tool if you ever need to take apart code for debugging, or just learning. Disassembles Mach-O, ARM, and Windows binaries.
An Incredible Contribution! ★★★★★
Hopper is an excellent modern disassembler, decompiler, and debugger. The control flow graph and pseudo code features by themselves are well worth the price. Perhaps the best aspect of Hopper is that while being a powerful disassembler, it’s also a true Mac application; it contains all the attributes you’ve come to expect from well-designed Mac applications. Hopper has assisted Mac OS X in its quest to be the developer’s choice, by providing the highest quality tools. Thank you Hopper Team, and keep up the great work.
Great disassembler! ★★★★★
Thanks a lot :) Your tool is really great. I appreciate that you made it affordable (so I can just buy it and expense it, instead of going through long procurement process for something like IDAPro, which costs way too much).
COOL! Very very easy! In about 10 minutes I explored everything of the app and loved it! Congratulations to the developer! It's really an awesome application! Hope you release an update for ARM soon! :-) - The interface is pretty fast and Mac friendly, much better than IDA. changed my life now on! :-) - Fast analysis of the application… Really really good!
It's been a long time coming for something like this on OS X, and I'm very grateful to the developer for creating such a helpful and affordable application. Before this tool came along I found myself having to do a lot of guess work, which equated to spending a lot more time analyzing projects. The developer is quick to respond to any issues, etc. and the application continues to amaze me with all the improvements with each new version. If you have a need for evaluating code, debugging, or want to understand the flow of an executable this application is a great choice.
[...] It’s an amazingly versatile and useful tool at an incredible price. Truly, it is a worthwhile investment if you want to learn more about assembler, the inner workings of code and beginning malware analysis. You can’t go wrong with this one.
Hopper is a powerful tool for disassembling executable code and inspecting the result. The ability to annotate code and even decompile it into semi-readable C-ish code makes it much easier to understand what the disassembled code is doing. It's an excellent tool and well worth the incredibly cheap price.
