Ghidra excels because it is extremely abstract, so new processors can be added at will and automatically have a decompiler, control flow tracing, mostly working assembler, and emulation.
IDA excels because it has been developed for a gazillion years against patterns found in common binaries and has an extremely fast, ergonomic UI and an awesome debugger.
For UI driven reversing against anything that runs on an OS I generally prefer IDA, for anything below that I’m 50/50 on Ghidra, and for anything where IDA doesn’t have a decompiler, Ghidra wins by default.
For plugin development or automated reversing (even pre LLMs, stuff like pattern matching scripts or little evaluators) Ghidra offers a ton of power since you can basically execute the underlying program using PCode, but the APIs are clunky and until recently you really needed to be using Java.
when i try to expand their faq, it seem to try an open a (presumabl) malicious link , i wont paste the link here just in case it is really malicious
I wonder what is the purpose of ghidralite dot com. SEO spam? Are they building trust and then will swap out the Download button with a poisoned binary.
Ghidra takes a program and unravels the machine code back into assembly and thus, something resembling C code. Allowing you to change behavior.
Cheat Engine doesn’t modify the binary. Ghidra can.
They create executables, which contain encrypted binary data. Then, when the executable runs, it decodes the encrypted data and pipes it into "sh".
The security is delusional here - the password is hard coded in the executable. It was something like "VIVOTEK Inc.".
Ghidra was able to create the C code and I was able to extract also the binary data to a file (which is essentially the bash script).
Ghidra is the better tool if you're dealing with exotic architectures, even ones that you need to implement support for yourself. That's because any architecture that you have a full SLEIGH definition for will get decompilation output for free. It might not be the best decompiler out there, sure, but for some architectures it's the only decompiler available.
Both are generally shit UX wise and take time to learn. I've mostly switched from IDA to Ghidra a while back which felt like pulling teeth. Now when I sometimes go back to IDA it feels like pulling teeth.
- AVR
- Z80
- HC08
- 8051
- Tricore
- Xtensa
- WebAssembly
- Apple/Samsung S5L87xx NAND controller command sequencer VLIW (custom SLEIGH)
It's also not about lack of support, but the fact that you have to pay extra for every single decompiler. This sucks if you're analyzing a wide variety of targets because of the kind of work you do.
IDA also struggles with disasm for Harvard architectures which tend to make up a bulk of what I analyze - it's all faked around synthetic relocations. Ghidra has native support for multiple address spaces.
Maybe we need to get some good cracked^Wcommunity releases of Binja so that we can all test it as thoroughly as IDA. The limited free version doesn't cut it unfortunately - if I can't test it on what I actually want to use it for, it's not a good test.
(also it doesn't have collaborative analysis in anything but the 'call us' enterprise plan)
(not if you're only doing x86/ARM stuff, though)
For embedded IDA is very ergonomic still, but since it’s not abstract in the way Ghidra is, the decompiler only works on select platforms.
Ghidra’s architecture lends itself to really powerful automation tricks since you can basically step through the program from your plugin without having an actual debug target, no matter the architecture. With the rise of LLMs, this is a big edge for Ghidra as it’s more flexible and easier to hook into to build tools.
The overall Ghidra plugin programming story has been catching up; it’s always been more modular than IDA but in the past it was too Java oriented to be fun for most people, but the Python bindings are a lot better now. IDA scripting has been quite good for a long time so there’s a good corpus of plugins out there too.
I guess one issue I have is that I don't have good ideas of fun projects, and that's probably something I need to actually get the motivation to learn. I can find a "hello world", that's easy, but it won't help me get an idea of what I could reverse engineer in my life.
For instance I have a smartspeaker that I would like to hack (being able to run my own software on it, for fun), but I don't know if it is a good candidate for reverse engineering... I guess I would first need to find a security flaw in order to access the OS? Or flash my own OS (hoping that it's a Linux running there), but then I would probably want to extract binary blobs that work with the buttons and the actual speaker?
The book is designed for beginner and advance users.
So for the second thing, pulling the data off chips like that typically involves some specialized hardware, and you have to potentially deal with a bunch of cryptographic safeguards to read from the chip’s memory. Not impossible though, and there are not always good safeguards, but might be worth checking out some simpler programs and working up to it, or learning some basic hardware hacking to get an idea of how that process works.
Being able to hook Claude code up to this has made reversing way more productive. Highly recommend!
I've used IDA, Ghidra, and Binary Ninja a lot over the years. At this point I much prefer Binary Ninja for the task of building up an understanding of large binaries with many thousands of types and functions. It also doesn't hurt that its UI/UX feel like something out of this century, and it's very easy to automate using Python scripts.

I once tried learning how to RE with radare2 but got very frustrated by frequent project file corruption (meaning radare2 could no longer open it). The way these project files work(ed?) in radare2 at the time was that it just saved all the commands you executed, instead of the state. This was brittle, in my experience.
I don't have a lot of free time, so I have to leave projects for long periods of time, not being able to restart from a previous checkpoints meant I never actually got further.
IIUC, one of the first things Rizin did was focus on saving the actual state, and backwards/forwards-compatibility. This fact alone made me switch to Rizin. To its credit, my 3-year old project file still works!
Now for the downside: there is apparently a gap in Windows (32-bit) PE support, causing stack variables to be poorly discovered: https://github.com/rizinorg/rizin/issues/4608. I tested this on radare2, which does not have this bug. I'm hoping this gets fixed in Rizin at some point, at which point I'll continue my RE adventure. Or maybe I should give an AI reverse engineer a try... (https://news.ycombinator.com/item?id=46846101).
