OllyDbg 2.0 is a User Space level debugger that has become very popular among users all over the world. Now there are a lot of plugins written for OllyDbg, so it is a pleasure to work with it. OllyDbg has good functionality that makes it suitable for solving various tasks and researching code of any complexity. The debugger interface is fully customizable: work window background, font color and size, illumination of certain assembly instructions and much more.


- The interface consists of program code windows, registers, stack, and memory dump. The background and font colors can be set to your liking. At the top of the quick access buttons to the main functions, and the most frequent operations.


- the list of functions used in the debugged program;

- the list of string variables found in the program;

- the list of handles of the program being debugged, such as: window, buttons, checkboxes, toolbars and others;

Breakpoints. It is possible to set several breakpoints (including simultaneous ones):

- on a particular function;

- to a specific address;

- to the Windows message;

- to read from memory;

- for a memory entry;

- to access memory (read and write);

- to a certain sequence of code instructions;

It is possible to specify specific conditions for breakpoints, for example, a certain value of the specified register and much more. The log file writing function is supported:

- values in the stack are accompanied by comments, which helps to understand function arguments more easily.


- when the code is executed step by step, before each instruction the debugger prompts the current value of memory addresses, which are being operated on.

Search for values in memory:

- supports searching for ASCII and Unicode strings, as well as hex values.

The code window:

- the program code is accompanied by comments such as function names, their arguments, variable values and others.

The Olly Debuggger is awesome. It does all the standard things you want in a debugger, but it adds some nice bonuses. It doesn't matter how complex the code is, you can still use it. I also love that you can customize it - I love things like that - especially that you can change the font. I always like being able to choose my own font, so that's a great feature.

Great product traces recognizes api codes and locating routine objects is always something that is defiantly needed. Emphasizing binary code analysis is a given. Been around since 2019 . Reasonably priced

1. Olly Debugger is a powerful software for debugging applications. 2. It's very easy to use and understand, with a great user interface. 3. It provides useful information about the program's memory and registers. 4. It has a lot of useful features such as breakpoints, watchpoints and breakpoints on data access. 5. The symbol information for the functions helps to understand the code better. 6. It also supports the debugging of 64 bit applications. 7. It can be used to search for strings and binary patterns in the application's memory. 8. It can be used to disassemble code as well as examine and modify the memory. 9. I found it to be a great tool for debugging applications. 10. Olly Debugger is an invaluable tool for any programmer.

Olly Debugger is a pretty good debbuging tool. I've used it several times and it's proved to be quite reliable. It has some nice features such as breakpoints and monitering of CPU registers. It can be a bit diffcult to figure out the interface at first, but once you get the hang of it it's quite intuative. The only downside I found is that it can be slow to responding sometimes.
