I need to compare two sites say X and Y. Both X and Y are the same websites, but in Y we made some changes in a particular stage. So I need to verify the changes by comparing X and Y. Can you suggest some tools to identify the changes in my page?

  • How will you access those sites? From a browser, or internally through your network? If a program, then what OS? Price? What kind of changes do you want to detect? One page at a time, or the structure of the site as well? Please read this and edit your question.

If this is for professional development, then your version control system should diff the files for you. If you have no version control, then shame on you ;-)

In any case, if the websites were remote, you could use you could use HTTrack to download them.

Since you say that you made changes, then I presume that you already have them locally. In which case, the answer is simple.

You can pay $60 for Beyond Compare, or use a free file-compare utility, such as WinMerge, which will compare two directory trees, and tell you which files are the same, and which are different:

Then, for each file, you can compare the two versions and see the differences (even copy sections from one to the other):

I think that that will solve your problem (and, please, consider using version control in future ;-)
