Unix generally comes with diff preinstalled, if not, it should be easy to install (https://xkcd.com/1654/). If everything else fails, you can install from source.

On Windows, TortoiseSVN comes with TortoiseMerge, a very nice tool that can not only diff two files, but can also merge two versions of a file. A handy little trick is that you can edit files while using TortoiseMerge in diff mode. TortoiseGit comes with a very similar tool named TortoiseGitMerge. I never used the latter, but I guess it's the same tool except for the interface to the VCS (SVN vs. git).
