File Compare Tools – Online


Need to quickly compare a couple of source code files.

I have some tools to do so on my computer but wanted to do so online.

Here are some online tools that one can use.

I got to go with Jamie Peabody’s Mergely.

It is available online as a freely available resource.

The source code is publicly availed via GitHub.

Anyone can download and use it locally or similarly avail it as a web service.

It is written in javascript and so one can get by.

The best part for me is that its interface is clean and uncluttered.
