Seems legit

Im somewhat of a budding web developer and downloaded this on a wim just to see what it can do. On first impression, it appears to do exactly as it says; generate gradients with CSS. As you specify the colors you want and add/remove stops, it edits the code that it generates immediately, so you can see the changes being made. I am not particularly familiar with the intricacies of that specific code, so I cant claim its validity, but upon using it in my style sheet it brings back the same gradient on the page as was shown in the app itself. I look forward to using it to create some gradients that Ill likely use for buttons and etc. in my own sites development.

Give it a try, see how you like it!
