Open Source Alternative

If you're on the lookout for a free, open-source alternative to a commercial application like PhotoShop, iTunes Microsoft Office, or Final Cut Pro, then you might find Open Source Alternative worth checking out.

It's nicely laid out in categories or you can search for any commercial application or by tag. If it has the application or utility listed, then it also lists any open-source alternatives and whether they run on Windows, Macintosh, Linux, Unix or Java platforms.

NB: It really only deals with open-source software so you might find that some well known freeware alternatives aren't shown here.
