It’s been a while since I looked into Prism. I’ve used Fluid on and off since the last time I wrote on them.
Prism seems a lot more stable now, but still, Fluid comes out on top. It just completely blows Prism out of the water. So if you’re wondering which one to use (while being on a Mac, that is… not sure if there are even any other options other than Prism on Linux or Windows), just pick Fluid, and show some love to @iTod.
A Prism app has nowhere near the functionality of Fluid apps. For a normal Prism app, it seems like it behaves as a nerfed Firefox window: The preference pane seems to have been lifted from Firefox.
The apps created by Fluid seem a lot more like real applications. The “Cocoa”ness is still very much evident. The ability to assign shortcut keys is always fun, at least for the keyboard jockey in me. Dock Badges, for when applications like GMail and Google Reader to show how many unread items you have. The list goes on.
So stop looking. Just go get Fluid. And be sure to look into the Flickr pool of lickable Fluid icons.
I have been using Bazinga 4 Mac which is more like fluid but the thing I like best about it is that I can change the icon and if I share my web app online it keeps the custom icon where Fluid doesnt seem to
