Fluid is developed by Todd Ditchendorf.
Once upon a time, Todd worked for a well-known Fruit Company based in Cupertino as Dashboard Engineer, developing Dashboard and Dashboard Widgets for Mac OS X Leopard.
Is Fluid Free? Yep, the basic version of Fluid is totally free… go ahead, try it out!. For $5 you can purchase a Fluid License which unlocks the following features:
Is Fluid available for Mac OS X 10.5 Leopard or earlier? No. Fluid runs on Mac OS X 10.6 Snow Leopard or later only.
Is Fluid available for PowerPC Macs? No. Fluid runs on Intel Macs only.
Is Fluid available for Macs with 32-bit processors? No. Fluid runs 64-bit only.
Can I somehow redistribute Fluid Apps I create with Fluid to friends/coworkers? I'd prefer you didn't do that. Tell your friends about Fluid, and let them try it out for themselves!
Fluid owes its existence to several open source projects listed below.
