Can you get Blender for free?

Excuse me, I'm just curious about something. I've heard about Blender, and it seems like a really powerful tool for 3D modeling and animation. I'm wondering, is it possible to get Blender for free? I mean, are there any limitations or catches if I choose to download the free version? I'm just trying to weigh my options and see if Blender is the right fit for my needs without breaking the bank.
