Is eclipse free?

Excuse me, could you clarify something for me? I've been hearing about Eclipse as a software development tool, and I'm wondering if it's available for free. Is Eclipse completely free to download and use, or does it come with any costs associated with it? Additionally, are there any limitations or restrictions on the free version that I should be aware of? I'm just starting out in software development and would like to make sure I'm making the right choice for my needs. Thank you in advance for your help!
