Can I use Eclipse for free?

Excuse me, I have a question regarding the use of Eclipse. I've heard that it's a popular software development environment, but I'm not sure if it's free to use. Can you clarify if Eclipse is indeed available for free, and if there are any limitations or restrictions that come with using it without a paid license? I'm interested in exploring its features and capabilities for personal projects and want to make sure I have all the necessary information before proceeding. Thank you for your time and assistance.
