Is stride really free?

I've been hearing a lot about Stride, and how it's a great tool for managing business expenses and invoices. But one question that keeps popping up in my mind is, is Stride really free? I mean, there are so many other financial management tools out there that charge a monthly or annual fee. So, can you tell me more about Stride's pricing model? Are there any hidden costs or fees that I should be aware of? I want to make sure that I'm making the right decision for my business, and that Stride truly is a cost-effective solution for managing my finances.
