Is it free?

Short answer is no.
Long answer - we believe in a fair and transparent model where every user pays a small fee for the service they use—rather than a freemium setup where some users end up subsidizing others. Most plans are billed annually, and the yearly cost is about the price of a single good cup of coffee. This reflects our philosophy - providing reliable, high-quality service equally to everyone.
