Valvin, currently it's a limited "slowly expanding" trial until things are fully up to steam and the whole thing can be opened. But basically it's a small size hands-free hosted Matrix server costing $10 for a maximum of 5 monthly active users, with extra users costing $1.5/mo. If you want an easy no hassle personal or small team Matrix server then this is the easiest solution for sure + of course you can always request your data later should you want to host one yourself.

There is a sign-up for trial at https://www.modular.im/services/register-interest-small where you can leave your interest.
