Subscord, and why we still built our own
Subscord takes cards and crypto, and that's the whole comparison if a real share of your members pay from a PayPal balance. In our own Discord some of them won't type a card number into a bot's checkout page, and some have a card but PayPal is what they trust, and it doesn't much matter which: a card-only checkout doesn't make that sale. GlassRelay runs PayPal and Stripe side by side, both on your own accounts, with the member choosing at checkout.
The rest is close. The charge runs through your own Stripe, Subscord takes nothing from the sale and neither do we, and both of us bill a flat monthly tier by how many active subscribers you have (subscord.com has theirs). Coupons and free trials are on both sides. One smaller gap: we went looking for a data export on their site and came up empty, where here the full history downloads as a CSV whenever you want it.
