LaunchPass next to GlassRelay
LaunchPass runs paid Slack and Telegram communities as well as Discord. We only do Discord, or a standalone storefront if you have no server at all, so if your people are on Slack there's nothing here for you.
On Discord the card charge runs through your own Stripe either way. The difference is what sits next to the card: we take PayPal too, which lands the members who won't type a card number, and in our own Discord that's a real slice of them. LaunchPass bills a monthly plan plus a share of each sale, at the rates on launchpass.com. We charge no fee on your sales at all.
