Paste the buy button on the page where you sell. Pick which ways your buyers can pay: card, crypto, or by mail. We run every part that has to live on a server, so your site doesn't have to, and neither do you.
If your site is the only thing handling a payment, these jobs go undone. Coin Moebius does them so you don't have to think about them.
Anyone on the internet can send a fake "they just paid!" message to your site if nothing's checking. Real notifications from Stripe or NOWPayments arrive with a digital stamp only a server can read. We read it, so a faked notice never reaches you and you never ship a product for an order nobody paid for.
A card charges in two seconds. Crypto takes a few minutes. A mailed envelope of cash takes a few days. Something has to be awake and watching when each answer arrives, long after the buyer closed their browser tab.
Once the money is in, we send the buyer to your success page, log the sale in your dashboard, and let your page know the payment is done. Every method ends here the same way, no matter how it started.
Five questions any payment tool should answer plainly. Coin Moebius is the only row that gets all five right.
| Product | Ways to pay | Who holds the money | Works on a page with no back-end | One setup for every way to pay | Can you walk away |
|---|---|---|---|---|---|
| Coin Moebius | Cards, crypto, and pay-by-mail in one picker | Your providers. Never us. | Yes | Yes. Same setup whether they pay by card, crypto, or mail. | Yes. The code is open-source. Run it yourself or pay a developer to. |
| Stripe Buy Button | Cards only | Stripe (your account) | Yes | N/A. Only one method. | No. Stripe-locked. |
| Lemon Squeezy, Polar, Paddle | Cards (a few add PayPal) | They do. They're the merchant of record. | Yes | N/A. Only one method. | No. They own the buyer relationship. |
| Snipcart, Foxy.io | Many card gateways | Your gateway. They take a fee on top. | Yes | No. A different gateway hook per integration. | No. Their cart format. |
| Helio | Crypto only | They do | Yes | N/A. Only one method. | No. Locked to their wallet flow. |
| BTCPay Server, Bitcart | Crypto only | You do. Non-custodial by design. | No. You run their server yourself. | N/A. Only one method. | Yes. Open-source, yours to keep. |
| Hyperswitch (and other orchestrators) | Many card processors | Your processors | No. Needs your own back-end. | Yes, across card processors. | Yes. Open-source. |
That's the matrix. The point isn't any single yes. You need every one of those answers in place to sell things from a website you don't run a server for, and Coin Moebius is the only row that has all five.
Six things the alternatives can't do because they got at least one of those answers wrong.
Same button on your page, whichever way the buyer chooses. Card via Stripe, crypto via NOWPayments, or pay by mail. You decide which to turn on; your buyer sees only the options you picked. Adding a new way later doesn't change the button on your page.
Cash in an envelope, a personal check, a money order, or a stack of Goldbacks. Your buyer gets on-screen mailing instructions and a reference code; the sale appears in your dashboard when you mark the envelope as received. Same picker, same dashboard, same plan as cards.
Payments settle into your Stripe account, your NOWPayments account, or your mailbox. We aren't in the middle of that flow. If we shut down tomorrow there is nothing of yours we could lose, and we can't be the reason your account gets frozen because we never had your money in the first place.
Carrd, Webflow, Framer, Squarespace, Astro, Hugo, plain HTML, even a Notion page. If your site lets you paste a few lines of HTML on a page, the buy button works there. No platform extension, no framework rewrite, no migrating your site to a checkout product's preferred stack.
Mark a product as Buyer-priced and your buyer picks the amount. Same button, same dashboard, same site. Tip jars, donations, pay-what-you-want releases, and "name your price" sales sit next to your fixed-price products in one catalog.
A hundred transactions every month, every month, with no trial countdown, no card on file, and no sales call. Pro is $10/month when one of your products takes off, with no per-transaction fee on top of what your provider already takes.
The thing that makes Coin Moebius work is published in the open. If our company goes away, your buy button doesn't have to.
The open-source SDK is the part that does the actual work. It draws the buy button, checks that a real payment is real, and tells your page when the money is in. The paid Cloud is a hosted home for that code, your transactions dashboard, and a vault for the keys that connect it to your Stripe and crypto accounts. Convenience, not lock-in.
If we shut down tomorrow, or you'd rather host the buy button yourself, the SDK is on GitHub and the contract is the one we use today. Point it at your own server and your site keeps selling things, with or without us. There is no proprietary format you'd have to escape, no buyer list of ours to fight for, and no contract keeping you here.
The docs are public. The SDK is open-source. The pricing is on one page.
