Coin Moebius
Observatory · I

Sell anything from any page you made.

Paste the buy button on the page you sell from. Your buyers pay the way they want, through the payment accounts you already use. We run everything that has to happen on a server, so you don't need one.

Who is it for?

Five ways people get paid with Coin Moebius. Start where you fit.

For creatorsSell films, music, art, and downloads from the page you already have.For causesTake donations and dues with no cut taken, one-time or monthly.For shopsSell physical goods, with shipping collected through your own provider.For developersPoint every payment rail at one webhook and build on the normalized event.For foundersCharge subscriptions without building any of the billing yourself.

How it works

Three steps from "I made a page" to "I just got paid."

I

Paste the buy button

A few lines of HTML on whatever page sells your thing. Paste it as many times as you have things to sell.

II

Your buyer picks how to pay

Card, crypto, or pay-by-mail. The picker shows only the rails you turned on. They never leave the flow.

III

We confirm and log it

We do the part that needs a server: verify the payment, log the transaction, send the buyer to your success page. You see it in the dashboard.

See it live

This button is real, in demo mode. Click it, choose how to pay, and walk through the exact experience your buyers will have. No actual charge happens.

A fixed-price button — the same way your real buyers will complete a purchase.

Learn how to customize it

Why not build it yourself?

You could. Some people do. Here is everything that involves, and everything we handle instead.

Doing it yourself

  • Write a payment webhook, then keep a server running to catch every sale.
  • Prove each "they paid" message is real, separately for every provider.
  • Sit and wait for the slow ones. Crypto clears in minutes, mailed cash in days.
  • Log every sale and reconcile it against each provider by hand.
  • Build the whole thing again for each new way you want to get paid.

Your code, your server, your 2 a.m. call when it breaks.

With Coin Moebius

  • We run all of that for you. Nothing to set up, nothing to keep online.
  • We make sure every payment is real before it reaches you, so no one can fake an order.
  • We keep watch day and night. The moment the money arrives, your buyer lands on your thank-you page.
  • Every sale shows up in one simple list you can read at a glance.
  • Want to add a new way to pay? Turn it on with a click.

You add one button to your page. We take care of everything behind it.

Why this is different

Seven things we do because the alternatives don't.

One picker, every way to take money

Cards via Stripe, PayPal, Authorize.Net, or Square. Crypto via NOWPayments. Pay-by-mail for cash, checks, or Goldbacks. Same picker, same dashboard, same plan. Turn rails on and off whenever.See the full provider list.

Strict Mode: the price you set is what they pay

Prices live in the dashboard. Editing the page in a browser changes what's shown but not what gets charged.

Tip jars and pay-what-you-want, too

Mark a product as buyer-priced and the buyer picks the amount. Same button, no extra wiring. Built for donations, tips, and pay-what-you-feel.

Subscriptions: one button, recurring charges

Mark a product as Monthly or Annual. The same button handles renewals. Stripe, PayPal, and the card networks manage the recurring flow; we relay the events.

You can leave whenever

The whole thing runs on an open-source SDK. If we go away, or you just want out, you point it at your own server and your site keeps working. We can't lock you in.

We never touch your money

Payments settle into the provider accounts you already hold. Coin Moebius is software that connects them, not a bank and not a processor, so we never take custody of your funds. Our copy of the data is minimal by design.

The less we store, the less we lose

No buyer emails, addresses, or raw payment data. Just the amount, the status, and the provider's event id. IPs are hashed before storage.

Works on the page you already have

If your site lets you paste a few lines of HTML on a page, the buy button works there. No plugin, no platform extension, no framework rewrite.

  • Astro
  • Hugo
  • Eleventy
  • Jekyll
  • plain HTML
  • Webflow
  • Carrd
  • Framer
  • Squarespace
  • WordPress
  • Ghost
  • Notion sites

Anywhere else that takes an HTML embed works too. The dashboard shows you the exact lines to paste, with your project's id already filled in.

For developers, the SDK is the whole product

The buy button is the easy way. The hard way is also fine.

SDK

The open-source SDK ships every provider, every signature check, every status code. Build your own checkout UI on top of our hosted webhook and /status endpoint, or run the whole thing on your own server and skip us entirely.

The Cloud is the convenience layer. The SDK is the product. We maintain both, and we use the SDK ourselves to bill for the Cloud, so an outage in our own integration breaks our own checkout first.

Free tier: 150 transactions per month, no card required. Pro is $24/month when you scale.
