About
Coin Moebius is software for selling from a static site, built by The Aquarian LLC. We're the team's first customer.
Why we built this
A site we ran needed to take payments. We didn't want to run a backend to do it. The off-the-shelf options were either heavy (run a server, manage a database, verify webhook signatures, build a dashboard), or they were someone else's managed product that didn't fit the work: locked to one provider, no pay-by-mail, no real ownership of the customer relationship.
So we built it: a single buy button on the buyer's side, a single webhook URL on the merchant's side, and a dashboard in between. Then we used it to bill for itself.
About the name
Moebius was Jean Giraud, the French comics artist whose science-fiction worlds shaped the seventies and eighties. We took the name because we love that work and the ideas behind it.
The Möbius strip is a single continuous surface, an infinite loop with no start and no end. We shaped Coin Moebius the same way. One SDK connects your static site to every payment provider you turn on, and you can swap or add rails without rewriting anything. No server to run.
How the SDK and the Cloud fit together
The open-source SDK is the load-bearing piece. It's the part that handles signature verification, runs the buy button, and talks to providers. It works without our Cloud. Anyone can self-host the same code against their own server.
Coin Moebius Cloud is the convenience layer on top: a hosted webhook URL so you don't need a server, a dashboard so you don't need to write your own, and the encrypted secret store so you don't put credentials in your repo. If we shut down tomorrow, your site keeps working as long as you point the SDK somewhere else.
