Free to run yourself. Fair to let us.
The engine is open source and always will be. Cloud is the same code with managed infrastructure, edge checkout, and someone else on call.

Pricing questions
What people ask before choosing a plan. Anything else, write to us.
hello@mercury.devWhat does Mercury actually do?
Mercury is the back end of a store: the catalog, cart, checkout, orders, inventory, customers, and payouts, exposed through one API and an admin. You bring the storefront, or start from one of ours.
Is it really open source?
Yes. The whole engine is Apache 2.0 on GitHub, including checkout and the admin. Cloud is the same code, run and backed up by us.
How long does a migration take?
Most stores under fifty thousand SKUs cut over in two to six weeks. The importer keeps order history, customers, gift cards, and redirects so search rankings survive.
Which payment providers are supported?
Stripe, Adyen, Braintree, Mollie, PayPal, and any provider with a card-tokenization API through the adapter interface. Apple Pay and Google Pay work out of the box.
Can I run multiple stores from one install?
One Mercury install serves any number of stores, each with its own domain, currency, catalog, and team, sharing customers and stock if you want them to.
What happens to my data if I leave Cloud?
You export a complete database dump and media archive from the admin and run it on your own servers. Same code, no lock-in.
