Why we built it
Mercury started in 2023 as the back end of one store. The founders had run commerce engineering at two platforms and watched the same thing happen at both: the store the customer paid for was never really theirs. Every feature was an app, every app owned a slice of the data, and leaving meant starting over.
So they wrote the engine they wished they could have licensed — orders and stock as ledgers, checkout as a single hosted page, and every feature behind one public API — and released it under Apache 2.0. Cloud came a year later, for the teams who wanted the same code without the pager.
Today Mercury runs stores in forty countries, from a ceramics studio that sells out in minutes to a marketplace with sixty producers behind one checkout. The engine is still the engine. Nobody has to leave.
