Fluctum is an open-source Medusa Starter for teams building commerce with real-time, market-driven pricing. Start with a complete commerce foundation instead of building a shop from scratch, then customize the code, pricing logic, integrations, and infrastructure to fit your business. Built on Medusa, Fluctum gives teams full ownership and control to run commerce on their own rules.
Hi!
I’m software engineer at u11d, and we built Fluctum after seeing how much work it takes to build commerce for products with market-driven prices.
We wanted to create a strong starting point rather than another black-box SaaS: a complete Medusa Starter that teams can customize, integrate, deploy, and ultimately own.
The first use case is bullion, but the architecture is intentionally broader. You can adapt the pricing logic, connect your own data sources, integrate existing systems, and shape the commerce experience around your business.
The goal is simple: give teams a solid foundation so they don't have to build a commerce platform from scratch, while keeping the flexibility and control to make it their own.
