Mercur is an open-source, headless multi-vendor marketplace platform built on top of the Medusa commerce engine. It provides vendor onboarding, multi-vendor catalogs and offers, commissions, order splitting, and automated payouts, with a storefront, vendor panel, and admin console.

Use cases

• launch a multi-vendor marketplace without GMV fees
• build a B2B marketplace with vendor onboarding and KYC
• self-host a Mirakl alternative on my own infrastructure
• split customer orders across sellers and automate vendor payouts
• add a marketplace layer on top of Medusa commerce
• manage vendor commissions, offers, and a buy box engine

When to choose

• you want to own the source and self-host your marketplace
• you need multi-vendor logic like offers, commissions, and payouts out of the box
• you want a headless, TypeScript, API-first platform extensible without forking
• you want to avoid SaaS transaction fees or building a marketplace engine from scratch

When to avoid

• you need a simple single-seller storefront without marketplace features
• you prefer a fully managed hosted SaaS with no infrastructure to run
• your team cannot operate Node.js/PostgreSQL infrastructure
• you need a non-TypeScript stack
