Announcing Mercur 1.0: Marketplace Platform without Limits

After months of development, testing, and close collaboration with early adopters, we’re excited to announce the official release of Mercur 1.0 - the first truly limitless marketplace platform. Version 1.0 is fully open source and ready to be self-hosted, giving you full control over infrastructure, customizations, and data.

With this version, Mercur is production-ready for B2C marketplaces. The first complete version includes a vendor system, admin panel, and a fully built B2C Storefront. Support for B2B use cases is actively in development and coming soon.

Mercur extends Medusa with ready-to-use marketplace logic and creates high-quality experiences for both shoppers, vendors and admins while maintaining complete control over your marketplace's future.

Let’s break down what’s new and what makes Mercur 1.0 a game-changer for your marketplace.
