The record

Product: Mercur is an open-source, headless multi-vendor marketplace platform built on Medusa v2.
Core capabilities: The open-source engine includes vendor management, catalogs, offers, split orders, commissions, and payouts.
Enterprise modules: Enterprise adds financial settlement, BuyBox, vendor integrations, and enterprise access controls.
Integrations: Enterprise includes supported Shopify and Magento / Adobe Commerce connectors; integrations to an operator's ERP, PIM, OMS, or custom feeds are scoped separately.
Payments: Open Source supports vendor payouts via Stripe Connect.
API: Mercur provides a typed REST API across admin, vendor, and storefront scopes.
Deployment: Mercur can run on a customer's cloud, on-premise, or in an air-gapped environment; managed hosting through Mercur Cloud is purchased separately.
Security: The open-source edition lists HTTP-only session authentication, per-vendor data isolation, and TLS in transit at the deployment layer.
Compliance: The security page lists GDPR and a data processing agreement and says ISO 27001 controls are built by design for Open Source; Enterprise adds GDPR tooling and audit evidence for ISO 27001 controls.
Enterprise support: Enterprise includes a designated Platform Specialist, dedicated Slack and email channel, architectural guidance, and an SLA for defects and incidents in code Mercur maintains.
Open-source support: Open Source users receive documentation and community channels, including a public issue tracker and Discord.
Limit: Building the marketplace and connecting an organization's own ERP, PIM, OMS, or custom feeds are separate implementation work.
Intended users: Mercur describes Open Source as suited to teams that can implement, deploy, and maintain the marketplace themselves, and Enterprise for businesses needing added capabilities and platform maintenance.
Headquarters: Rzeszow, Poland
