In their own words
MarketplaceKit
MarketplaceKit is a platform for building marketplaces for products, rentals, bookings, or listings where buyers contact sellers. Owners can charge transaction commissions, listing fees, and membership fees. Product listings can have multiple variants; bookings can use dates, nights, or time slots. The platform includes direct messaging, listing moderation, and controls for approving members before they post or browse. Users can upload images, video, and PDFs, with generated thumbnails and AI-powered image cropping. To shape a marketplace, owners can use custom HTML, CSS, snippets, and a homepage page builder. MarketplaceKit is available on the web and through self-hosting, with Android and iOS apps buildable using its API. Integrations listed include Stripe, MailChimp, Paystack, InstaMojo, and offline payments. The free Community Edition is self-hosted and lighter than the hosted service, with no customer support. Hosted plans start at $15/month; hosted customers receive daily database backups downloadable from the browser.
Mercur
Mercur is an open-source, headless platform for building multi-vendor marketplaces on Medusa v2. Its MIT-licensed core covers vendor management, catalogs, offers, split orders, commissions, and payouts, including vendor payouts through Stripe Connect. A typed REST API spans admin, vendor, and storefront scopes. Teams can deploy Mercur in their own cloud, on-premise, or an air-gapped environment; managed Mercur Cloud hosting is separate. Open Source lists HTTP-only session authentication, per-vendor data isolation, and TLS in transit at the deployment layer. Enterprise adds financial settlement, BuyBox, vendor integrations, and enterprise access controls, plus Shopify and Magento / Adobe Commerce connectors. Enterprise support includes a Platform Specialist, dedicated Slack and email, architectural guidance, and an SLA for maintained-code defects and incidents. Enterprise licensing is quoted. Connecting an organization’s ERP, PIM, OMS, or custom feeds and building the marketplace require separate implementation work.
