The storefront – categories, search, and a catalog that spans first-party stock and third-party vendors.

The demo storefront home: search, a category bar across electronics, and a hero for new and certified-refurbished tech
2

Compare offers

Many vendors, one catalog – a listing where the same item can carry competing offers.

A deals row across the catalog – gimbal, webcam, phone, power strip, thermostat – each with its price, above a certified-renewed banner
3

BuyBox

Many vendors on the same product, one winning offer chosen up front.

A product page listing eighteen new offers from verified sellers, sorted by lowest total price including delivery, with the winner selected
4

New, used, refurbished

New, used, and refurbished conditions offered on a single product.

One product carrying both new and used offers in separate groups, each priced and sold by a verified seller
5

Split cart

One basket, multiple vendors, one checkout – shipping costed per vendor.

A cart holding two items from two sellers, each with its own seller total, under a single order summary and one checkout
6

Checkout & settlement

Logistics classes per item; at checkout the order splits and the money splits.

Checkout for two sellers and two parcels: a delivery method, estimated delivery and delivery fee per seller, resolving into one order total

Built by a team that develops marketplaces for leading brands

Mercur was built by Rigby – people who have spent 5+ years building and launching marketplaces in production. And because you own the code, working with us is a choice, not a lock-in.

The ultimate proof is the code

The engine is open source and public on GitHub; the Enterprise code is fully readable for licensees under NDA. Read the controls instead of taking them on faith.

mercur · install and extend
// one-line install over Medusa - a plugin, not a fork
module.exports = withMercur(medusaConfig)

// typed across admin · vendor · store
import { createClient } from "@mercurjs/client"
const sdk = createClient({ baseUrl: BACKEND_URL })
await sdk.vendor.products.query()

// copy a prebuilt block into your repo - you own the code
$ npx mercurjs add product-import-export

See it on your terms

The live demo is open to explore on your own. If you'd rather see it mapped to your case – your catalog, your vendors, your integrations – we'll walk you through it in 45 minutes.
