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.
// 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-exportSee 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.
