The complete platform to run your entire marketplace

A storefront for buyers, a vendor panel, an admin console, and integrations into your stack — open source at the core, enterprise-grade where it counts.

Open source Your infrastructure Zero GMV fees

Built on the stack your team already knows

Ownership

Multi-vendor marketplace platform you fully own

Build and customize at startup speed, with enterprise-grade governance and control.

01

Zero GMV fees

The license is your only platform cost. Your success isn't taxed.

02

Own the source

Open source, full source for licensees — an engine you can read, audit, and extend.

03

Your infrastructure

Any cloud, on-premise, or air-gapped. Data residency is your decision.

04

Built on the most popular framework

Standard JavaScript and TypeScript — any web developer can work on it, no certified specialists to hire.

05

Additive, not disruptive

Add a third-party layer without replatforming, or stand up a full marketplace from scratch.

06

No vendor lock-in

Keep the version you paid for and everything built on it — forever.

Core capabilities

80% of what a marketplace needs out of the box

The unglamorous parts are already built, tested and running in production — so your team spends its time on the 20% that makes your marketplace yours.

01

Onboard and verify vendors

Configurable applications with KYC, and approvals in one queue.

02

Compare offers from different vendors

Many vendors, one product card, the best offer up front.

03

Split the order and settle the money

One customer order becomes per-vendor orders, payouts, and a ledger that balances.

04

Run it from the command center

Approvals, disputes, and an audit trail in one place.

Proof, not promises

Future-proof technology you can verify

Every claim on this page is something you can check for yourself — read the sheet, read the architecture, read the code.

About
For developers

An API-first headless engine

A typed API across admin, vendor, and storefront, registry blocks you copy into your own repo, and an event layer you extend without forking the core.

GitHub Docs Core
0% Typed API
0+ Registry blocks
0 GMV fees 
import { createClient } from "@mercurjs/client"

const sdk = createClient({ baseUrl: BACKEND_URL })

// typed across admin · vendor · store
await sdk.vendor.products.query()
await sdk.admin.payouts.list({ status: "pending" })
await sdk.store.offers.best({ productId })
# copy a prebuilt block into your repo
$ npx mercurjs add product-import-export

✔ resolved registry block
✔ wrote src/modules/import-export/*
✔ registered routes + jobs

$ npx mercurjs dev
// react to events, in your own layer
export const config = { event: "order.placed" }

export default async ({ event }) =>
  notifyVendor(event.data.id)

// no fork, no patched core
Two ways in

Have a store or building from scratch?

Mercur adapts to where you are today — bolt it on, or build the whole thing on it.

Path 01

Add to your store

You already sell on Shopify, Magento, or your own stack — Mercur adds the marketplace layer beside it, without a replatform.

Shopify Magento Custom stack Headless
  1. 1 Keep your storefront and catalogue exactly as they are
  2. 2 Connect vendors, offers and payouts through the API
  3. 3 Go live with third-party sellers in weeks, not quarters
Add to your store
Path 02

Build standalone

Start clean. Mercur is your eCommerce and your marketplace — one engine, one data model, one deployment.

Storefront Vendor panel Admin console Payments
  1. 1 Clone the open-source core and run it locally today
  2. 2 Shape the data model and vendor flows to your market
  3. 3 Move to Enterprise when settlement and SLA matter
Build standalone
