## What it is
Mailchimp Open Commerce (formerly Reaction Commerce) is an API-first, headless e-commerce platform built with Node.js, MongoDB, React, and GraphQL, extensible through a plugin system. It supports products with variants, inventory, shipping, taxes, fulfillment, and multi-tenant shops, deployable via Docker and Kubernetes. The project has been discontinued.

## Use cases
- build a headless e-commerce storefront with a GraphQL API
- self-host a customizable online shop
- run a multi-tenant marketplace platform
- manage products, inventory, and orders from an admin dashboard
- extend commerce functionality with custom plugins
- deploy a scalable commerce stack on Kubernetes

## When to choose
- you need a fully open-source, API-first commerce backend you can self-host
- you want deep customization via a plugin architecture
- you need multi-shop or multi-tenant commerce support
- your stack is Node.js, MongoDB, and GraphQL

## When to avoid
- you want actively maintained software with ongoing support and security patches
- you need a turnkey hosted store with minimal development effort
- you prefer a non-GPL license for commercial distribution
- you rely on community plugins, since the ecosystem is no longer maintained
