Solidus

Solidus is commerce as a set of engines: core, API, backend and storefront. You mount
what you need.

What you get

• Products, variants, option types and stock across locations
• Cart, checkout, orders, returns and refunds
• Promotions and tax calculation
• An admin backend
• A REST API

Mounting it

# Gemfile
gem "solidus"

bin/rails generate solidus:install

The installer mounts the storefront and the admin for you.

Be honest about the scope

This is the largest thing in the directory by a wide margin, and adopting it is a
real commitment. The reason it is here rather than in the "just use Shopify" pile is
that a Shopify store is a second system your product must sync customers, orders and
entitlements with — forever. Solidus makes an order a row in your database.
