What it does
Solidus is a free ecommerce framework built with Ruby on Rails. Its components cover the commerce core, administration and REST API, with a starter storefront or a custom frontend. Solidus Cloud provides a separate managed route priced around resources.
Solidus can be assembled around the parts a development team needs. Separate Ruby libraries provide the commerce core, administration and REST API. The starter storefront supplies a starting design, while a custom frontend can use a different technology.
For a subscription-box business, the platform's subscription engine sits alongside promotions and localization. The development work is to connect the recurring offer with the merchant's actual fulfilment process. Solidus began as a Spree fork and has its own maintained project and contributor community.
Starting a Rails implementation
The installation guide supports adding Solidus to a new or existing Rails application. Its installer asks whether to include the starter storefront and which payment integration to use. PayPal, Stripe and Braintree are offered, or the team can defer that choice. Each selected connector has its own configuration instructions.
The installed store has an /admin interface using administrator credentials. Merchant settings live alongside the application's configuration; the generated initializer includes defaults such as currency and API authentication. This is an implementation framework, so a developer needs to configure and operate the application.
Free software and managed service
The BSD-style licence permits continued use and modification without a software fee, subject to its notice conditions. Self-hosting still needs application hosting, database operation and maintenance.
Solidus Cloud is a commercial alternative with resource-based pricing rather than a revenue percentage. Its Enterprise offering includes phone and email support and managed infrastructure. The public overview does not give a numeric project price. Compare the required development and operating work as well as the licence when choosing a deployment route.
