Full control, infinite customisation, and all the tools of modern growth marketing at your fingertips.
For brands pushing past the limits of plug-and-play platforms like Shopify, Solidus offers a robust, developer-friendly alternative. Built with scalability and adaptability in mind, Solidus gives you complete ownership of your codebase, data, and customer experience—without locking you in.
Works Seamlessly With Your Existing Stack
Fully customisable to integrate with all your marketing, logistics, payment, inventory, content and operations tools.
Unmatched flexibility.
When Your Business Outgrows the Standard Stack
Shopify, Magento and similar platforms are perfect for simple shops, early stage ventures and testing ideas — but when your business needs full control, advanced customisation and room to scale, Solidus is the next step. It gives you ownership of your code, freedom to design your own processes, and the flexibility to integrate with any system. With tools like Stripe, your subscription and order data stays portable, letting you move between platforms without disruption.
- Free and open source
Solidus is free to use and fully open source. There are no licensing costs, no required subscriptions and no per transaction fees. You own your store and your code, with full visibility and control.
- Easy data migration
Solidus does not lock you in. With the right architecture, your business data can be moved to and from other platforms without downtime or disruption, including historical data and recurring revenue streams.
- Stripe and others supported
Stripe, along with other leading payment providers, works seamlessly across Solidus and Shopify. This means subscriptions and customer payment data can remain intact, ensuring that migrations do not affect cash flow or user experience.
- Flexible cloud hosting
You choose where and how to host your store. Whether on public cloud, private infrastructure or a managed service, Solidus can scale dynamically with your traffic, keeping infrastructure costs low when demand is low and scaling only when needed.
- Reusable React, Vue, Nuxt frontends
Solidus supports a decoupled architecture, allowing you to build modern frontends using frameworks like React or Vue. These interfaces can be designed to run across multiple platforms, giving you design freedom and code reusability.
- Tailored backend logic
Solidus gives you full control over every touchpoint. Create checkout flows that match your brand, introduce complex discount logic or tailor business rules to fit your operations without being limited by templates or app store constraints.
- Built on Ruby on Rails
Built on Ruby on Rails, Solidus benefits from a proven and mature development framework. It is stable, secure and loved by developers around the world, ensuring your project remains maintainable, extendable and high performing.
- Deep analytics and data access
With full access to your database and integrations like Google BigQuery, Solidus lets you track what truly matters. Build custom dashboards, connect real-time KPIs or process your data through Python for advanced insights you simply cannot get from closed platforms.
- No app store limitations
Unlike hosted platforms, Solidus does not rely on third-party apps to extend functionality. Every feature can be built directly into your codebase, giving you faster performance, full ownership and no monthly surprises.
