Self-hostedHow to self-host your Shopify Plus alternative
Taking the self-hosted route as an alternative to an enterprise tier like Shopify Plus means taking on full control of the infrastructure to work around API limits, fully customize the checkout, or run complex B2B catalogs that standardized SaaS plans aren't built to cover.

Real server requirements
Between 1GB and 2GB of RAM depending on the tool — never a single number.
The two options reflect different scaling strategies. Magento Open Source (PHP) offers a dense, years-proven monolithic engine, built for massive catalogs with complex attributes and native B2B/B2C structures — its own listing calls it "the most powerful for very large B2B/B2C catalogs," in exchange for considerably higher server requirements than the rest of the catalog's e-commerce alternatives. Saleor (Python/Django) leans into composable commerce: an API-first GraphQL architecture with event-driven webhooks, built to connect with external systems and serve multiple frontends at once — the project itself describes it as designed for very high-traffic stores, which is a design claim from the project, not a performance guarantee measured by us.
On infrastructure: Saleor runs on PostgreSQL and Redis; Magento runs on MySQL and Elasticsearch for catalog search — both engines come back up in the maintenance discussion below.
What you gain and lose versus the SaaS
The real cost of leaving an enterprise SaaS isn't the initial build, it's ongoing maintenance. You gain full sovereignty over your data and stop depending on fees tied to your plan's sales volume, but you inherit the critical responsibility for performance: your team has to configure load balancers, tune caching layers (Redis on Saleor, Elasticsearch on Magento) to survive traffic spikes like Black Friday, and secure the payment infrastructure to maintain PCI-DSS compliance — on the SaaS, Shopify carries that responsibility; here, it's yours.
