Shopify Plus vs Saleor

	Shopify	Saleor
Payments	Limited flexibility using various payment gateways simultaneously; extra charge applies when using external payment providers.	Saleor provides native payment integrations with popular providers and API to create any payment logic or integrations without limits or fees. Ideal for payment orchestration solutions.
Checkout	Provided by Shopify with customization limits. Extending checkout functionality requires specialized plugins and SDK, which have various limits on network requests, memory consumption, etc. Some checkout flows are not possible.	Fully headless, use APIs to build checkout on any type of device or checkout flow.
Multi-market	Limited multi-market customization and localization sometimes requires several backend instances to adapt.	All objects and settings are adjustable per market; a single backend instance can be used for multiple regions and business models (B2C, B2B, etc).
Open-source	Proprietary backend and most apps. The design system for building apps is limited to use with Shopify.	BSD-3-Clause license. Commercially friendly license for backend, frontend, and apps.
GraphQL	Storefront and Admin functionality. The extension of Checkout is achieved with proprietary SDK.	GraphQL native
Headless	Headless admin and storefront are possible, but not the Checkout.	Headless only
API rate limits	Admin API comes with request limits, which can be a source of errors for integrations, automation, or larger team collaborations. There are also limits for customer account API and payment apps.	Unlimited
Extensibility	Checkout is extended via Shopify functions with various restrictions and is limited to specific programming languages.	Fully extensible via API
Apps	One of the largest 3rd party plug-and-play App Stores in commerce.	Saleor does not provide support for 3rd party extensions to guarantee the privacy, security, and reliability of the platform. Businesses that wish to purchase extensions can do so via Saleor partners.
