Saleor is an open-source, headless commerce platform. Its core is an API-only service built around GraphQL and extended through webhooks, apps and metadata rather than a plugin system; the dashboard and storefront are separate projects. Development teams use it to build custom storefronts and connect commerce to their own systems. It can be self-hosted from the source code, with deployment guides for Docker, Kubernetes and Linux, or used as Saleor Cloud, the vendor's SaaS offering.
Saleor Commerce was founded in Poland in 2020. The core is released under the BSD-3-Clause licence, so an organisation can run it on infrastructure of its own choosing. Saleor Cloud runs on Amazon Web Services in either a European region (Ireland, with France as fallback) or a US region (N. Virginia, with Ohio as fallback), and the documentation states that data is isolated between regions. Choosing the European region keeps Saleor Cloud data in the EU.
