Overview

Floreant POS is a robust, enterprise-grade open-source Point of Sale (POS) solution architected primarily in Java, designed to provide platform independence across Windows, Linux, and macOS. Originally developed for large-scale deployments like Denny's, it has evolved into a highly modular system that addresses the 2026 market demand for local-first data ownership and zero-subscription overhead. Technically, it supports a wide array of relational databases including Apache Derby, MySQL, and PostgreSQL, ensuring scalability from single-terminal cafes to multi-location restaurant chains. Its architecture facilitates deep customization through a dedicated plugin system, supporting Kitchen Display Systems (KDS), table mapping, and complex tax jurisdictions. In the current landscape, Floreant POS serves as a critical alternative to SaaS-heavy models, offering businesses the ability to maintain operational continuity during internet outages while integrating with modern payment gateways via proprietary commercial extensions. The platform's commitment to the GPL license ensures that the core codebase remains accessible for developers to build bespoke features, while the Floreant Cloud ecosystem provides a managed bridge for businesses requiring remote reporting and centralized menu management.
