OwnPay

OwnPay is an innovative open-source payment gateway software designed for developers, merchants, and businesses seeking full control over their payment infrastructure. Its self-hosted architecture allows organizations to build a customizable, private payment system that they fully own and manage. One of its standout features is the pioneering white-label, custom-domain checkout architecture, which enables businesses to present a seamless brand experience across multiple domains, logos, and color schemes—ensuring customers see only your brand, never OwnPay. This flexibility makes OwnPay particularly appealing for organizations that prioritize branding, security, and data sovereignty. Its open-source nature encourages community collaboration, customization, and transparency, making it a compelling choice for those who want to avoid reliance on third-party payment providers while maintaining a high degree of personalization and control.
