BTCPay Server

BTCPay Server is a free, self-hosted, open-source cryptocurrency payment processor that allows merchants and individuals to accept Bitcoin and other cryptocurrencies without relying on third-party intermediaries. Funds are sent directly to the recipient's connected wallet, with no transaction fees charged by the platform and no account required with any external service.

The project was created in 2017 by French developer Nicolas Dorier and is maintained by a global community of open-source contributors. It is structured as a community project rather than a commercial company and is funded through grants and donations. BTCPay Server supports on-chain Bitcoin payments, the Lightning Network, and the Liquid Network, and includes a built-in wallet with hardware wallet compatibility.

The software integrates with more than 20 e-commerce platforms, including WooCommerce, Shopify, PrestaShop, and Magento. Additional tools include a point-of-sale app, crowdfunding pages, payment links, and invoice management. It can be deployed on personal hardware, cloud servers, or shared hosting providers.
