LNbits

LNbits is a free, open-source Bitcoin Lightning wallet and accounts system that serves as a flexible platform for building payment applications. Rather than a managed payment processor, it's a self-hosted layer that sits on top of any Lightning backend like LND, Core Lightning or a hosted node. Out of the box it covers point of sale, payment links, checkout buttons, paywalls and much more. Merchants and developers can run it on their own infrastructure at zero platform cost, with no transaction fees beyond network fees. A hosted SaaS option is also available at lnbits.com for those who don't want to self-host.
