BTCPay Server enables Bitcoin and Lightning payments without a conventional processor. A guide to checkout, stores, APIs, self-hosting and security.

BTCPay Server is a free, open-source platform that lets organizations process Bitcoin payments on their own infrastructure. Instead of routing transactions through a conventional payment processor, a business operates the invoicing and checkout layer itself or selects a trusted host. Payments can go directly to its own wallet.
This makes BTCPay Server useful for online stores, digital products, international businesses, donation projects and physical retailers. It supports Bitcoin on-chain and Lightning, automates invoices and returns payment status to the store or application.
BTCPay Server is an open-source Bitcoin payment processor. It creates time-limited invoices, monitors the blockchain or Lightning backend and updates an order's status. The merchant controls infrastructure, data and wallet configuration. According to the official project description, BTCPay Server charges no processing fee; infrastructure, network and operational costs still apply.
One instance can manage multiple stores, each with its own configuration, wallet and integrations. This is useful for agencies, groups and platforms, but it requires clear separation of users, permissions and backups.
A robust integration also handles expired, underpaid, overpaid and late invoices. These exceptions must remain understandable and recoverable.
On-chain payments are suitable for larger amounts or flows that do not require confirmation within seconds. Lightning enables fast, low-value payments. BTCPay Server can expose both options in one checkout.
Lightning adds operational work: an own node needs channels, inbound liquidity, backups and monitoring. The official Lightning documentation describes own nodes and supported alternatives. A Lightning wallet is generally a hot wallet, so limits and risk models must be explicit.
BTCPay Server includes applications for practical business processes:
The official app documentation explains these modules.
Integrations are available for common commerce platforms, while custom products connect through the Greenfield REST API. It covers stores, invoices, payment methods, wallet operations and more. Webhooks notify applications about state changes. The BTCPay documentation recommends Greenfield for new custom integrations.
A reliable integration stores keys server-side, validates webhook signatures, processes events idempotently and reconciles orders regularly. Duplicate or delayed events must never cause duplicate fulfillment.
Self-hosting offers maximum control over metadata, updates, wallet connections and availability. The official Docker deployment is a sensible starting point for many production installations. Server hardening, TLS, updates, monitoring and backups remain the operator's responsibility.
A third-party host reduces administration but can see account and payment metadata and may restrict features. The official hosting documentation recommends evaluating trust, Lightning access and export options.
“Non-custodial” does not mean “maintenance-free.” Whether private keys remain exclusively with the merchant depends on the chosen wallet and Lightning configuration.
BTCPay Server focuses on complete merchant workflows: checkout, invoice status, store integrations and point of sale. LNbits is more oriented toward a modular Lightning wallet, API and extension layer. Both can coexist in the right architecture.
It fits organizations that want to accept Bitcoin and Lightning independently, control payment data and integrate payments with stores, ERP systems or internal applications. A hosted service may be enough for low volume. Business-critical processes benefit from a professionally designed, monitored and documented installation.
