BTCPay Server is a free and open-source cryptocurrency payment processor which allows you to receive payments in Bitcoin and altcoins directly, with no fees, transaction cost or a middleman.
BTCPay Server is a non-custodial invoicing system which eliminates the involvement of a third-party. Payments with BTCPay Server go directly to your wallet, which increases the privacy and security. Your private keys are never uploaded to the server. There is no address re-use, since each invoice generates a new address deriving from your xpubkey.
The software is built in C# and conforms to the invoice [API of BitPay](https://bitpay.com/api). It allows for your website to be easily migrated from BitPay and configured as a self-hosted payment processor.
You can run BTCPay Server as a self-hosted solution on your own server, or use a [third-party host](https://github.com/btcpayserver/btcpayserver-doc/blob/master/ThirdPartyHosting.md).
The self-hosted solution allows you not only to attach an unlimited number of stores and use the Lightning Network but also become the payment processor for others.
Thanks to the [apps](https://github.com/btcpayserver/btcpayserver-doc/blob/master/Apps.md) built on top of it, you can use BTCPay to receive donations, start a crowdfunding campaign or have an in-store Point of Sale.
Firstly, decide if you want to host an instance yourself or use a [third-party host](https://docs.btcpayserver.org/deployment/thirdpartyhosting). If you've chosen to self-host, we documented plenty [ways to deploy BTCPay Server](https://docs.btcpayserver.org/deployment/deployment).
After successful deployment, make sure to check our [getting started](https://docs.btcpayserver.org/getting-started/registeraccount) and [walkthrough](https://docs.btcpayserver.org/btcpay-basics/walkthrough) guides. In case you would like to use Lightning Network, see [Lightning guide](https://docs.btcpayserver.org/features/lightningnetwork).
