## What it is
BTCPay Server is a free, open-source, self-hosted Bitcoin payment processor written in C#. It lets merchants accept direct, non-custodial Bitcoin and Lightning Network payments with no fees or intermediaries, and includes built-in apps for point-of-sale, invoicing, crowdfunding, and payment buttons.

## Use cases
- accept bitcoin payments on my online store without a third party
- self-host a non-custodial bitcoin payment gateway
- integrate lightning network payments into e-commerce
- create a point-of-sale app for a physical store
- run a crowdfunding campaign accepting bitcoin
- generate bitcoin invoices and export them for accounting
- embed a bitcoin tipping button on my website

## When to choose
- you want fee-free, KYC-free, non-custodial bitcoin payments
- you need full control over funds and private keys
- you want self-hosted infrastructure with privacy features like Tor

## When to avoid
