Best Free BTCPay Server Alternative
If you're looking for the best BTCPay Server alternative to accept Bitcoin payments in your own web application and have your app automatically mark orders as paid, OpenReceive is the simplest option we know of.
BTCPay Server is powerful, but it's a whole separate server to install, run, and keep updated. OpenReceive is a free, open-source library that lives inside the app you already have. It mounts a checkout, issues Lightning invoices against a wallet you control, and calls back into your code the moment a payment settles.
Go to openreceive.org, click Copy agent directions, paste them into your AI coding agent, and let it add Bitcoin checkout to your app. Full walkthrough: Accept Bitcoin, USDT, USDC Payments on Your Website with OpenReceive.
Why OpenReceive Works Well as an Alternative​
- Works inside the app you already run. WordPress + WooCommerce, Express, Fastify, Next.js, Rails, Django, FastAPI, Laravel, and plain PHP. Your app keeps owning your orders, products, and users; OpenReceive only handles the payment. Version floors and install steps are on Accept Bitcoin payments with OpenReceive.
- Or stay on BTCPay. OpenReceive is also a plugin for BTCPay Server ≥ 2.4.4. It makes a receive-only NWC wallet the store's Lightning node, with optional USDT, USDC, ETH, and SOL swaps. No separate library, hooks, or payment tables.
- No extra server. It's a library, not a service. There's nothing to deploy alongside your app and no dashboard to babysit.
- No account, no API key, no KYC. Nothing to sign up for. Install the library and connect a wallet.
- You keep the money. Payments settle directly into a Lightning wallet you control. There's no intermediary holding funds and nobody taking a cut.
- Nothing can spend your funds. OpenReceive connects to your wallet with a receive-only Nostr Wallet Connect (NWC) code. Even a fully compromised server could only create invoices that pay you.
- Bitcoin first, other assets optional. Customers pay over Lightning by default. Any swap provider that implements the FixedFloat / Lightning-Swap API can also take USDT (Tron, Solana, Ethereum), USDC (Solana, Ethereum), SOL, or ETH. You still receive Bitcoin.
- Built for coding agents. Copy one prompt from openreceive.org and your AI coding agent does the integration.
- Free forever. MIT licensed and open source on GitHub.

Which wallet do I connect?​
OpenReceive works with any wallet that can issue a receive-only NWC code. Alby Hub and Rizful are two easy options. If you use Rizful, here's how to get the code: Get A Receive-Only NWC Code from Rizful.
When BTCPay Server Is Still the Better Choice​
BTCPay Server is still a great option if you specifically need:
- Direct on-chain Bitcoin receiving — OpenReceive settles over Lightning (with optional swaps from stablecoins), not on-chain
- A standalone merchant server — your own Bitcoin node, a hosted invoice and point-of-sale UI, and plugins, all running separately from your app
- Out-of-the-box merchant features like accounting exports and a store admin panel
If you stay on BTCPay, two Lightning backends avoid running a node: the OpenReceive plugin (BTCPay ≥ 2.4.4), or Rizful through BTCPay's Nostr plugin.
The Short Answer​
Choose OpenReceive if you want:
- Bitcoin checkout inside the app you already run (WordPress, Express, Fastify, Next.js, Rails, Django, FastAPI, Laravel, or PHP), with optional USDT, USDC, ETH, and SOL
- Or the OpenReceive plugin on a BTCPay Server you already operate
- Your app to detect and mark payments automatically
- No separate server to set up or maintain
- A one-prompt integration your coding agent can do for you
Choose BTCPay Server if you want:
- A self-hosted payments stack with direct on-chain receiving
- A standalone server with its own UI, plugins, and point-of-sale tools
For most builders who just want to accept payments in their own app and react programmatically, OpenReceive is the easier path. Jump to Accept Bitcoin, USDT, USDC Payments on Your Website with OpenReceive to get started in minutes.
