Use clovyr.app's free plan (7-day free trial) for testing BTCPayServer. Or maybe don't as Clovyr doesn't update BTCPayServer often. Use Voltage Cloud only even for testing because I had a webhook error as Clovyr was using old BTCPayServer version. Or use kyun host to deploy your own BTCPayServer on a Linux VPS for $15/month.
After testing, you can use Lunanode or Voltage Cloud's hosted BTCPayServer Plan for $8/month or buy a VPS from Kyun Host ($16/month) to self-host it yourself using btcpayserver-docker.
Use Sparrow Wallet to test Bitcoin Payments using testnet with bitcoin testnet faucet.
