awesome! we also created a zap app! you can turn off notifications (its off by default). it will pay a bit faster than zapper, but there will be a few more failures due to timeouts (we fail slow responses to optimize for speed).

Works fast indeed! So you're making lnurl calls in parallel and then also sending NWC requests in more than 1 thread?
yes and we don't go through the zap request flow (which can't be parallelized atm).
