You want to develop something for a social networking app? And if you want to do that without worrying about hitting rate limits and API call limits, I honestly dont know if there is anything other that Nostr with that comfort level. Spin up your own relay, use it as "Test net". Worry free!!! #Nostr

Testing for this note… we made seven attempts to⚡zap this note, using your lightning address starting with "thebetelgeuse", over a period of 11 minutes. Two of the zaps were successful, but five of the zaps failed. Average zap time was 3611ms (3.6 seconds). We consider this zap time slow... generally, zaps should complete in under two seconds. (Other Nostr users might think your zaps are broken, might not zap you again.) We recommend you receive zaps with a well-connected, cloud-based Lightning node to reduce inbound zap latency.
I am using Alby! not sure why it is slow!
