  Maybe needs a neutral party comparison :) The delivery guarantees section alone doesn’t make me trust it. You can do at least once or at most once with kafka. Exactly once is mostly a lie, it depends on the downstream system: unless going back to the same system, the best you can do is at least once with idempotancy

  It’s on the NATS website and “nats” appears in the URL three times, so maybe this isn’t the most objective source.
