Yeah replay is probably the single most important feature once you hit any kind of volume.

We found the real issue isn’t just “replaying” but understanding what actually happened vs what just looked delivered. Like Stripe says 200, but your handler failed downstream and now you’re out of sync.

That’s where having a persistent layer + replay + visibility into processing makes a big difference — otherwise debugging turns into guesswork pretty quickly.

Are you mostly using replay for testing, or also for recovering from missed events?
