As answered by people managing PullNotifier and HookReplay.dev.
HookReplay.dev's answer:
Still early — just launched. Currently used by indie developers and small teams debugging Stripe and Shopify integrations. No big logos yet. Focused on building a great product first.
HookReplay.dev's answer:
With ngrok, every code change means triggering another webhook. Add a log? Trigger again. Set a breakpoint? Too late, it timed out. Trigger again. With HookReplay, you trigger once. Then replay 100 times while you debug. Same webhook. Same payload. Unlimited attempts to get your code right. That's not a small difference — it's hours saved per debugging session.
HookReplay.dev's answer:
Developers who integrate third-party webhooks Stripe, Shopify, GitHub, Twilio, Paddle, etc. Basically anyone who's ever clicked "Send test webhook" more times than they'd like to admit.
HookReplay.dev's answer:
11pm on a Sunday. A customer's Stripe payment went through, but their subscription wasn't created. I needed to debug the webhook handler. Set up ngrok. Triggered a test payment. Added a log statement. Triggered again. Set a breakpoint — webhook timed out before I could step through. Triggered again. Changed the URL in Stripe because ngrok restarted. Triggered again. Three hours later, I found a typo in my event type check. I remember thinking: I just re-triggered the same webhook 40+ times. Why can't I just capture it once and replay it until I find the bug? That's the moment HookReplay was born. The tool I wished existed that night.
HookReplay.dev's answer:
ASP.NET Core for the backend, PostgreSQL for storage, WebSockets for real-time forwarding to the CLI. The CLI is built in .NET and distributed via npm — runs on macOS, Windows, and Linux. Nothing fancy. Boring tech that works.
HookReplay.dev's answer:
Three things most webhook tools don't do: 1- Replay the same webhook unlimited times 2- Edit payloads before replaying (test edge cases) 3- Keep a full history of every webhook received HookReplay does all three, plus real-time forwarding like ngrok.

The PullNotifier slack app Thoughts: We found this to be the best solution to match our needs. It sent a notification when a pull request was opened (not draft), then updated that same message with the realtime status of the app - so it... - Source: dev.to / over 2 years ago
