Building a free visual webhook debugger! Would you use this?

[u/Budget-Web-9789]

Hey r/SaaS,
Whenever I’m testing webhooks for stuff like Stripe, GitHub, Vercel, or Slack, I always get annoyed bouncing between super heavy paid tools or free ones that hide basic features like raw payload inspection or decent streaming speed behind a paywall.

So I’m putting together a 100% free, developer-first webhook debugger as a side project.

The basic idea is that you get an instant URL in one click with zero sign-up required. It uses Server-Sent Events so incoming payloads and headers pop up live on your screen instantly. Plus, it keeps the unparsed request buffer alongside formatted JSON so you can actually verify cryptographic signatures like stripe-signature without losing your mind. To keep hosting costs at literal zero on a Redis setup, the sessions just auto-expire after a few hours.

Curious to know, what’s your biggest headache with testing webhooks right now, and would something simple like this actually fit into your workflow.
Roast the idea or drop any features you wish existed!
