    Dude, this sounds like an absolute lifesaver! I know exactly how soul-crushing it is to be stuck debugging Stripe webhooks at 2 AM instead of actually shipping the core product. Being able to mutate payloads and immediately replay them is the perfect way to skip that endless infrastructure rabbit hole. This is exactly the kind of practical tool that keeps the momentum alive!

    Debugging webhooks is usually a cycle of "trigger event, wait, check logs, repeat" which becomes incredibly draining when you are trying to handle complex edge cases or failed Stripe payments.

    The real friction isn't just seeing the data; it's the inability to easily reproduce a specific failure without manually triggering a whole new event in a production-like environment. By allowing developers to capture, mutate, and replay payloads with a single click, you’re essentially turning a black-box process into a controlled experiment where you can verify fixes in seconds rather than minutes.

    Are you finding that users are mainly using the code export feature for documentation, or are they using those exported pytest snippets to build out their permanent integration test suites?

The problem: every time you integrate with Stripe, GitHub, Shopify, or any webhook API, you need to see what they're actually sending. And when something breaks, you need to replay the exact request to debug it. Wha
