Built to be useful

Free tools for actual problems.

I like building tools that fill gaps I come across in my day-to-day work. Sharing them is a way to contribute something useful to the wider digital and ecommerce community.

01 / Developer tools

Webhooked

Stop guessing what your integrations are sending. Generate an endpoint, fire a webhook and see exactly what arrived.

  • Inspect payloads, headers and query parameters
  • See incoming events in one place
  • Temporary event storage for quick debugging
