I wanted to introduce an open-source Chrome extension that I had written a few months ago to analyse tracking calls (Currently supports a few vendors - with Snowplow being a star vendor).
The source code is here:
It has extra features like snapshot comparison etc which are brand new and might need some UX improvements.
Hope you find it useful - I’d love to get some feedback.
(And yes, the name is a nod to the excellent Snowplow project itself)
