Requestly just works :) We are one of the paid users. We have been using Requestly to debug SendX Javascript API on our client's websites and Requestly has saved ton of debugging time for us.

Added a Requestly rule for my entire Github Pages domain so that everything resolves locally and I can import between projects I'm working on without specialized rules. Have I said how much I LOVE @RequestlyIO for dev? Def my most essential tool after a browser & a text editor!
