    Requestly brings the power of Charles proxy in the browser. It's so simple and easy to use than Charles. Not that Charles won't do the work but Requestly is way simpler and lightweight. https://requestly.io/charles-proxy-alternative/

    If you need to debug Web apps, then Requestly is the best solution out there. Compared to Charles, Requestly has almost every functionality that Charles offers. Very user friendly and collaboration capabilities too.
