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.

After trying Requestly once, never went back to Charles. Way easier to use, convenient interface. Loved the ability to share proxy rules with the team - saved a lot of time!
