When I think about Requestly, I think it fits one of the key aspects of selling a product - show rather than tell. Requestly gives us the power to show the customers our solution on their own websites rather than some demo environment which they're not familiar with.

Requestly has eliminated the complexity of testing environments for us, allowing our development team to directly test API and JS snippet changes on customer apps and sites without the need for deployment cycles.

Requestly not just made it easier for us to develop, test & debug our code on our customer sites but It also helps us do engaging product demos to our prospective clients.

Requestly is a game-changer for us. It started with one person and now the entire team uses Requestly to test our Staging code on production customers & non-customer sites. We more confidently ship product updates now.

I'm a big fan of Requestly, and use it on a daily basis as a QA Engineer. It removes the need to use Charles pretty often, which is always nice. Not that Charles wouldn't do the job, it's just super convenient to not need to open a separate application to do the same things -- instead I can just use Requestly directly in Chrome

Requestly is awesome. I used to use Charles proxy in my day to day work but it always messed with my wifi. I haven't had any issues with Requestly. Requestly's UI is amazing too and great to work in

Senior Product Manager at Metrical

Requestly has been a lifesaver for testing our product on our customers websites. Everyone's stage sites are a hot mess of half finished dev projects, but Requestly allows us to mock up stage sites in seconds that better reflect the live sites!
