CPO & Co-Founder
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.
QA Engineer at Clayton Homes
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
Senior Software Engineer at Workday
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!
