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.

With Requestly, we can quickly set up "Replace Rules for switching API & Javascript Hosts" and load selective (or all) APIs from the local environment directly on higher environments. This saved us a lot of hassle, time & effort in working across environments. It's a go-to tool every day for Devs & QAs now.

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.

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!

Requestly is one-stop solution for all our needs at Wingify. Collaboration feature works like a Charm. Our devs & QAs collaborate on Requestly Rules while debugging & testing campaigns.

Requestly’s Script Modification Rule feels like magic. Me & my team actively use Requestly to test our local changes on the customers websites and ensure we deploy no-breaking changes in production.

It allows me to convert my Chrome browser into a supercharged development tool by creating advanced rules to modify the requests that the website is making. Very useful to quickly tweak API parameters and image resolutions without any code change!

I'd rate it as one of the best extensions around to boost developer productivity. Even if you're not a developer but need to navigate through loads of seemingly similar web pages, it is highly recommended with a very small learning curve.

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.

Requestly is a fantastic tool. It has made our team's life so much easier and more productive. Totally Recommend!

Thank you for making this great addon. I just checked out Requestly and indeed it is very easy to set up. It helps me customize my browsing experience entirely. Keep up the great work!
