icon

Srijan Bhatnagar (ID: 000000a30a2c7bd5) Voted 5 β˜… - Updated 06/05/2024 Just loved the way Requestly saved several person hours for our dev team by allowing us to redirect and intercept requests. The simple yet efficient rules allowed us to seamlessly redirect requests from a single staging front-end server to local backend servers. This meant that our devs didn't need to build or run the front-end server locally when focusing on backend tasks.

Arthur Engelhard (ID: 0000001ba5a4760b) Voted 5 β˜… - Updated 04/10/2024 Love using Requestly to swap version of Adobe Launch from Prod to Staging and Dev. And also blocking various martech scripts to analyze their impacts on CWV.
