Congratulation! We are big fans of Requestly at Caido as we are building something somewhat similar for the infosec community (https://caido.io).

Requestly feels good and there is a lot of potential for production debugging. I particularly like the switching of API endpoint so you can use the live prod website with a local API, super useful to debug.

If your interest extends to debugging production backends you can also check out Lightrun ( https://lightrun.com ) which continues this all the way through.

Lightrun looks really interesting. Have you personally used lightrun to debug anything directly in production? I saw the video on landing page and very curious to know how it works under the hood.

Sure. It works differently for every language/platform e.g. for Java it uses a JVMTI agent. This connects to the backend server which then connects to the IDE.

This lets you send action commands to production without having a debug session into you K8S cloud.

Very Interesting that you brought K8s. In the K8s cluster, an API request could be hitting one of the multiple PODs so how does the JVMTI agent know which pod to connect to? I am definitely missing something here.

You need to install the agent in all the pods in the cluster. You can then pick a specific one or use tags to target a set of them.

So you can add a conditional snapshot (a breakpoint that doesn't break) to the set of green containers. E.g. I can add a snapshot that has a condition to only grab the data for user X. I'll get the result regardless of the container that actually handles the request.
