There's some exceptions, like Google Cloud Debugger which is getting shut down at the end of the month (although to be fair there was a long notice period). My team is pretty sad about it going away: https://cloud.google.com/debugger/docs
But, in true Google fashion, the replacement story using Firebase is a "what is wrong with you people?!" I honestly suspect that the GCP team failed to tell the Firebase team about the rug pull, and now it's "welp, good luck"
It appears based on my playing around with it that the data is actually traveling into Firebase successfully, but there is not the slightest shred of UI nor onboarding docs for "hello, I would like one cloud debugger, please"
Using debugger for the first time was actually incredible. Having a debugger attached to a live service with zero impact was such an alien feeling. What a cool piece of tech.
