Ultimately IRHydra was always just a stopgap solution I created out of wooden sticks and duct tape. I always hoped that one day DevTools will be able to display all this information and more. Unfortunately this has not yet happened.
If you benefited from IRHydra in the past and think you will need a similar tool for modern V8 then please contact V8 Team and let them know your needs and requirements. A tool like IRHydra must be deeply integrated with the VM it targets to provide the best experience. Which means it should preferrably be maintained by the people who work on that VM.
