You are exactly right! The value added here is a having automatic uploads of JFR dumps, which are viewable based on machine and timespan through a web UI.

If you have it enabled in production, I assume that it requires some effort to find the right file and download it to view it on JMC? And if you want to share that view with a colleague they have to do the same. Blunders aims to make such things easier.

I've also tried to make a "better" visualization (based on flame graphs), not sure if I succeeded though :)
