Ah interesting. It seems to be no better than the Perl one though, except not requiring Perl. It's still a static SVG.

It's not a static SVG though. The SVG supports interactivity. You can click on each element to zoom in and it even has a search feature.

Ah really? Their example here doesn't do that: https://github.com/jonhoo/inferno/blob/main/tests/data/flame...

But even so, pprof's is better. (You'll have to try it or take my word for it; they don't seem to have a demo anywhere unfortunately.)

When you hover a function it highlights all the other calls to that function (in different stacks), and if you click it it shows all the calls to and from that function in all stacks with two-sided flame graph.

The one at https://github.com/flamegraph-rs/flamegraph/blob/main/exampl... supports both zooming and search.

Ah I see. Yeah pprof is significantly superior.
