According to the official web page, speedscope.app is “a fast, interactive web-based viewer for performance profiles”. But I believe it’s more than that! In my opinion, it’s one of the best visualization tools for performance profiles ever!
Some time ago I have implemented SpeedScopeExporter which allows exporting any .NET Trace file to a speedscope json file format. It was released as part of 2.0.34 TraceEvent library a few months ago, but so far it was not available for the end users from PerfView GUI/command line level.
