Snail is an extension for Visual Studio Code to read and visualize results from a sampling profiler. It supports reading perf.data files written by the Linux tool perf, *.diagsession files written by the Visual Studio tool VSDiagnostics or *.etl files written by Windows tools like XPerf or the Windows Performance Recorder (WPR).
IMPORTANT: This extension is in a very early alpha state. Hence it is barely usable by anyone except it's original author.
