Web Tracing Framework
The Web Tracing Framework is a set of libraries, tools, and visualizers for
the tracing and investigation of complex web applications. You spend a small
amount of time instrumenting your code and it helps you discover performance
problems, track regressions, and build buttery-smooth 60fps web apps.
This is still very much a work in progress, and not designed to work for all
applications. If you find issues when using it with your application please
contribute fixes!
For documentation, tutorials, etc see the main Web Tracing Framework website.
For a list of known issues see KNOWN_ISSUES
or the Github issues list.
Setup
See building for instructions and
testing for information on running the various tests.
