Relatedly, I wanted to highlight that Dan Abramov is currently working on a refactor of ReactPerf [1] which will make the performance measurements more accurate.

Author here, interested to hear what other tools/workflows you use for debugging!

Similar to that "why did I update?" mixin, there's also https://github.com/redsunsoft/react-render-visualizer and https://github.com/spredfast/react-transform-render-visualiz.... Useful for visualization.

It's possible to pipe React profiling output into Web Tracing Framework, which gives a nice overview of the React application: https://gist.github.com/joshduck/0c35f70cdd3abf88770c
