Duoload: Simplest website load comparison tool, ever

Image

This is pretty excellent tool. (Note that it cannot be used on sites that disable iframe embedding, however.)

Today I needed a quick tool to compare the loading progression (not just loading time, but also incremental rendering) of two websites, one remote and one in my localhost. Just have them side by side and see how they load relative to each other. Maybe even record the result on video and study it afterwards. That’s all. No special features, no analysis, no stats.
