I read the title and initially assumed this was about web serials[1] in the sense of serialized fiction posted to the internet.

This is great, before this you had to use Chrome for any sort of serial interface to gadgets. (or some weird firefox plugin that required some other running process.)

WebUSB next? I would like to be able to configure my keyboard but it can only be done via their website which requires WebUSB.
