Love small practical tools with a very clear pain point.
Every USB-C cable looks the same, but some charge fast, some are slow, some handle displays, and some quietly break your setup.
WhatCable makes that visible in plain English. It basically tells you whether the cable, charger, device, or Mac port is the problem, so you don’t have to guess why your SSD is slow, your dock is acting weird, or your display refuses to work.
That is really cool, Please tell me I can use this for my iPhone and iPad as well, by any chance @daz1uk?
Love it! As one of the folks who keeps "known good cables" separately from the rest of the flock.
That's a cool idea, I struggled with this issue a few times before and wondered why my device was charging slower than usual.

Who hunted WhatCable?
WhatCable was hunted by Zac Zuo. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.

Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
