Unless there's an open version, that's not going to happen. They work by using networks of devices that participate in crowd scanning devices, then tracking devices on a proprietary hosted backend, which is the real product. .if somebody wants to build said backend that tracks millions or billions of these tags out in the world somehow, you'd need to first get all user of mobile phones of a particular OS or manufacturer to participate in scanning and providing you that data, which just won't happen.

A reverse engineered sort of solution is Haystack, but it still uses Apples backend and devices.

Bluetooth beacons are what you call these. There's a few different app-based solutions, all of them proprietary as far as I'm aware, that connect to their brand of beacon regardless of its owner in order to update its position on the map. I feel like this should be possible to do in some way in an open manner, but I'd also be concerned about the security implications behind something like this. I wouldn't want everyone to see where all of my most irreplaceable items are, after all.
