Meta has sold 7M+ Ray-Ban glasses that look identical to normal glasses but can record you silently.
NoPeek detects them using immutable BLE manufacturer company IDs signals that cannot be randomized or hidden unlike MAC addresses.
Detects: Meta Ray-Ban, Snap Spectacles, Oakley Meta, TCL RayNeo, Meta Quest, Apple Vision Pro, Pico VR and more.
No ads. No tracking. No internet permission. Fully open source. MIT license.
How does it differ from Nearby Glasses, apart from detecting more AR headsets?
Good question, seems newer but rely on the same mechanism.
Someone else mentioned the less copyleft license (MIT vs. AGPL) as something to consider.
