Verify First — Meta Quest Development
What you need to know before reading the rest of this
You are about to be told to call tools you may not recognize by name. Read this section first so the rest makes sense.
- Meta Quest is Meta's line of standalone VR / mixed-reality headsets (Quest 2, Quest 3, Quest 3S, Quest Pro). They run an Android-based OS.
- Horizon OS is the name of that operating system. It is forked from Android, ships on every Quest headset, and Meta updates it on its own cadence (separate from upstream Android). Many APIs are Horizon-OS-specific and have no analog in stock Android.
- hzdb ("Horizon Debug Bridge") is a Rust CLI tool published by Meta as
@meta-quest/hzdbon npm. Invoke vianpx -y @meta-quest/hzdb <args>— no install required;npxalways pulls the latest published version. It wrapsadband Meta's developer APIs into higher-level commands for Quest device development: list devices, install apps, capture Perfetto traces, search Meta Quest documentation, query 3D asset libraries, automate UI
