# wuibi: recovering Quibi’s mobile API for a web client

> wuibi reconstructs enough of Quibi’s mobile API to provide search and playback in a browser WebExtension. The author captured iOS and Android traffic, decompiled the Android APK, and recovered readable .proto definitions from embedded Protocol Buffer descriptors. The client then used those definitions to request playback information and hand streaming to Shaka Player; the service’s shutdown has left the client inoperative.
