Twitch Enters Vertical Video Territory with Alpha Test
App string analysis uncovers Twitch's experimental vertical video streaming feature targeting select creators.
Twitch is letting select streamers go vertical
Feature Analysis
Our research identified:
- Limited alpha testing with "a few streamers" according to in-app strings
- Vertical theatre mode with dedicated user interface elements
- Mobile-optimized viewing with toggle between classic and vertical views
The discovered strings reveal Twitch is positioning this as an experimental feature with "limited functionality" during the alpha phase, suggesting cautious rollout to gauge creator and viewer adoption.
Technical Implementation
String analysis shows:
- Seamless view switching between traditional and vertical formats
- First-time user education through modal dialogs explaining the feature
- Enhanced collaboration features with improved audio/video controls for mobile creators
Key String Changes
