Twitch, the Amazon-owned livestreaming giant, has officially launched alpha testing for vertical video streams. The initiative, first unveiled during the annual TwitchCon event in Rotterdam earlier this year, aims to modernize the platform’s viewing experience. Recent data from market intelligence provider AppSensa confirms that these tests are now active for a select group of creators.
Challenging the Vertical Video Dominance
By integrating a vertical format, Twitch is positioning itself to compete more aggressively with established short-form video powerhouses such as TikTok, Instagram Reels, and YouTube Shorts. Technical analysis of the latest app build reveals specific references to the feature, outlining a dedicated user interface designed to support this new orientation.
Key Features and User Experience
The current implementation includes a “vertical theater mode” complete with specialized UI elements. To ensure a smooth transition for the community, Twitch has integrated a toggle mechanism that allows viewers to switch between the classic horizontal format and the new vertical view at their convenience.
When users first encounter the update, they will be greeted by educational dialogs confirming that “vertical video is here,” while explicitly noting that the feature is in a testing phase. Furthermore, the app code indicates that the infrastructure includes necessary permission handling for camera and microphone access, essential for mobile-first live broadcasting.
Limited Rollout and Future Expansion
While the testing is currently restricted to a handful of streamers, the scope is expected to grow. A Twitch spokesperson declined to provide specific details on the current participants but reaffirmed the company’s keynote announcement from TwitchCon, which promised a phased rollout throughout the summer. The company intends to expand these tests to a broader user base later this year.
This vertical video push is part of a larger update strategy for the platform. During the same TwitchCon event, the company also announced plans to experiment with dual-format streaming and 2K resolution support for a select number of channels.
