  description

  StreamStack is a Chrome extension that allows users to watch multiple live streams simultaneously in a single organized view. It detects HLS video streams (.m3u8) playing in open browser tabs and displays them together in a customizable grid layout.
  Core features:
  
  Automatically detects HLS streams across open tabs using the webRequest API
  Displays multiple streams in 2×1, 2×2, or spotlight layouts
  Supports stream swapping, fullscreen, and per-stream controls
  One-time license purchase ($9.99) unlocked via a license key entered in the popup
  
  Permissions used:
  tabs — to enumerate open tabs and find active video streams
  webRequest — to monitor network requests and detect .m3u8 stream URLs
  storage — to persist the user's license key across sessions
  host_permissions — required for webRequest to observe requests across sites
  
  The extension does not collect, transmit, or store any user data. License validation is performed entirely client-side using the Web Crypto API. No external servers are contacted by the extension itself. Extension does not provide any streams, only identifies valid stream formats in open tabs.

  StreamStack — Watch Multiple Streams at Once
  StreamStack automatically detects live video streams playing in your browser tabs and lets you watch them all at the same time in a clean, organized grid.
  Perfect for sports fans who want to follow multiple games, matches, or races simultaneously without switching tabs. Also works with gaming streams and identifies most streams. 
  
  How it works
  Open your streams in separate tabs as you normally would. Click the StreamStack icon and it instantly finds all your active streams. Choose your layout and hit Open Multi-View — all your streams appear together in one view.
  Layouts
  
  2×1 — Two streams side by side
  2×2 — Four streams in a grid
  Spotlight — One main stream with others in a sidebar. Click any sidebar stream to bring it to focus.
  
  Features
  
  Automatically detects HLS streams on any website
  Click any sidebar stream to swap it to the main view
  Remove or refresh individual streams without reloading
  Streams stay muted in the sidebar and unmute when brought to the main view
  
  One-time purchase of $9.99 — no subscription, no recurring fees. Your license works forever.
