YouTube Live Danmaku

Watch YouTube live streams and chat replays with scrolling danmaku overlaid on the video. Features: • Live and replay chat shown as Canvas danmaku on the player • Fetches chat through YouTube’s own endpoints in your browser session (does not depend on the side chat panel being open) • Adjustable font size, opacity, and scroll speed • Pause freezes on-screen danmaku • Chat stickers and custom emojis appear in danmaku • Consistent color per nickname • Popup UI in English or Traditional Chinese Privacy: • Only the “storage” permission is used, to save your settings locally • No analytics, ads, or data sent to the developer v1.1.0 • Chat is now fetched via YouTube’s InnerTube live chat / replay APIs instead of scraping the chat DOM • Removed “hide official chat” option v1.2.0 • Fixed live danmaku stopping after a while while API requests continued (always advance chat continuation tokens) • Fixed settings sometimes not applying, and popup values resetting after reopen (local storage + debounced saves) • Hint users to close YouTube’s official chat panel for smoother performance v1.3.0 • Pause live/replay chat API polling when the tab is hidden, so returning won’t dump a burst of danmaku • Keep on-screen danmaku moving in the background using real elapsed time (browsers pause requestAnimationFrame on hidden tabs)
