TrueLive от Vitor Plentz

YouTube's "live" isn't really live: the player deliberately holds you several seconds behind — and part of that video is already downloaded on your computer. In any live stream (the goal, the drop, the announcement) it's the difference between reacting together and finding out from the chat.

TrueLive keeps you pinned to the newest point available:

• Super Live: the lowest delay the stream and your internet allow, with 4 automatic protection layers — a safety floor measured from your own connection, preemptive reaction to bitrate spikes, an instant rescue instead of freezing (playback speed never drops below 1.0x), and automatic suspension if your connection can't keep up.
• Auto: balance without thinking. It reads your connection and adjusts by itself.
• Real delay badge in the player (optional): see in seconds how far behind live you are — actually measured, not estimated.

How much you gain depends on the stream (the channel picks the latency class): on low-latency streams we measured ~3-4s from broadcast to screen, broadcast-TV territory, versus ~7s on the default player. On normal-latency channels the physical floor is higher (~10s+) and no extension can break it — TrueLive guarantees you the minimum from there. Measured, verified numbers, with public methodology in the repository.

No sign-up, no data collection, no external requests — everything runs locally in your browser. Open source (GPL-3.0).
