Features

Everything in ViewSync is built for creators who need tight, multi-angle YouTube playback in one tab.

  • Official YouTube playback

    Every tile uses the YouTube IFrame Player API. We never overlay or hide YouTube controls or download video.

  • One URL, many players

    Spawn up to 12 synced players from a single link — ideal for offset comparisons or mirrored layouts.

  • Flexible layouts

    Auto grid, 1+N spotlight, side-by-side, PiP focus, and vertical mode for Shorts-style feeds.

  • Per-video offsets

    Align feeds with second-level start offsets and ±0.1s nudges when sources don’t start together.

  • Master clock sync

    A master timeline corrects drift with seek and gentle rate tuning while respecting buffering states.

  • Mute, solo, and volume

    Mute individual tiles, solo one audio source, or drive master volume across the session.

  • Drag to reorder

    Reorder tiles to match your edit or stage layout before you hit play.

  • No signup for the tool

    Open the app and sync — account features will come with the admin CMS for site content.
