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.
