Syncroll: Split View Sync Scroller

Sync scroll across Chrome Split View, side-by-side windows, and canvas apps like Figma. Works on any two tabs in any window.

Syncroll keeps two browser tabs scrolling in sync — whether they're in Chrome's native Split View, in two side-by-side windows, or on opposite ends of different Chrome windows. Works smoothly even on canvas apps that other sync extensions can't handle. THREE MODES, ONE EXTENSION • Chrome Split View — Syncroll is the only scroll-sync extension that supports Chrome's native Split View. Open two tabs in Split View, click sync, done. • Side-by-side windows — pick two tabs, tick "Open in new window", and Syncroll launches them as half-width windows on your screen. • Any two tabs, any window — pick the left and right tab from a dropdown. Works across multiple Chrome windows without rearranging anything. WORKS WITH CANVAS APPS Most scroll-sync extensions fail on Figma, Miro, or Excalidraw because those apps render via WebGL and have no DOM scrolling. Syncroll intercepts and relays raw wheel events, so pan/zoom syncs smoothly across canvas pages — just like butter. SUPPORTED PAGE TYPES • Standard websites — syncs by scroll percentage, so pages of different lengths stay aligned • Chat UIs (ChatGPT, Gemini, Slack) — detects the inner scrollable container automatically; sidebar stays put • Canvas apps (Figma, Miro, Excalidraw) — wheel events relayed across panes for true side-by-side panning Any combination works: a Wikipedia article next to a Figma canvas, two ChatGPT conversations side by side, a Slack thread mirrored against a Notion doc. HOW IT WORKS 1. Click the Syncroll icon in your toolbar 2. Pick the left and right tab from the dropdowns (or let Split View detection pre-fill them for you) 3. Optionally tick "Open in new window" to launch the two tabs as half-width windows 4. Click Sync — scroll either side, and the other follows WHAT'S NEW IN 1.1.0 • Pick any two open tabs from a dropdown — no need to set up Split View first • Cross-window sync — sync a tab in one Chrome window with a tab in another • "Open in new window (side-by-side)" mode auto-arranges your two tabs as half-width windows • Full keyboard navigation in the picker (Arrow keys, Home, End, Enter, Esc) PRIVACY No data collection, no tracking, no servers. All scroll synchronization happens locally between your tabs through Chrome's built-in messaging. No external network requests are made.
