splitescreen — Split Screen Workspace

🪟 splitescreen — split your screen into side-by-side windows, the reliable way. Tired of switching between tabs? splitescreen arranges your browser into a side-by-side split screen layout using REAL browser windows — so every website works (Gmail, Google Docs, YouTube, banking all tile fine), and every one of your extensions keeps working on every pane. No iframes, no broken pages, no "this site can't be displayed". ⚡ ONE-CLICK SPLIT • Open the popup and click a layout — it tiles your active tab plus the tabs to its right into side-by-side windows. • Each layout thumbnail previews which page lands in each pane (with its favicon), so you see the result before you click. 🧩 LAYOUTS FOR EVERY WORKFLOW • Built-in layouts: Left/Right, Top/Bottom, 2×2 grid, 3 columns, a thin Main + Sidebar (70/30), and an ultrawide Focus split (25·50·25). • Build and save your own: any split ratio with a slider, an asymmetric 3-pane (e.g. 25·50·25), or a custom grid. • Left / Right align to flip which side your current page takes. • Smart sizing: a ratio that would shrink a window below your screen's usable minimum is adjusted automatically, so split panes never overlap. 🖥️ MULTI-MONITOR • Auto-detects the screen you're working on, and lets you send a split to any monitor from a clickable monitor map — perfect for dual-monitor and ultrawide setups. ↩️ UNDO • One click restores your windows to exactly how they were before the split — size, position, even maximized state. 💾 WORKSPACES • Save your current split — its sites AND their exact tiled arrangement — and reopen the whole thing in one click. Synced across your devices. 🔒 PRIVATE BY DESIGN • No tracking. No analytics. No ads. Nothing ever leaves your browser. • Minimal permissions — and the extension never reads or changes the content of your pages. Works on Chrome and other Chromium-based browsers (Microsoft Edge, Brave, Opera). ❓ FAQ Q: Can it split two pages inside a single tab? A: It tiles real, separate browser windows side by side — not an iframe inside one tab. That's on purpose: it's why every site loads (including Gmail, Docs and banking sites that block iframes), and why your other extensions keep working on each pane. Q: Does it work on every website? A: Yes. Because each pane is a normal browser window, pages load exactly as they always do — no embedding errors. Q: Does it support multiple monitors? A: Yes — it detects your current screen, and you can send a split to a specific monitor. Q: Does it collect my data? A: No. There's no tracking, no analytics, and no external server. Your settings, layouts and workspaces stay in your browser (and sync through your own Google account if you're signed in). Q: Which browsers are supported? A: Chrome and other Chromium-based browsers such as Microsoft Edge, Brave and Opera.
