Three steps, no account:

1. Open the Workspace.
2. Type a URL in the global bar and press “Apply to all”, or set each pane's URL on its own.
3. Press “Load all”. Add panes up to 12, pick a layout, and go.

Eight layouts: Single, Two Columns, Three Columns, Grid 2 × 2, Top One Bottom Two, Left One Right Two, Grid 3 × 2, and Grid 3 × 3. The layout only arranges panes — it never changes what is loaded in them.

With Sync on, changing the URL in any pane — or in the global bar — updates every pane to the same URL. It is useful for comparing the same page across sites, or for loading one link everywhere at once. With Sync off, every pane is independent.

AI Arena takes you to Ask Everywhere. ChatGPT, Gemini and Claude refuse to load inside a pane, so instead of three blank boxes you type one prompt and each AI opens in its own browser window, tiled across your screen.

YouTube Multi-View takes you to Stream Multi-View, where you paste YouTube or Twitch links and the official players play side by side in the page. You can add the same stream more than once if you need multiple players.

Research Mode opens Wikipedia and an example page that both allow framing, plus a Notes pane to write in. Any site that blocks framing shows a card with “Open in window” and “New tab” buttons instead of a blank pane.

Name a set of panes and save it. Saved workspaces live in your browser's local storage — they are never uploaded, and they do not follow you to another device or browser. Load one from the list, or delete it when you are done.

Share a workspace

Press “Copy share link” in the workspace toolbar and send the link to anyone. When they open it they get the same panes in the same layout. The workspace is stored inside the link itself (/workspace?pane=…&pane=…&layout=grid-2x2) — nothing is uploaded and there is no account. The link is built when you press the button, so your browser history is not filled with every change. Up to 12 panes are included; if a link grows past about 2,000 characters you will be told, because some apps truncate long links.

Notes pane

“Add notes” adds a notepad pane next to your sites. What you type is saved in this browser as you go, and it is stored with the workspace when you save it. A note is added to a share link only if the whole link stays under about 2,000 characters; otherwise the note is left out and you are told so.

Do I need to install anything?

No. MultiPane runs in your browser. Open the Workspace page and start adding panes.

Why is a pane blank?

Some sites restrict embedding, so a pane may not display its content. This is the site's security policy, not a bug in MultiPane. Use the pane controls to open it in a window or a new tab.

Is my browsing sent to a server?

No. Panes load directly from your browser to the site. Saved workspaces are stored in your browser's local storage only.

Can I use MultiPane to increase YouTube views?

No — and you should not try. Repeated playback does not reliably generate additional valid views, and fake engagement can lead to strikes or channel termination.

How many panes can I open?

Up to 12. In practice, 3–6 panes stay readable on a laptop screen.
