A few months ago, a neat little experiment landed in Chrome’s hidden labs: the ability to split a single browser tab into two independent, resizable panes. Back then, it felt like a curiosity for power users who like to live in chrome://flags; now it’s started arriving in the stable channel — which means most people don’t need Canary, Beta, Dev, or fiddly flags to try it. Google promoted Chrome 143 to the stable channel on December 2, 2025 (builds for Windows and macOS appear as 143.0.7499.40/41), and the rollout includes the Split (or Split View) functionality that people have been testing for months.

If you’ve ever been juggling two tabs — a research doc and a draft, product pages you’re comparing, or a support chat next to an admin console — you know the pain: either you open another window and wrestle with the OS window manager, or you alt-tab until your fingers are sore. Split Tabs changes that workflow by letting two pages live together under one tab in a single window, each in its own pane. The panes are resizable, you can swap left and right, open links from one pane into the other, and pull the two panes apart again into separate tabs when you want. Practically speaking, it’s what tab multitasking should have been all along.

Using it is pleasantly low-friction. When Split Tabs has reached your machine, right-clicking a tab shows a “Add tab to new split view” option; pick another open tab and Chrome merges them into one combined tab with two live views. A small menu icon appears near the address bar that lets you quickly swap panes, close one side, or break the split back into two separate tabs — and there’s also a control between the panes at the bottom of the window for the same actions. That little, obvious menu is worth calling out: it makes Split Tabs feel like a deliberate UI decision rather than a half-baked add-on. Detailed first-hand write-ups from testing outlets describe these exact controls and the context-menu wording, and they walk through the experience of dragging the split handle to rebalance space or opening links from one pane into the other.

A quick practical example: say you’re comparing two laptops. Open the first review and the second review in two tabs, right-click and select the split option, and suddenly you have specs and photos side-by-side — no window snapping, no duplicated address bars, and no extra clutter in the taskbar. Or if you write in one tab and preview in another, you can keep your preview visible while you type. For people who work across multiple monitors, the feature compounds well — you can have two windows, each with its own split tabs, effectively giving you a tidy multi-pane setup without creating a dozen windows.

A couple of caveats: Google is doing a gradual rollout, so even though Chrome 143 is in stable, not everyone will see the split option immediately. If it hasn’t shown up in your copy yet, that’s normal; a handful of outlets that tested the feature spotted it pop up on some machines before it was universally available. For people who can’t wait, the experimental flag (chrome://flags/#side-by-side) is still the shortcut to enable Split Tabs manually, but that’s only for adventurous users who are comfortable with experimental features.

There’s also context worth noting about the market: Chrome isn’t inventing split browsing — rival browsers like Edge, Vivaldi and Brave have long offered ways to view pages side-by-side — but Chrome’s approach is intentionally simple and tightly integrated with the tab strip and address bar. That simplicity is its strength: it lowers the friction for anyone who isn’t already deep in a niche browser’s settings. If you’re a heavy multitasker, the feature moves a routine desktop habit (snapping windows) into the browser where it probably belongs.

If you want to check for it right now: update Chrome to the latest stable (About Google Chrome will show your version), then right-click a tab and look for “Add tab to new split view.” If you don’t see it, you can either wait a few days — the stable rollout is staged — or, if you’re comfortable poking experimental settings, type chrome://flags/#side-by-side and flip the flag to Enabled, then relaunch. Bits of the rollout (and even some security fixes tied to the new behavior) shipped as part of Chrome 143, so keeping Chrome up to date is the right move.

For most people, the split tab arrival is a modest but meaningful productivity upgrade: no new software, no plugin, just a cleaner way to do something everyone already does. If you like working with two pages at once and hate window clutter, give it a spin — if it has hit your machine, you can be up and running in seconds. If it hasn’t, the flag route or a short wait will get you there.

Want a short tip before you try it: once you’ve split a tab, hover or glance for that little menu next to the address bar — that’s where you’ll quickly find swap, close, and undock actions. Small UI details like that are what turn a clever experiment into something you actually use every day.
