Dualless Review — Split Your Browser Window Into Two Panels Side by Side
Dualless splits your Chrome window into two panels — left and right — at ratios you choose (50/50, 60/40, 70/30, and others). Each panel is an independent Chrome window showing a different tab. For creators who regularly reference one document while working in another — writing in Docs while reading research, editing in one tool while checking a reference in another — Dualless simulates a dual-monitor setup in a single screen.
Install on Chrome Web Store →Key Features
One click splits the current Chrome window into two side-by-side windows at your chosen ratio. Both windows function independently — you can scroll, type, and navigate in each without affecting the other.
Multiple ratio options (40/60, 50/50, 60/40, 70/30) let you allocate more screen space to the window that needs it — a wider writing panel and narrower reference panel, for example.
The split can be undone by closing one of the created windows. Dualless doesn't modify Chrome's internal window management — it simply opens and positions two windows at the specified dimensions.
Dualless works on any screen size, though the benefit is most significant on larger displays where two panels each have enough width to be comfortably usable.
Who Is It For
Creators who work on a single monitor and regularly need to reference content in one browser location while working in another. Script writers referencing research, editors checking shot lists against a schedule, or newsletter writers cross-referencing multiple sources simultaneously will find the split view useful.
Creators who already have multiple monitors will get minimal benefit — a second physical monitor handles the split-screen use case better than a browser extension. Also less useful on smaller laptop screens where the split width becomes too narrow to be practical.
Pros and Cons
- ✅ Instant split-screen without external software
- ✅ Multiple ratio options for different content balance needs
- ✅ Completely free
- ❌ Each panel is a separate Chrome window — bookmarks and tab groups are not shared
- ❌ Less useful on smaller screens where panel widths become impractical
Pricing
Dualless is completely free. No paid version, no account required.
Summary
Worth installing for single-monitor creators who frequently work with two browser-based resources simultaneously. The split-screen benefit is immediate for writing alongside research or checking references during editing work. On dual-monitor setups, the extension adds no value.
