Tabwise: Vertical Tabs & Workspaces

About

If your browser looks like this right now:
• 47 tabs open
• 6 GitHub tabs
• 3 Figma files
• 4 Gmail instances (why??)

…Tabwise is for you.

Tabwise brings Arc Browser’s vertical tab experience to Chrome, Brave, Edge, and AI browsers like Comet, Atlas, and Dia: a clean side panel with Favorites, Workspaces, Smart Tab Switching, and true Immersive Browsing.

Not affiliated with Arc Browser or The Browser Company. This is an independent extension inspired by a workflow many people love.

😫 The problem

Horizontal tabs don’t scale. After 10–15 tabs:
• You can’t read tab titles (favicon roulette begins)
• You open duplicates by accident
• Context switching between work/personal/projects becomes chaos
• Browser chrome is always visible—no escape from the clutter

Bookmarks don’t help either—they always open a new tab instead of focusing the existing one.

✅ The solution: Tabwise

A vertical tab manager that behaves like a workspace—with the option to disappear completely when you need to focus.

🚀 Key features
⚡ Smart Tab Switching (no more duplicates)

Click Gmail → Tabwise focuses your existing Gmail tab.
Click again → stays on that tab. Not a new one.
No more “Gmail tab #5” situation.

Shift+Click = force open a new tab when you actually want a second instance.

⭐ Favorites Grid (Arc-style)

Your most-used sites in a clean 4-column favicon grid.
• One-click access to daily tools
• Visual indicators when a site is already open
• Drag to reorder

🗂️ Workspaces (collapsible context groups)

Create workspaces like:
• Work → Slack, dashboard, docs, email
• Client A → portal, reports, tickets
• Personal → social, finance, shopping

Collapse what you’re not using. Switch contexts with one click.

🔍 Quick Search (keyboard-first)

Press Cmd/Ctrl + K to search across:
• Favorites
• Workspace items
• Open tabs
Press Enter to jump instantly. Never hunt for tabs again.

🌐 Immersive Browsing Mode

Toggle the sidebar with Cmd/Ctrl + Shift + E.
Hide Chrome’s tab bar.
Result: ZERO browser chrome visible.

True full-screen, app-like web experience. Tabs appear only when you summon them. No browser offers this out of the box.

📂 One-click Tab Grouping

Overwhelmed with 7 GitHub tabs and 5 Figma tabs?
One click groups all tabs by domain. Collapse groups. Close all at once.

Smart handling for Google Docs, Sheets, and Slides—each gets its own group.

🎯 Who is Tabwise for?

• Arc Browser refugees → vertical tabs + workspaces in Chrome/Edge/Brave
• Power users (20+ tabs) → horizontal tabs become unreadable; vertical tabs show more
• Developers & PMs → GitHub, localhost, Jira, docs in separate project workspaces
• Knowledge workers → researchers/designers/writers juggling multiple contexts
• AI browser users → Comet/Atlas/Dia + the vertical tab management they’re missing
• Focus-mode seekers → distraction-free browsing with tabs on-demand (Immersive mode)

If you usually browse with <5 tabs, you probably don’t need this.

⌨️ Keyboard shortcuts

Cmd/Ctrl + Shift + E → Toggle sidebar (Immersive mode)
