Tabby: Every tab, exactly where it should be

Meet Tabby, AI that knows what to keep, what to close, and what deserves your focus.

A smarter way to browse, with an intelligent workspace manager that transforms messy tabs into structured, project-based workflows. Tabby lets you group, clean, and manage browser tabs within contextual workspaces. Leverage on-device AI to intelligently sort, tag, and organize your tabs and resources.

Features

• Workspaces — Create isolated tab contexts; switch between them seamlessly
• Tab Groups — Automatically group and organize tabs within a workspace
• Resources — Save bookmark-like collections tied to workspaces
• AI Workflows — On-device sorting, grouping, and tab cleanup
• One-Click Sync — All changes persist across browser sessions

Tech Stack

• Extension Framework: WXT
• UI: React + TypeScript + Tailwind CSS + shadcn/ui
• Database: IndexedDB with Dexie.js
• AI: Chrome Built-in APIs
• Package Manager: pnpm

Requirements

• Node.js (LTS recommended) and pnpm
• Chrome or Chromium-based browser

Quickstart

1. Install dependencies

pnpm install

2. Build or run in dev

pnpm build
pnpm dev

3. Load the extension in Chrome

• Open chrome://extensions/
• Enable Developer mode
• Click “Load unpacked”
• Select the output directory inside .output/

You’re in! Tabby will start with an “Undefined” workspace that previews your currently open tabs.

First Run Tips

• Bootstrap from Undefined

  • Open the “Undefined” workspace
  • Click the three-dot menu
  • Create a new workspace “from Undefined” to snapshot your current tabs

• Command Menu

  • Press Control + Space (Windows/Linux/macOS) to open the command menu
  • Ask Tabby to clean up, group, tag, or rename tabs

• Configure Tabby Engine

  • Go to Settings → Preferences → Tabby Engine
  • Engine options:
    • Cloud: Best for very large workspaces and many windows
    • Local: Fast, private, and ideal for light cleanup, renaming, and small/medium groups

• Troubleshooting:

  • If cloud dev endpoints error in your environment, switch to Local
  • Or create your own Firebase project and point Tabby to it for full control

Recommendations

• Use Cloud when:
  • You have hundreds of tabs, multiple windows, or large workspaces
• Use Local when:
  • You want maximum privacy, minimal latency, or are doing light grouping/cleanup
