SpaceTab

About

SpaceTab turns your sea of open tabs into named project spaces — Engineering, Reading, Shopping, anything — and switches between them in milliseconds.

✨ INSTANT SWITCHING
Inactive spaces sit in a hidden Chrome window, fully loaded. Switching swaps tabs between this vault and your visible window — no re-fetching, no waiting, no losing scroll position.

🧠 SMART ARCHIVE
One click clusters your current window's tabs by domain into suggested spaces. Review, rename, confirm.

🎨 CHROME TAB GROUPS PRESERVED
Group color and title round-trip through archive and switch. Your visual organisation survives.

⌨️ COMMAND PALETTE (⌘K)
Switch spaces, toggle theme, archive, import/export — every action one keystroke away.

✅ POWER FEATURES
• Multi-select tabs (⌘/Ctrl+click, Shift+click for ranges) — bulk open, move, delete
• Discard inactive tabs to free RAM (single tab or all at once)
• Pin spaces; emoji + note per space; manual reorder by drag
• Drop tabs across spaces, drop spaces onto each other to merge
• Cross-space search + per-space search
• 8-second "undo" after every space switch
• Light, dark, and system themes
• 5 languages: English, 简体中文, 繁體中文, 日本語, Deutsch
• JSON export/import — your data is portable

🔒 PRIVACY-FIRST
SpaceTab does not collect, transmit, or sell anything. No telemetry, no analytics, no servers. Your spaces live in chrome.storage.local on this device.

WHY ANOTHER TAB MANAGER
SpaceTab sits between OneTab (lightweight collector) and Workona (heavyweight workspace SaaS). Opinionated about a single workflow — project spaces with instant switching — and refuses to add accounts, sync, or paywalls.
