SpaceTab

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. 🆓 OPEN SOURCE MIT licensed.

Opinionated about a single workflow — project spaces with instant switching — and refuses to add accounts, sync, or paywalls.
