Tabby 🐱

Save, organize, and restore your browser tab groups — with style.

Tabby is a lightweight Chrome extension that lets you snapshot your open tabs into named groups, restore them anytime in a regular or incognito window, and carry your sessions across devices via JSON export/import.

---

Features

• Save tabs — Capture all tabs in the current window as a named group in one click.
• Open in new window — Restore any saved group in a fresh browser window.
• Open in incognito — Launch a group privately in an incognito window.
• Rename groups — Give sessions meaningful names so you can find them later.
• Delete groups — Remove groups you no longer need.
• Export / Import — Back up all your groups to a .json file and restore them on any machine.
• Theme switcher — Toggle between System, Light, and Dark themes.
• Persistent storage — All data is stored locally via chrome.storage.local and survives browser restarts.
