A Chrome extension that turns your new tab into a calm, searchable workspace for everything you are browsing.

English · 简体中文

See the whole browser, not just the current tab

TabSlate replaces the default new-tab page with one place to keep browsing context intact. Review what is open, collect pages worth returning to, and resume saved tab groups when a project comes back around.

It is an open-source alternative to Toby and Workona.

Built around browsing context

Organize the work behind your tabs

• Create workspaces and collections for different projects, areas of research, or parts of your day.
• Save pages as visual bookmarks with favicons and metadata instead of letting useful links disappear into the tab bar.
• Keep Chrome tab groups as reusable saved groups, ready to restore in one action.

Find the right thing without losing your place

• Search open tabs, bookmarks, and enabled search engines from the new tab.
• Open the global search overlay with Ctrl+Shift+K on Windows and Linux, or Command+Shift+K on macOS.
• Sort, filter, and work in grid or list views when a collection grows.

Recover, continue, and stay in control

• Catch duplicate tabs before opening another copy.
• Archive or move accidental deletions to Trash, then restore them when needed.
• Sync through a self-hosted TabSlate server or the official cloud service when you want your workspace on more than one device.

Install TabSlate

Chrome Web Store

Install TabSlate from the Chrome Web Store, then open a new tab to start organizing.

From source

git clone https://github.com/TabSlate-dev/TabSlate.git
cd TabSlate
bun install
bun run build

Then open chrome://extensions, enable Developer mode, choose Load unpacked, and select .output/chrome-mv3.

Develop

TabSlate is a React and TypeScript Chrome MV3 extension built with WXT, Zustand, Tailwind CSS, and shadcn/ui. Install Bun first, then use the commands that fit the task:

# Develop with hot reload
bun run dev

# Type-check without creating build output
bun run compile

# Build the production extension
bun run build

# Package a Chrome Web Store upload
bun run zip

The extension has separate new-tab, popup, background-service-worker, and content-script entry points. See ARCHITECTURE.md for the data model, message flows, and codebase map.
