About Slate - Window per Project
Tired of mixing 50 tabs from 5 projects in one Chrome window?
Slate gives each project its own Chrome window. It saves your tabs, tab groups, and pinned tabs - and restores everything exactly when you switch back.
━━━ FEATURES ━━━
✦ One Chrome window per project
Closing the window saves the tab set. Reopening the project restores it - same tabs, same groups, same pinned state, same active tab.
✦ Tab groups preserved
Group titles, colors, and collapsed state survive the round trip.
✦ Pinned tabs preserved
Pinned state restored on reopen.
✦ Active tab restored
The tab that was active when you last closed the window is reactivated.
✦ Toolbar badge per window
Each project's initials show on the toolbar in its color, so you always know which project window you're in.
✦ Side panel manager
Rename, reorder (drag & drop), change icons and colors, delete projects - all in Chrome's built-in side panel.
✦ Icon picker
Choose from 335 curated Lucide icons, or upload your own image (PNG, JPG, SVG, WebP up to 512 KB).
✦ Import / export
Move your projects between machines as a JSON file.
✦ Optional CLI
A small bash wrapper lets you control Slate from the terminal:
slate open "Work"
slate close "Work"
slate list
━━━ WHY SLATE ━━━
Most tab managers store sessions you have to manually restore. Slate ties projects to Chrome windows, auto-saves on every change, and treats your work as named workspaces - not just bookmarks.
If you've tried One Tab, Session Buddy, or Workona and felt they were either too heavy (whole separate UI) or too light (just a list of saved sessions), Slate is the middle ground: each project lives in its own real Chrome window, the way Chrome was meant to be used.
━━━ PERMISSIONS ━━━
Slate requests only what it needs:
- tabs, tabGroups - read URLs, titles, pinned state, and group metadata so they can be saved and restored
- storage - save projects locally on your device via chrome.storage.local
- sidePanel - show the project manager in Chrome's side panel
No host permissions. No content scripts. No network access.
━━━ PRIVACY ━━━
100% local. No accounts. No servers. No telemetry. No analytics.
Slate makes zero outbound network requests. Your projects, tabs, and icons live in chrome.storage.local on your device. They are never uploaded, sold, or shared.
