Feature Comparison

Deep Dive: Unique TabMaster Features

Tab Stashing

Unlike Tab Wrangler's simple auto-close, TabMaster's stash system:

• Runs on configurable 5–120 minute cycles
• Protects pinned, active, shield-protected, whitelisted, and action-tagged tabs
• Optionally skips grouped and incognito tabs
• Preserves up to 100 stashed tabs for one-click restore
• Shows a countdown timer to the next cycle

Live Tab Previews

No extension offers this. TabMaster captures screenshots via three methods:

• **Chrome DevTools Protocol (CDP)** — pixel-perfect captures when Chrome has `--remote-debugging-port=9222`
• **macOS Screen Capture API** — smart window-matching using title, hostname, and browser hints
• **Hidden BrowserWindow fallback** — loads URL in a sandboxed window

All with a 20-second TTL cache and a background scanner that silently visits up to 15 uncached tabs.

Bulk Operations

Extensions process tabs one at a time. TabMaster supports:

• Cmd+Click individual select, Shift+Click range select, Cmd+A select all
• Context menu: Group, Ungroup, Move to window, Move to new window, Close N tabs
• Tabs processed in reverse index order to prevent shifting issues

Action Tabs with Notes

Unique to TabMaster. Tag any tab for follow-up with a text note. Persistent by URL — survives close/reopen. Dedicated filter shows all action tabs.

Performance

Extension Performance

Browser extensions run inside the browser sandbox:

• They share resources with your browser
• Performance degrades with more tabs
• Affected by browser memory pressure
• Can be disabled or broken by browser updates

TabMaster Performance

TabMaster runs as a native macOS Electron app with aggressive optimizations:

• **Background throttling disabled** — Chromium switches keep it responsive even when hidden
• **powerSaveBlocker** — prevents macOS from suspending the app
• **Warm renderer** — pre-loaded at startup so the popover opens instantly
• **Debounced fetching** — 1.5-second debounce after close operations
• **Memoized selectors** — Redux createSelector for efficient re-renders
• Works even when all browsers are minimized

Pricing

TabMaster Free includes: tab viewing/closing across 4 browsers, Cmd+E shortcut, keyboard navigation, one group, one pin, recently closed recovery, focus filter, and three themes.

TabMaster Pro unlocks: search, live previews, auto-stashing, action tabs, bulk operations, unlimited groups with auto-add rules, saved tabs, custom shortcut, domain/browser filters, sorting, move tabs, unlimited pins, accent colors.

Final Verdict

Choose TabMaster if:

• You use multiple browsers (Chrome + Safari + Edge + Brave)
• You want auto-stashing to clean up tabs automatically
• You need live previews before switching tabs
• You use bulk operations to manage many tabs at once
• Privacy matters — context-isolated, local-only, sign-in token in macOS Keychain (no passwords or browsing data stored there)
• You want 40+ keyboard shortcuts for everything
• You need action tabs with notes for follow-up tracking

Choose Extensions if:

• You only use Chrome and want a free, minimal solution
• You just need a simple "send all tabs to a list" feature
• You don't need cross-browser management

Try TabMaster free and see the difference a native, system-tray tab manager makes.
