Take Control of Every Browser Tab

TabMaster supports Google Chrome, Microsoft Edge, Brave, and other Chromium-based browsers. A lightweight companion extension — TabMaster Bridge — runs in each browser and streams tab data (title, URL, window, active state, pinned/incognito flags) to the app over a loopback-only local connection. Install it once per browser and TabMaster manages them all from one place. In Edge you'll need to allow extensions from other stores the first time, since the extension is distributed through the Chrome Web Store.

No. TabMaster is a privacy-first tab manager. All data stays on your Mac — pinned tabs, groups, stashed tabs, action notes, and recently closed tabs are stored locally. There are no accounts and no sign-in: the only time TabMaster contacts a server is to start your free trial or verify your license key, and it sends a one-way hashed identifier for your Mac rather than anything about your browsing. No cloud sync, no ads, no trackers.

Yes. TabMaster is code signed and notarized by Apple, which allows macOS Gatekeeper to verify the app is trusted and unchanged. On first launch, Gatekeeper may show a standard prompt — that's normal and confirms the app is verified. You never need to bypass Gatekeeper or run unsafe commands.

Yes. TabMaster pairs a native macOS app with a small companion extension called TabMaster Bridge, available on the Chrome Web Store. Install it once in each Chromium browser you use (Chrome, Edge, Brave, and others) and it keeps your open tabs in sync with the app. The extension only talks to the app on your own Mac over a loopback-only local connection — no browsing data is sent to any server. If no browser with the extension is connected, TabMaster tells you so and reconnects automatically once one is.

Press Cmd+G (rebindable in the app) to toggle TabMaster from anywhere — it works system-wide across every macOS Space. You can also click the menu bar icon. The palette auto-focuses the search box so you can start typing instantly.

No. TabMaster disables Chromium background throttling and uses a powerSaveBlocker to stay responsive even when hidden. The renderer is pre-loaded at startup (warm loading), and Redux selectors are memoized for efficient re-renders.

The companion extension captures a lightweight JPEG thumbnail of each browser window's active tab and sends it to the app, so you can glance at a tab before switching to it. No macOS Screen Recording permission is required — the thumbnails come from the browser itself. Background tabs show a placeholder until you visit them. Like everything else, the thumbnails stay local to your Mac.

Stashing auto-closes inactive tabs on a configurable cycle (5–120 minutes, default 30). Pinned, active, protected (shield icon), whitelisted, action-tagged, and optionally grouped/incognito tabs are skipped. Stashed tabs (up to 100) are preserved locally and can be restored with one click.

Yes. The palette opens centered on whichever display your cursor is on, in the macOS Space you're already in — including full-screen Spaces — so summoning it never drags you to another desktop. Search, filter, and jump across all windows and monitors instantly. Stable window ordering (W1, W2, W3…) keeps the view consistent.

Only if you let it. Chromium hides incognito tabs from extensions by default, so TabMaster's incognito filter stays empty until you open your browser's extensions page, find TabMaster Bridge, and turn on "Allow in Incognito" ("Allow in InPrivate" in Edge) — per browser. Even then, incognito tabs stay out of the recently-closed list so their URLs are never written to disk, and auto-stashing skips them unless you explicitly opt in. The incognito filter only appears when there are incognito tabs to show.

A tab manager that lives inside one browser can only ever see that browser's tabs. TabMaster is a native macOS app that manages tabs across Chrome, Edge, Brave, and other Chromium browsers at once. Its companion extension is deliberately tiny — it just syncs tabs — while the app delivers 40+ keyboard shortcuts, bulk multi-select operations, color-coded groups with auto-add URL rules, action tabs with notes, auto-stashing, tab thumbnails, a system-wide global shortcut, and context-isolated security.

Over 40, and every one of them is a Cmd chord — the search box keeps focus the whole time TabMaster is open, so a bare letter is text, not a command. Arrows navigate, Enter activates, Cmd+W closes, Cmd+T opens a new tab, Cmd+P pins, Cmd+Shift+A selects every visible tab, Cmd+Click and Shift+Click multi-select, Cmd+L switches grid and row layout, Cmd+Y toggles thumbnails, Cmd+Shift+S turns auto-stashing on or off, Cmd+1–9 jumps to a group, Cmd+Shift+1–9 jumps to a window, and Cmd+E / Cmd+Shift+P / Cmd+R / Cmd+S / Cmd+I / Cmd+N switch filters. Press Cmd+/ inside TabMaster for the full reference.

TabMaster is a one-time purchase — a lifetime license for $9.99, not a subscription. Pay once and it's yours, including every future update. There is no monthly or yearly plan and nothing to cancel.

TabMaster is free to try for 7 days with every feature unlocked and no card required — you don't even make an account. When the trial ends, tab actions like switching, closing, and moving lock until you activate a license; your tabs, groups, and settings are all still there and come straight back when you do. The trial is offered once per Mac.

After you buy, your license key is shown on the confirmation page and emailed to you. In TabMaster, click the ☰ menu beside the search box → License, paste the key, and activate. A license is active on one Mac at a time — deactivate it from the same License screen to free it up, then activate it on your new Mac. Your key stays the same.

Only occasionally. TabMaster verifies your license when you activate it and re-checks periodically in the background. In between it works entirely offline, and it keeps working through a generous offline grace period — so a flight or a dead Wi-Fi network won't lock you out.
