The native macOS menu-bar tab manager. Search, group, stash, preview, and switch tabs across Chrome, Edge, Brave & other Chromium browsers with one global shortcut and 40+ keyboard shortcuts.
Companion extension — required
Install it once in each Chromium browser you use — Chrome, Edge, Brave and others.
Setup guide →TabMaster is free to try for 7 days, with every feature unlocked and no card or account required. After that it's a one-time purchase — a lifetime license for $9.99, not a subscription. When the trial ends, tab actions lock until you activate a license; nothing you set up is lost.
Absolutely. TabMaster is code signed and notarized by Apple, so macOS Gatekeeper can verify it hasn't been tampered with. The renderer uses context isolation with no Node access. The companion extension talks to the app over a loopback-only local connection that never touches the network. There are no accounts and no passwords to store. All IPC payloads are validated. No browsing data is collected.
Gatekeeper may show a standard macOS prompt the first time you open TabMaster. This is normal for signed and notarized apps and is macOS confirming the app is verified by Apple. You do not need to bypass Gatekeeper or run any special commands.
Your license key is shown on the confirmation page right after checkout and emailed to you as well. In TabMaster, click the ☰ menu beside the search box → License, paste your key, and activate. A license is active on one Mac at a time, and you can deactivate it from that same screen to move it to another Mac.
Yes. TabMaster's companion extension, TabMaster Bridge, is what keeps your open tabs in sync with the app — without it the app has no tabs to show. You'll find it on the Chrome Web Store: install it once in each Chromium browser you use (Chrome, Edge, Brave, and others). It's lightweight and only communicates with the app on your own Mac over a loopback-only local connection — no browsing data is sent anywhere. See the extension setup guide for per-browser steps, including Edge and incognito.
No. TabMaster disables Chromium background throttling, uses a powerSaveBlocker, and pre-loads the renderer at startup for instant popover activation. It runs outside the browser sandbox with minimal resource usage, and the companion extension does little more than relay tab updates.
