Download FAQ

Is TabMaster really free?

Yes! The Free tier includes tab viewing, close, activate, one group, one pin, recently closed recovery, focus filter, keyboard navigation, and multi-browser support. Pro unlocks search, tab thumbnails, stashing, action tabs, bulk operations, unlimited groups & pins, custom shortcuts, and more.

Is it safe to download?

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. Your sign-in token is stored safely in macOS Keychain — Apple's encrypted, OS-level vault. We don't store passwords or browsing data in the Keychain. All IPC payloads are validated. No browsing data is collected.

What will Gatekeeper show on first launch?

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.

Why does macOS ask about Keychain access?

TabMaster uses macOS Keychain to securely store a small session token that keeps you signed in and syncs your Pro status. Keychain is Apple's built-in encrypted vault — the same one Safari and Mail use. We never store passwords or browsing data there. If macOS shows a prompt, it's simply confirming that TabMaster can access the token it created. This is standard macOS security.

Do I need the browser extension?

Yes. TabMaster's companion extension, TabMaster Bridge, is what keeps your open tabs in sync with the app. Install it once in each Chromium browser you use (Chrome, Edge, Brave, and others). It's free, lightweight, and only communicates with the app on your own Mac over a loopback-only local connection — no browsing data is sent anywhere.

Will it slow down my Mac?

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.
