Yes. Tabvora is 100% free software distributed under the permissive MIT License. There are no hidden subscriptions, premium paywalls, or feature limits.
Never. Tabvora runs entirely on your local machine. All shortcuts, workspace folders, notes, and settings are saved in standard browser chrome.storage.local/IndexedDB storage and never transmitted over the internet.
Tabvora uses a virtual scrolling grid, so it only renders the shortcuts currently visible on screen. This keeps the new-tab dashboard fast and responsive even with hundreds of saved shortcuts.
