TabVault

TabVault is an open-source, zero-data-loss browser tab manager designed from the ground up for Chrome Manifest V3 and Firefox.

Unlike legacy tab extensions that store tabs unsafely in browser caches and risk sudden data loss during crashes or updates, TabVault guarantees data safety with atomic storage staging and automated Google Drive cloud backups.

Key Features:

• Reclaim up to 95% of browser RAM with one-click window collapse.
• Zero Data Loss Guarantee: Strict schema validation, atomic writes, and crash recovery staging.
• Automated Google Drive Cloud Sync: Back up your sessions directly into your personal Google Drive with zero server costs or third-party custody.
• 100% Private: Zero telemetry, zero tracking, and no external developer servers. All data stays local.
• 1-Click OneTab Importer: Paste your existing OneTab exports and import all your groups in seconds.
• 1-Click Notion, Markdown, CSV & Netscape Bookmarks Export.
• Tab Threshold Alerts: Real-time warnings when open tabs exceed your custom memory ceiling.
• Custom Session Tags: Organize workspaces and filter sessions by tag.
