Overview

GTab is a high-performance, customizable new tab Chrome extension built under Manifest V3 specifications. It consolidates daily task lists, calendar agendas, weather telemetry, and quick notes into a responsive grid layout.

Key Capabilities

  • Zero-Server Architecture: All user data, tokens, and widget states reside entirely within local Chrome storage.
  • Google Services Sync: Direct OAuth2 integration with Google Tasks and Google Calendar APIs without third-party middleman servers.
  • Offline First: Instant tab rendering with cached local state, synchronizing changes seamlessly upon reconnect.
