WebStack is an open-source visual bookmark manager and website stack built with modern Android engineering, Jetpack Compose, and Material Design 3. Rather than juggling endless open browser tabs or struggling to remember URLs, WebStack provides Android users with a unified visual bookmarking experience. Key Capabilities: * Visual Website Cards: Displays responsive page snapshots (via opt-in Microlink service) or clean local aesthetic cards. * Dual Layout System: Effortlessly toggle between rich visual cards and dense compact row listings. * Fast Filter & Search: Hardware-accelerated search across titles, URLs, and custom tags with smooth 60/120 FPS animations. * Interactive Tag Management: Create, edit, and filter custom category tags with haptic-enabled context sheets. * Offline Storage: Snapshots and metadata are preserved locally on-device in a Room SQLite database. * System Share Sheet Integration: Save links directly from Google Chrome, Firefox, or any app in a single tap. * Smart Clipboard Detection: Auto-detects URLs on the system clipboard for one-tap bookmarking. * 100% Privacy & Zero Trackers: Fully open source with no advertising SDKs, tracking pixels, or remote telemetry. Remote previews are optional and off by default, keeping bookmark data strictly on-device.
