Prisma

High-performance, modern cross-platform client for Booru imageboards, creator archives, manga, and light novels.

English • Русский

Prisma is a unified, resource-optimized multimedia viewer and catalog reader built with Flutter. It brings together popular booru imageboards, creator galleries, manga repositories, and light novel libraries into a cohesive, fluid Material 3 interface across Android, Linux, Windows, and macOS.

• Adaptive Layouts: Pinterest-style masonry grid, fixed aspect ratio grids, and compact list modes.
• Hardware-Accelerated Media Player: High-definition video player powered by media_kit (mpv), featuring gesture-driven controls, audio track toggles, and seamless looping.
• Deep Zoom & Notes Overlay: Interactive high-resolution viewer with pinch-to-zoom, translation notes overlay, and multi-asset carousels.

• Integrated Catalogs: Direct access to titles from MangaDex, MangaLib, and RanobeLib.
• Versatile Reading Modes:
  • Webtoon: Smooth vertical continuous scroll with hardware-accelerated image pipeline.
  • Manga Reader: Traditional right-to-left (RTL) and left-to-right (LTR) page-by-page viewing.
  • Light Novel Reader: Dedicated typography engine with custom font scaling, line height, and reader color schemes.
• Personal Library Management: Track reading status (Reading, Plan to Read, Completed, On Hold, Dropped) with automated chapter progress synchronization and offline reading support.

• Sub-Millisecond Tag Autocomplete: Instant search suggestions across millions of booru tags.
• Complex Query Syntax: Multi-tag queries, boolean exclusions (-tag), exact matching, rating filters, and source switching without resetting parameters.
• Artist Hub: Explore creator portfolios with direct integration into creator platforms.

• Sliding-Window Memory Management: Active post carousel isolates memory consumption to immediate adjacent pages ($\pm 1$), aggressively evicting distant decoders from RAM.
• Smart Memory GC & Watchdog: Proactively responds to system memory pressure signals and keeps application footprint under tight control during extended browsing sessions.
• Built-in Resource Monitor & Floating HUD: Real-time diagnostic overlays displaying physical RSS RAM, Peak usage, image cache allocations, process CPU %, and engine frame rates (FPS).

• Configurable Downloader: Template-based file organization (e.g. {Artist}/{ID}) with integrated download manager.
• Cross-Service Bookmarks: Local collections, favorite posts, and Pawchive two-way synchronization.
• Strict Content Filtering: Global blacklist, whitelist, and discreet blur filters for sensitive material.
