Why Hentai Reader

Built for performance. Viewport-aware loading, browser-native off-screen rendering containment, bounded shared caches, and directional prefetching keep long galleries responsive without duplicate downloads.
Works everywhere. Full desktop controls (wheel paging, keyboard, click zones) alongside first-class touch support — tap zones, swipe paging, pinch-zoom, and an auto-hiding UI — so it feels native on both.
One reader, every site. A single adapter-based core delivers the same reading experience across sites; new sites plug in without touching the reader.
Resilient by design. Automatic retry with node switching recovers failed loads, and a load-aware scroll gate keeps you from overshooting onto still-loading pages.

Features

Infinite Scroll Mode — Converts multi-page galleries into a continuous vertical scroll with auto-prefetching, while preserving native page metadata (tags, titles, comments). Toggle on the fly with instant reload.
Immersive Reader Mode — A distraction-free, full-screen viewer with keyboard, wheel, tap, and swipe navigation, plus a virtual-scrolling thumbnail panel for quick jumps.
Dynamic Two-page View — Enabled by default on wide screens: adjacent portrait pages form a zoomable spread, with selectable left-to-right or manga-style right-to-left page placement. Landscape pages and narrow screens safely remain single-page.
Performance Engine — Foreground-first image scheduling, staged 5/2 directional prefetch, viewport-aware loading, lease-protected shared tasks, and bounded caches keep current pages fast without duplicate work.
Desktop & Touch — Full desktop controls (wheel paging, keyboard, click zones) plus first-class touch: edge tap-to-page, swipe paging, pinch-zoom, and a timed auto-hiding UI for one-handed reading.
18comic Decoding Engine — Canvas-based descrambling runs through the shared priority scheduler, reuses managed image tasks, and releases Bitmap, Canvas, Blob, and Object URL resources predictably.
Smart Anti-Blocking — Domain feature-matching and redirect following keep the script working on sites like 4KHD that frequently change domains.
Robust Loading — Automatic retry with hath-node switching for failed images, a unified status HUD for load progress, and a load-aware scroll gate that stops paging at unloaded pages.
Auto Play — Hands-free slideshow mode with a five-second default, direct 1–60 second input, and five-second adjustment buttons. A loading page gets one bounded five-second grace period and cannot block playback forever.
