Boundless is a manga, manhwa, comic, and novel reader built to browse, track, and read across your own library, all in one continuous interface. Bring in your own files (CBZ, PDF, text, Markdown) or connect a self-hosted Komga server, and plug in user-built sources to extend your library further. Everything can be read as; paged, vertical, or webtoon, with automatic chapter loading and prefetch so the next one is ready before you get there. An account is optional. Sign in to sync your library, history, and progress across devices, or skip it and read fully offline with local files. READING, YOUR WAY • System, Serif, Rounded, Monospaced, or a dyslexia-friendly font, with full spacing control • Auto-scroll, custom tap zones, and tap cooldowns • Nine accent colors, a true black Void theme for AMOLED, and animated backgrounds BUILT FOR APPLE Genuinely native on iPhone, iPad, and Apple Silicon Mac, not one layout stretched across all three. FAMILY CONTROLS Blur or hide covers by rating or genre, and lock restricted content behind a PIN. Full backup and restore, offline downloads, and reading history grouped by day. Boundless doesn't host or supply content itself: what you read comes from your own files, your own server, or the sources you choose to plug in.
