KurobaEx is a fast Android app for browsing imageboards, such as 4chan and 8chan. It's a fork of Kuroba. This fork provides lots of new features:
-
New technological stack (Kotlin, RxJava/Coroutines, Room etc).
-
On demand content loading (includes prefetching, youtube videos titles and durations fetching, inlined files size fetching etc).
-
Third-party archives support.
-
New thread navigation (tabs).
-
New in-app navigation (bottom nav bar).
-
New bookmarks (they were fully rewritten from scratch, now use way less memory, don't use wakelocks, show separate notifications per thread (and notifications can be swiped away).
-
Edge-to-edge theme support.
-
New database.
-
4chan global search support.
-
Fully dynamic themes with Android Q Day/Night mode support.
-
Per-site proxies.
-
Ability to attach multiple media files to reply, attach media files that was shared by external apps (even by some keyboards), attach remote media files by URL, etc.
-
New image downloader. Allows downloading images while the app is in background, retrying failed to download images, resolving duplicates, etc.
-
New posting. Posting code was moved into a foreground service which now allows stuff like using automatic captcha solvers (2captcha API) seamlessly or queueing multiple replies in different threads (only one reply per thread).
-
New Media Viewer. It was rewritten from scratch and now lives in a separate activity. It now also supports stuff like viewing links to media files shared into the app.
-
Thread downloader with ability to export threads as HTML pages with all downloaded media.
-
Composite catalogs (ability to combine multiple boards of any available sites (except archives) together into a single catalog).
-
Mpv video player (downloadable).
-
Bookmark groups with ability to setup regex matchers to automatically move newly created bookmarks into them.
-
Automatic captcha solver for 4chan captcha (See https://github.com/K1rakishou/4chanCaptchaSolver)
-
Lots of other tiny improvements.
