Short answer: TachiyomiAZ (“AZ”) is one of the oldest names in the Tachiyomi fork family, and its current line (v8.9.1-AZ, August 2026) is — by its own README — a fork of Mihon. It aims to gather features and fixes from across the fork ecosystem (its lineage runs through TachiyomiEH) into one app, and it requires Android 8.0 or later.
A quick history, because the name confuses people
AZ predates Mihon: it was a feature fork in the original Tachiyomi era, and other forks (including early SY) drew from it. After Tachiyomi ended in January 2024, AZ rebased onto Mihon like most survivors. So “TachiyomiAZ” today is best understood as “Mihon, plus the AZ team’s selection of extra features and fixes” — the same repositories, extensions and backup format as the rest of the modern family.
Who AZ suits
- Long-time Tachiyomi users who used AZ before 2024 and want the closest continuation of that experience.
- Readers who like the Mihon base but want a fork team’s curation of features gathered from sister projects (historically including J2K-style touches).
- Anyone whose device runs Android 8.0+ — older Android versions are not supported by the current line.
AZ vs the alternatives
Against stock Mihon, AZ trades the main project’s release cadence for extra bundled features. Against SY, the difference is emphasis: SY pushes its own headline features (recommendations, entry merging — see the SY guide), while AZ positions itself as a broad collection. There is no wrong answer; all three read the same libraries. Compare the philosophies in our Android reader roundup.
Installing AZ
- Back up your library first (.tachibk guide) — and mind the 0.21.x restore window described in the migration guide.
- Download AZ only from its official GitHub repository (
az4521/TachiyomiAZ). - Add extension repositories (guide), install extensions, then restore your backup.
