What Happened to Tachiyomi.org? (Explained)

Tachiyomi.org shut down in January 2024 after its developers received a cease-and-desist letter from Kakao Entertainment, a South Korean media company. The core team stopped active development, took down official repositories, and the community moved on to successor apps like Mihon. Here’s the full story, verified against the official record.

What Happened to Tachiyomi.org?

On January 13, 2024, the Tachiyomi development team posted an announcement — informally titled “It’s Joever” — confirming the core project would no longer be actively developed. According to Wikipedia, the developers had received a cease-and-desist letter from Kakao Entertainment demanding they destroy the project and all of its forks. In response, the core team removed the project’s repositories and stopped providing extension sources for the app.

The official Tachiyomi GitHub organization reflects this today — it remains visible as a verified, archived record of the project’s history rather than an actively maintained page.

Why Did This Happen?

Tachiyomi itself was a neutral tool — a manga reader that connected to third-party sources chosen by the user, and it never hosted any content directly. The issue was that some of those third-party sources included sites hosting content Kakao owns the rights to, such as certain manhwa titles.

Kakao first contacted the Tachiyomi team on January 2, 2024, requesting the removal of specific infringing sources. The team complied within days, releasing new versions without any pre-loaded extensions. But Kakao continued pushing, and rather than risk further legal exposure to the volunteer developers behind the project, the core team chose to stop development entirely.

Is Tachiyomi.org Still Online?

The domain’s official repositories and social accounts were shut down as part of the announcement. Any site currently using the tachiyomi.org name or claiming to be a continuation of it is not run by the original developers — the team explicitly warned users of this in their farewell statement, noting that anything new claiming to be a “successor” has no relation to the original project unless proven otherwise.

What Replaced Tachiyomi.org?

Within days of the shutdown, community developers began building on the last available version of the open-source code. The most notable result is Mihon, built by former Tachiyomi contributors and hosted openly on GitHub. Other forks, including TachiyomiSY and TachiyomiAZ, have since rebased onto Mihon rather than the original, now-frozen codebase.

Can I Still Use the Original Tachiyomi App?

Yes. Because the app never hosted content itself and the last released version still functions, existing installations were not disabled or remotely affected. What changed is that it no longer receives updates, security patches, or new extension support from the original team. For anyone wanting continued development, Mihon is the direct successor built by the same community.
