copymanga-copy20: Chinese manga sources for Mihon, Tachiyomi and Suwayomi

What copymanga-copy20 is for

This repository is a source distribution, not a reader. It packages extensions that let a Mihon, Tachiyomi or Tachidesk/Suwayomi client browse and read Chinese-language manga from four sites: Copymanga (拷貝漫畫), vomic (vomic漫), Manwa2 (漫蛙2) and Baozimanhua (包子漫畫). The README states the project supports 拷貝漫畫/vomic/包子漫畫, and the release notes add Manwa2 as its own module with its own version line.

It exists because these sites are not in the mainstream extension index that most Mihon users subscribe to. If you read Chinese-language series and keep your library in a Tachiyomi-lineage app, this is the piece that puts those catalogues inside the app you already use. The audience is narrow on purpose: readers who want Chinese sources, not a general-purpose extension bundle.

The repository is not archived, and the last push was on 2026-09-20. That date is the only maintenance signal available here. The README does not describe a release cadence, a support window or a deprecation policy for any of the four modules, so there is no published promise about how quickly a broken source gets fixed. Treat the community channels as the place where that gets negotiated, not the repository files.

Four modules, one repository URL

The layout is the standard extension-repo shape. At the top level there is apk/, icon/, smali/, page/, index.html, index.json, index.min.json and repo.json. The client fetches the index, reads the list of extensions and their APK download locations, and installs from there. The smali/ directory holds the sources, which is why the primary language is listed as Smali: these extensions are written in the same Android bytecode-adjacent style that Tachiyomi extensions have historically used.

Each module carries its own version. Copymanga is at v1.4.85, vomic漫 at v1.4.4, 漫蛙2 at v1.4.8, and 包子漫畫 at v1.4.3. Releases are tagged per module, for example manwayu-v1.4.8 and v1.4.85-copymanga, so a client can update one source without touching the others. That matters when a site changes its markup: a fix for Manwa2 does not force a reinstall of a Copymanga build you are happy with.

The Copymanga module has grown beyond a plain scraper. The release notes for v1.4.85 state that it is compatible with recent Tachidesk/Suwayomi builds, that the API domain can be switched in the extension settings to reach 熱辣漫畫, and that a logged-in user can pull the source site's account cabinet (書櫃) to migrate favourites. vomic漫 requires a login before use and supports filters for theme, sort order, serialisation status, creation type and multiple rankings, plus chapter comments and simplified/traditional conversion. 漫蛙2 advertises multi-line image sources and all of the source site's filter methods, with no login required. 包子漫畫 supports theme, region and serialisation status filters and a banner-removal option.

The v1.4.85 notes also record a smaller change worth knowing about: WebView links are fixed to the desktop version and the client-type setting was removed. If you had configured that setting, it is gone, and the extension now makes the choice for you.

Installing via the repository URL, then a first read

The README gives two paths. The first is the repository update address, which you paste into your client's extension repository settings. The second is downloading an APK from the Releases page if the repository route fails.

The repository address is a single raw JSON URL:

https://raw.githubusercontent.com/LittleSurvival/copymanga-copy20/repo/index.min.json

In Mihon or Tachiyomi, open the browse/extensions section, add a repository, and paste that URL. The client fetches index.min.json, lists the four extensions, and offers an install button for each. If the fetch fails, the README's fallback is to download the APK for the module you want from Releases and install it directly. The two paths are not equivalent: the URL route gives you per-module updates inside the client, while a manually installed APK is yours to replace by hand.

After installing Copymanga, open the extension's own settings before browsing. The release notes place the API domain switch there, which is what moves you between Copymanga and 熱辣漫畫. The account cabinet option also lives behind a login. For vomic漫 the README is explicit: log in through the extension settings first, otherwise the source will not work as intended.

The comment-blocking feature is configured with one regular expression per line. The release notes say each line is one rule, that it applies to both the overall comments and the end-of-chapter comments, and that changes require clearing the chapter cache. An invalid regex is rejected with a prompt rather than saved. The cache requirement is the part people miss: editing the list without clearing the chapter cache leaves the old rendering in place, and the extension will look as if it ignored your rules.

Where it breaks: downloads, five-page limits and account state

The Q&A section is unusually honest about failure modes, and they cluster around local state rather than the network.

The first is old single-volume downloads. If a previously downloaded file can no longer be matched, the README says the only fix is to remove the title from your library, run 進階 > 清除資料庫, refresh the chapters, then run 進階 > 重新索引下載位置. The same note warns that this clears reading history, and the project does not recommend it. That is a real cost: a maintenance operation on the download index can destroy the record of what you have read, and there is no documented way to back that record up first.

The second is ordinary chapter files that cannot be matched, which the README attributes to simplified/traditional conversion producing a filename that no longer lines up. There is no documented workaround beyond that diagnosis, so the practical advice is to avoid switching conversion settings on a title you have already downloaded.

The third is the five-page ceiling. If a chapter stops after five pages, the README's advice is to change the User-Agent, both in the extension settings and in Mihon's own UA setting. That points at server-side filtering rather than a bug in the extension, and it means the fix is environmental and can regress whenever the source site changes its rules. Note that it is a two-place change, and setting only one of them may not be enough.

Finally, account state is load-bearing for Copymanga's cabinet migration and for all of vomic漫. Logged-out users of vomic漫 get nothing; the README says to log in first. Anyone who wants a purely anonymous reader should treat vomic漫 as unavailable. Copymanga is more forgiving, since the cabinet import is an optional migration aid rather than a prerequisite for browsing.

How this differs from Keiyoushi and a general extension index

The obvious alternative is the Keiyoushi extension repository, which is the default source list most Mihon users subscribe to. The difference is scope and language. Keiyoushi is a broad, community-maintained index covering many languages and many sites; copymanga-copy20 is a small repository that targets four Chinese-language sources and nothing else.

That narrowness cuts both ways. A small repo can iterate on one site's quirks quickly, which is what the Copymanga module's API-domain switch and cabinet import look like. It also means the whole catalogue depends on one maintainer's willingness to keep four modules current. The release history shows Copymanga at v1.4.85 in early September 2026 and 漫蛙2 at v1.4.8 later that month, so the modules do not move in lockstep, and a reader who depends on all four is exposed to whichever one lags.

A second difference is the Smali source format. Extensions in this style are harder for an outside contributor to patch than a Kotlin or Java extension, and the repository does not ship a build guide in the README. If you are choosing between this and a source that publishes readable sources, the trade-off is maintenance reach against the specific catalogues you get.

If you only read Copymanga and nothing else, the repository is still the right container, because it also carries vomic, Manwa2 and Baozimanhua and updates them independently. There is no separate Copymanga-only repository described in these files, so subscribing here costs you nothing extra in client configuration.

Licence, upgrade cost and what the repository does not say

There is no licence identifier in the repository metadata, and the README does not state terms for the extension code or for the APKs published under Releases. Without a licence file, the default position is that no permission is granted, so redistributing or bundling these APKs is not something the project has clearly authorised. This is a description of the repository's contents, not legal advice; if redistribution matters to you, ask in the community channels the README lists.

The upgrade path is the one you configured at install time. If you subscribed with the repository URL, the client polls index.min.json and offers new versions per module. If you installed APKs manually, you re-download from Releases. The README does not document rollback, and it does not describe how to pin an older module version, so a bad release leaves you waiting for the next one or hunting through Releases by hand. For a source that depends on a third-party site's API, that is the weakest part of the setup: the failure mode you are most likely to hit is a source breaking after a site change, and the recovery you have is a new release, not a downgrade.

The README also does not document a support window, a compatibility matrix beyond the note that Copymanga v1.4.85 works with recent Tachidesk/Suwayomi builds, or a policy for when a source site changes its API. The community links (Telegram, two QQ groups, Discord, and the documentation page at littlesurvival.github.io/copymanga-copy20) are where that information would appear.

Editorial conclusion

Adopt copymanga-copy20 if you read Chinese-language manga in Mihon, Tachiyomi or current Suwayomi builds and want Copymanga, vomic, Manwa2 and Baozimanhua from one repository URL. Skip it if you need English or licensed sources, or if you rely on long-term local archives, because the README's own recovery path for unrecognised single-volume downloads requires clearing the database and wiping reading history. Before trusting it with a library, subscribe with the repo URL, open the Copymanga extension settings and confirm the API domain, then verify that the account cabinet import and the comment-blocking regex list behave the way the release notes describe.
