Features of Kotatsu:

Discover from many catalogs: Kotatsu brings together more than one thousand community sources. You can search by title, genre, or tags, and you can use a random picker to find something new. This wide coverage makes it easier to compare availability and quality across catalogs.

Read online or save chapters for offline: You can stream chapters immediately or download single chapters and full series for offline reading. Kotatsu includes a careful downloader with throttling to reduce strain on sources. Therefore, your downloads are less likely to fail or get blocked.

Customize the reader to your preference: Kotatsu lets you adjust orientation and scaling so pages fit your screen the way you like. You can tweak contrast and color correction for better readability. You can also navigate with taps or volume keys for simple one-handed use.

Track progress with popular services: It integrates with MyAnimeList, AniList, and Shikimori. You can sign in to your accounts and keep chapter progress synced. This makes it easier to continue reading on any device while your lists stay up to date.

Sync your library across devices: The app supports cross-device synchronization for your library and reading position. You can move between phones and tablets and continue exactly where you stopped. In addition, your favorites and history remain aligned.

Strengths of Kotatsu:

Reading History: Every title you tap gets logged in the History tab automatically. Want to jump back to where you stopped? One tap. No digging around, no bookmarking manually. You can wipe the history from the Feed menu anytime.

Bookmarks: Bookmarks save a specific page inside a chapter — not just your last position, but an exact panel. They show up in Favourites and survive restarts. Export a backup, and they come with it. Useful for saving a plot twist panel or an art spread you want to find again.

Feed Updates: Feed shows every new chapter across all your saved titles, refreshed each time you open the app. Filter it to show only recent updates or clear it completely from the three-dot menu. That same menu holds Incognito toggle, manual refresh, and Settings. Readers following 20+ ongoing series live in this tab.

Multi-Languages: Sources cover 15+ languages: English, Spanish, French, Portuguese, Indonesian, Japanese, Russian, Chinese, and more. You pick which ones to turn on during setup. Change them anytime in Settings. Language tags are visible on each source, so you don’t end up in the wrong catalog.

Open Source Platform: The full Kotatsu code is on GitHub under KotatsuApp. Anyone can check it for trackers or malicious behavior — and many have. When a source breaks, the community usually patches it within days. You can watch the changelog, file bugs, or contribute code if you’re into that.

User Reviews of Kotatsu:

Needs some work, but I like it. I actually prefer its UI. It feels smoother than Tachi.

This is the only app which has the option for offline downloads, this is the only open source app which gives you the opportunity of freely reading all manga/manhwa/comics and etc cz this app supports almost every available sites.... This is the one & only open source app which is still working like a charm while many other apps got shut down after few months.

It's faster in terms of loading pages but it's a bit clunky if you load in webtoon with large amount of pages. It's search function is also bad and often times doesn't show everything that's supposed to show.

I've been trying it out since the Tachiyomi snafu started last week; and I find there is a lot that I wish Tachi had. Kotatsu feels smother when reading from the library, or just searching for new stuff with the extensions. On the other hand it is missing extensions I use with Tachiyomi; and it has a habit to throw up an error if you accidentally pull down and reload a search page making it not reload that extension again at all until you close out of the app. Its clearly a work in progress and with a bit more elbow grease it could be great.
