Kotatsu vs Mihon — Which One to Use
Both apps are free, open source, and built for serious manga readers on Android. They solve the same problem but take completely different approaches. Picking the wrong one means either a frustrating setup experience or hitting a source gap six months in. This comparison cuts through the surface-level stuff and focuses on what actually matters day to day.
Both apps were used on real Android devices for this comparison. Every claim here is based on hands-on testing, not feature lists from their documentation.
The Core Difference
This is the one thing you need to understand before anything else: Kotatsu bundles sources inside the app, Mihon doesn’t. When you install Kotatsu, over 1000 manga sources are ready to use immediately — no additional installs, no configuration, just open and browse. When you install Mihon, you start with zero sources. You have to find, download, and install each source as a separate extension plugin before you can read anything.
That single architectural difference drives almost every other comparison between the two apps. Setup time, maintenance burden, total source count, update reliability — all of it flows from whether sources are built in or installed separately. Neither approach is objectively better. They’re optimized for different types of readers.
If you want to start reading in two minutes with no configuration, Kotatsu wins. If you want maximum flexibility and don’t mind spending time building your setup, Mihon eventually gives you more. That’s the real choice here.
Quick take: Kotatsu is for readers who want to start reading immediately. Mihon is for readers who want maximum control over every source they use.
Sources and Coverage
How Kotatsu Handles Sources
Kotatsu’s 1000+ sources update with the app itself. When the Kotatsu team fixes a broken source or adds a new one, it comes through as an app update. You don’t have to do anything. Dead sources get removed, new ones get added, and your source list stays current without any manual work. The tradeoff is that you have no control over which version of a source extension is installed — you get whatever the Kotatsu team ships.
Source quality across the 1000+ is uneven. Some load fast and update daily. Others are slow or go weeks without new chapters. The Explore tab shows an Updated filter on each source catalog that tells you when content last changed — use this to identify which sources for your genres are actually active versus nominally available.
How Mihon Handles Sources
Mihon’s extension library is community-maintained and larger in total count than Kotatsu’s built-in catalog. You browse available extensions from inside the app, find the source you want, and install it as an individual plugin. Each extension can be updated independently, which means a broken source can be fixed faster than waiting for a full app update. The downside is that you’re responsible for finding, installing, and maintaining every source you use. On a fresh install with no prior Mihon experience, building a functional source library takes anywhere from 20 minutes to an hour depending on how many sources you want.
Setup and Daily Use
Getting Started
Kotatsu is ready in under two minutes. Download the APK, install it, select your language sources on the welcome screen, open Explore. Your first manga chapter is accessible before you’ve had time to think about what app you wanted to use. There’s nothing to configure to get basic functionality working.
Mihon takes longer. After installing, you go to the Extensions section, search for the sources you want, install each one, then navigate to that source’s catalog and find your title. If you already know exactly which sources you use and have them bookmarked, you can set up Mihon reasonably quickly. For a first-time user with no prior setup experience, it’s a steeper start.
Long-Term Maintenance
Over time, sources break. A site changes its structure, the source extension stops working, chapters stop loading. In Kotatsu, source fixes come through app updates — you update the app and the fix is in. In Mihon, broken extensions need to be updated individually. You’ll get a notification that an update is available for an extension, and you update it from the Extensions tab. More granular control, but also more ongoing management. Most active Mihon users check their extension updates once or twice a week as part of their normal routine.
When a Source Breaks Mid-Series
Both apps let you switch sources for a specific title without losing reading progress. In Kotatsu, tap the three-dot menu on the title’s detail page and select the option to change source. In Mihon, the process is similar through the manga info screen. Your read chapter history carries over in both cases. The difference is that Kotatsu has 1000+ alternatives to search from immediately, while Mihon’s alternatives depend on which extensions you have installed.
Updating the App Itself
Neither app is on the Play Store, so updates don’t come automatically. For Kotatsu, check this site or the GitHub releases page for new versions — download the APK and install it over the existing app. For Mihon, updates are available through their GitHub releases page as well. In both cases, installing an update over the existing app preserves all your data. The process takes about two minutes each time.
Reading Experience Compared
Both apps offer the same four core reading modes: standard, right-to-left, vertical, and webtoon. Both save reading mode per title. Both have color correction, page scaling, and bookmark support. On reading experience alone, there’s no meaningful difference between them for most readers.
Where they diverge is in the reader settings menu depth. Mihon has more granular control over certain display settings — crop options, scaling behavior, and page transition animations have more configuration options. Kotatsu’s reader is cleaner and less overwhelming, which is better for readers who just want to read without digging through settings. If you’re the type to spend an hour tweaking display settings until they’re perfect, Mihon gives you more to work with. Most readers will be satisfied with Kotatsu’s options.
Tracking and Library Features
Both apps connect to AniList, MyAnimeList, Kitsu, and Shikimori. Both support offline downloads. Both have backup and restore functionality. Both maintain a reading history and support custom collections. On paper, feature parity is high between the two apps in this area.
The practical difference is in backup compatibility. If you have a Tachiyomi backup from before it shut down, both Kotatsu and Mihon can restore from it. Mihon has tighter compatibility since it’s a direct Tachiyomi fork — complex library structures with many custom categories tend to restore more cleanly in Mihon. Kotatsu restores the core data reliably but may not preserve every Tachiyomi-specific custom category label perfectly.

Frequently Asked Questions
Which One to Download
Start with Kotatsu. It works out of the box, covers 1000+ sources without any setup, and the reading experience is clean and fast. For the overwhelming majority of manga readers on Android, Kotatsu handles everything without gaps.
Move to Mihon — or add it alongside Kotatsu — if you hit a specific source that isn’t in Kotatsu’s built-in catalog and you can’t find the same title on a different source. That’s the one real scenario where Mihon’s extension system gives you something Kotatsu can’t.
