Sozo is an open-source Flutter app for finding, watching, reading and keeping track of films, series, anime, manga and light novels. The name is Japanese for creation, imagination.
It runs in three modes — Video, Manga and Novel — each with its own sources and its own player or reader. On top of that: an Android TV interface, Chromecast, torrents, watching together, and real desktop builds.
Sozo hosts nothing. It is a client: you choose which sources to install, and it plays what they return. See How sources work and the Disclaimer.

This is the part that decides whether anything plays, so it is worth stating plainly.
Sozo ships with no content of its own. What it ships is the runtimes; you install sources into them.
| Ecosystem | What it is | Where it runs |
|---|---|---|
| Sozo | Our own cloud sources, served by the backend | Server |
| CloudStream | .cs3 plugins from CloudStream repositories |
On the device, in a class loader |
| Aniyomi | Anime extension APKs | On the device, in a class loader |
| Manga | Mihon/Tachiyomi extension APKs | On the device, in a class loader |
| Mangayomi | JavaScript sources, including every novel source | On the device, in a JS runtime |
Add a repository from Profile → Sources → Add source, install what you want, and pick it from the source switcher on the home screen. Novels come from Mangayomi repositories specifically — that is the only ecosystem that publishes them.
A source that stops working almost always stopped working on its own: sites move, shut down, or start blocking. Sozo now says which of those happened rather than printing the exception, and Profile → Sources → DNS can route name lookups through Cloudflare, Google, Quad9, AdGuard or Mullvad for the case where a provider blocks a site by refusing to resolve it. That is not a VPN: it does not hide your traffic and does not change your IP.
| Layer | What it uses |
|---|---|
| Framework | Flutter + Dart |
| State | flutter_bloc · get_it (DI) · go_router |
| Player | media_kit (libmpv) + the platform video_player |
| Storage | Hive + flutter_secure_storage |
| Networking | Dio + a cookie jar |
| Extension runtimes | DexClassLoader (Aniyomi, Manga, CloudStream) + a headless WebView for JavaScript sources |
| Backend | Node.js (sozo-backend) |
The architecture is feature-first clean architecture: lib/core/ for what everything shares, and lib/features/<feature>/{data,domain,presentation} for the rest.

Does Sozo host any content?
No. Sozo is a client and a tracker. It stores nothing, distributes nothing, and does not run the extensions it loads. See the Disclaimer.
There are no sources after I install it. Is it broken?
No — that is the starting state. Extension sources are installed, not built in. Open Profile → Sources → Add source, add a repository, and install the ones you want. See How sources work.
Which APK should I download?
arm64-v8a on any modern phone. If you are not sure, or Android says "package not compatible", take universal.
macOS says the app is damaged and will not open
The DMG is not signed with an Apple certificate (that costs $99 a year). Run this once:
xattr -dr com.apple.quarantine /Applications/Sozo.appOr right-click Sozo.app in Applications → Open → Open.
A source stopped working, or a video will not play
Almost always the source itself rather than the app: sites move, shut down, or start blocking. The error on screen now says which. Two things worth trying first — pick another source for the same title with Try another source, and set Profile → Sources → DNS to Cloudflare if your provider blocks by DNS.
If it still fails, report it with the source not working template and include the exact message.
Is the DNS setting a VPN?
No. It only changes who answers "what is the address of this host". Your traffic takes the same route to the same servers from the same address. It helps when a site is blocked by DNS and does nothing when it is blocked by address.
Is Sozo free?
Yes — free and open source under GPL-3.0. No ads, no subscription.

Important
Sozo is a client and a tracker. It does not host, provide, distribute or operate any media content. No content ships inside the app.
- Sources — Sozo works with third-party sources on the open internet and with extensions the user installs themselves. Those sources are not made, controlled or endorsed by Sozo.
- Responsibility — Using the app, and any third-party service reached through it, is entirely the user's responsibility. Users must comply with the laws of their own country and with copyright and intellectual-property requirements.
- No liability — The developer is not liable for misuse of the app, for anything that follows from it, or for breaches involving third-party services.
- Legal requests — Complaints about a particular source or extension belong with the owner of that source, not with Sozo. A takedown request against this repository can only concern the code in this repository.
- Official APIs — Sozo integrates only with the official, public APIs of services such as AniList, MyAnimeList and TMDB.

What that means: you may fork, modify and redistribute Sozo — but a modified version has to stay open source under GPL-3.0 too. You cannot turn Sozo into a closed-source or ad-supported app and sell it on.
If Sozo is useful to you, ⭐ star it. That helps the project more than anything else.
