Open Source Trakt.tv Alternatives

SeriesGuide is an Android app for anyone who watches a lot of TV and wants a reliable way to track what they've seen, what's airing next, and what's on their watchlist. It pulls data from TMDb to keep show and movie information current.

At its core, it's a personal viewing log. You mark episodes as watched, follow release schedules, and manage a list of shows and films you plan to get to. If you've ever lost track of where you left off in a series, or forgotten whether you've already seen a movie, this solves that problem.

The app is built specifically for Android, so it fits naturally into the mobile experience rather than being a web tool bolted onto a phone. It's a solid open source TV Time alternative for people who prefer not to rely on closed, account-heavy platforms for something as simple as tracking their watch history.

Because it's open source, the code is publicly available and the project is community-supported. There's no black box around how your data is handled, and the app doesn't depend on a proprietary backend that could disappear or change terms without notice.

Showly is a TV show and movie tracking app for Android and iOS, built around a clean interface and tight Trakt.tv integration. It's aimed at anyone who wants a single place to manage what they're watching, what they've watched, and what's coming up next.

The core loop is straightforward: browse trending and curated titles, mark episodes and movies as watched, and build out a collection over time. Showly separates your Watchlist (things you plan to watch) from your Collection (things you've seen), which keeps your library organized without much manual effort.

Key capabilities:

• Trakt.tv sync keeps your history, collection, and watchlist consistent across devices and compatible apps
• Episode tracking shows your progress through a series and surfaces what's coming up next
• Discovery tools surface trending titles, personalized recommendations, and less obvious picks based on your tastes
• Home screen widgets let you check upcoming episodes without opening the app
• Cross-platform availability on both iOS and Android, free to download

The Trakt.tv integration is the standout feature for serious trackers. Trakt is a widely used open platform for logging watch history, so connecting Showly to it means your data isn't locked into a single app. You can switch clients or use multiple apps without losing your history.

With over 80,000 users, Showly has built a following largely on its interface quality. The UI is consistently cited as one of its strengths, which matters in a category where many alternatives feel cluttered or dated.

Tonkatsu Box is a free, open-source media tracker for people who want one place to manage everything they watch, play, and read. It runs on Windows, Linux, and Android, and covers a wide range of media types: retro games, movies, TV shows, animation, anime, manga, visual novels, and books.

The core idea is unified collection management. You can mix any media type into a single collection, switch between grid and list views, and track status across four states: In Progress, Completed, Planned, or Dropped. For TV shows and anime, it tracks individual episodes. Everything can be rated on a 1–10 scale with personal notes attached.

Finding titles is backed by a broad set of databases:

• Games: IGDB, RetroAchievements, SteamGridDB
• Movies and TV: TMDB, Kinorium
• Anime and manga: AniList, MangaBaka, MyAnimeList
• Visual novels: VNDB
• Books and comics: OpenLibrary, Fantlab, Google Books, ComicVine

Beyond basic tracking, it has a few features that set it apart from a simple TV time alternative. Visual Boards let you arrange posters on a free-form canvas, add text notes and links, and draw connections between items. Tier Lists support drag-and-drop ranking into S/A/B/C tiers, and a Mood Grid lets you lay out picks on a customizable N×M board. Both export as PNG.

Importing existing data is well-covered. You can pull in libraries from Steam, Trakt.tv, RetroAchievements, MyAnimeList, AniList, and Kinorium. Sharing works through two export formats: a lightweight .xcoll file (requires internet for images) and a self-contained .xcollx package that works fully offline. Friends can import and fork your lists directly.

The app is built with Flutter and uses SQLite locally, so your data stays on your device. No account required, no cloud dependency. API keys for IGDB, TMDB, and SteamGridDB are optional; the app works without them out of the box.
