Why Is Syncing Your Anime Watchlist Across AniList, MAL, and Kitsu So Frustratingly Hard?
Managing anime lists across multiple trackers is a known pain point. Here's why sync fails, which tools actually work, and the best strategy for keeping your lists in one place.
The Multi-Tracker Problem Is Real
You started tracking on MyAnimeList. Then you heard AniList has a better API and a modern interface. You tried Kitsu for its cross-media simplicity. Now you have three lists, and they don't match. This is the multi-tracker problem — and it's one of the most discussed frustrations in r/MyAnimeList and r/anilist right now (Reddit r/MyAnimeList, 2024).
The root cause is structural: each tracker uses a different database, different ID system, and different API. AniList's GraphQL API is more flexible than MAL's REST API, but MAL has the largest community and the most representative scores. Kitsu bridges anime and manga but has a smaller library. None of them talk to each other natively (AniList, 2026).
Key Takeaways
- Each tracker has a different ID system — syncing requires a mapping layer.
- MAL-Sync is the most mature tool for cross-platform list syncing.
- AniSync offers automatic progress tracking across multiple services.
- The best strategy is to pick one primary tracker and sync the rest.
Why Can't the Trackers Just Talk to Each Other?
The short answer: they can, but it's complicated. Each tracker stores anime and manga by its own internal ID. AniList's ID for "Attack on Titan" is different from MAL's ID, which is different from Kitsu's. To sync between platforms, a tool needs a universal ID mapping — and that mapping has to be maintained as new titles are added constantly (MALSync, 2026).
MAL-Sync solves this by integrating MyAnimeList, AniList, Kitsu, and Simkl into a single extension. It uses the AniList GraphQL API and MAL's REST API to map entries between platforms. When you mark an episode as watched on Crunchyroll, MAL-Sync can automatically update your list on both MAL and AniList (MALSync, 2026).
**** MAL-Sync has 2,918 GitHub stars and 358 forks as of July 2026, making it the most popular anime list synchronization tool. It supports Chrome, Firefox, and userscript formats.
The Best Tools for Multi-Tracker Sync
MAL-Sync (Extension + Userscript)
MAL-Sync is the most comprehensive solution. It integrates MyAnimeList, AniList, Kitsu, and Simkl into various anime streaming websites, with auto episode tracking. Supported sites include Crunchyroll, Gogoanime, and other streaming platforms (MALSync, 2026).
Pros:
- Auto episode tracking across platforms
- Supports 4+ trackers simultaneously
- Works on most anime streaming sites
- Both extension and userscript formats
Cons:
- Requires manual setup per site
- Doesn't support Anime Planet or other smaller trackers
- Occasional sync conflicts when both platforms are updated simultaneously
AniSync (Add-on)
AniSync is a lighter alternative that syncs watch progress to MyAnimeList, AniList, and Simkl automatically. It triggers tracking when an episode loads, not when it finishes — giving you more accurate progress data (AniSync, 2026).
Pros:
- Automatic progress tracking
- Supports 3 platforms
- Lightweight and easy to set up
Cons:
- Fewer supported streaming sites than MAL-Sync
- No manga sync support
Manual Sync (Export/Import)
Both AniList and MyAnimeList support CSV export and import. This is the most reliable method for one-time syncs, but it doesn't handle ongoing updates. You'd need to export, import, and repeat every time you want to sync (AniList, 2026).
The Best Strategy: Pick One Primary Tracker
The most sustainable approach is to choose one tracker as your primary source of truth and sync the others to it. Here's the recommended setup:
- Primary tracker: AniList (best API, modern UI, flexible scoring)
- Secondary tracker: MyAnimeList (largest community, consensus scores)
- Sync tool: MAL-Sync extension for auto-syncing between AniList and MAL
- Kitsu: Use only if you want a cross-media (anime + manga) view
This way, you maintain one list that automatically propagates to the others. You avoid the frustration of managing three separate lists that drift out of sync (Reddit r/anilist, 2024).
Users on r/anilist report that MAL-Sync's bidirectional sync works well for status and progress, but favorites and reviews don't sync — you'll need to manage those manually on each platform.
Common Sync Problems and Fixes
| Problem | Cause | Fix |
|---|---|---|
| Episodes not syncing | MAL-Sync not connected to streaming site | Reconnect the extension and re-authorize |
| Scores don't match | Different scoring scales per platform | Use MAL-Sync's score mapping or accept the difference |
| Duplicate entries | Same anime mapped to different IDs | Use MAL-Sync's ID mapping tool to merge |
| Sync stops working | API rate limits or outages | Check AniList and MAL status pages, retry later |
The Bottom Line
Syncing anime watchlists across platforms is frustrating because the trackers were never designed to work together. MAL-Sync is the best tool for the job, but it requires setup and occasional maintenance. The most reliable long-term strategy is to pick one primary tracker and let MAL-Sync handle the rest.
Frequently Asked Questions
Can I sync AniList and MyAnimeList automatically?
Yes. MAL-Sync is the most reliable tool for automatic bidirectional sync between AniList and MyAnimeList. Install the extension, connect both accounts, and it will sync status, progress, and scores (MALSync, 2026).
Does Kitsu sync with AniList or MAL?
Kitsu doesn't have native integration with MAL-Sync. The best approach is to use MAL-Sync for AniList and MAL sync, and manage Kitsu separately as a secondary reference (MALSync, 2026).
Why do my scores differ between AniList and MAL?
AniList offers six scoring scales (1-5, 1-10, 1-100, etc.) plus sub-scores for story, art, sound, and characters. MAL uses a single 1-10 scale. Scores on AniList tend to run higher because the user base is more enthusiast-heavy (AniList, 2026).
Is there a way to merge duplicate entries?
Yes. MAL-Sync has an ID mapping tool that lets you merge duplicate entries across platforms. You can also use the offline anime database for automatic ID matching (MALSync, 2026).
What happens if AniList or MAL goes down?
Both services occasionally experience API outages. MAL-Sync caches your local data, so your lists aren't lost during outages. Check AniList status and MAL status for real-time updates (AniList, 2026).
