The purpose of this repository is to create a dataset containing anime metadata aggregated by different anime metadata providers (such as myanimelist.net, anidb.net, kitsu.app and more) and allow cross-references between those metadata providers. This dataset is supposed to be used by and created for manami.
Important
After the 2025-25 update the dataset files will be removed from the repo and moved to releases instead. The reason is that this project is close to hitting the limits of github free plan and my assumption is that even git LFS won't last long under the free plan. There is a latest release available, always containing the most recent version of the files. Additionally named releases like 2025-25 are created which contain the files for that specific week.
Update week 05 [2026]
The dataset consists of 40482 entries (67% reviewed) composed of:
| Number of entries | Metadata provider |
|---|---|
| 29937 | myanimelist.net |
| 26606 | anime-planet.com |
| 21830 | kitsu.app |
| 20550 | anisearch.com |
| 20356 | anilist.co |
| 14290 | simkl.com |
| 14290 | animecountdown.com |
| 14275 | anidb.net |
