Anime Ratings is a free Chrome add-on developed by StackedCrooked. This add-on enhances Wikipedia by adding MyAnimeList ratings to corresponding Wikipedia pages and lists of anime. It is a useful tool for anime enthusiasts who want to quickly see the ratings of their favorite anime series.

With Anime Ratings, users can easily find the MyAnimeList ratings for anime series directly on the corresponding Wikipedia pages. This eliminates the need for users to manually search for the ratings on separate websites. Additionally, Anime Ratings also adds ratings to Wikipedia lists of anime, making it convenient for users to get an overview of the ratings for multiple anime series in one place.

The add-on has gone through several updates to improve its functionality. The latest version, 35 and 36, includes a fix for authentication issues. Version 33 and 34 addressed the slow request rate to prevent triggering MyAnimeList's anti-flooding mechanisms. Version 30, 31, and 32 updated the code and manifest to support MyAnimeList's switch to HTTPS. Furthermore, the add-on now employs exponential backoff to slow down request rates if many requests fail.

Overall, Anime Ratings is a valuable tool for anime fans who frequent Wikipedia for information about anime series. It seamlessly integrates MyAnimeList ratings, providing users with quick access to ratings without leaving the Wikipedia page.
