You can watch Jujutsu Kaisen on several platforms other than Crunchyroll:

• Netflix : Available in many regions for streaming the first season and the movie Jujutsu Kaisen 0. However, Netflix does not have the second season in most regions, including the US

• Hulu and Disney+ : Both platforms offer the first season in the US, but not the second season. Disney+ is gradually integrating Hulu’s library, so availability may overlap

• Amazon Prime Video : You can watch Jujutsu Kaisen by adding the Crunchyroll channel to Prime Video or purchase episodes/seasons digitally. Amazon also offers the series for rent or purchase independently in some regions

• Funimation : Available in the US, Canada, UK, Ireland, Australia, and New Zealand, Funimation streams both seasons with subtitles and dubs

• Bilibili : For some Asian regions, Bilibili streams both seasons with subtitles or dubbing

• Apple TV, Google Play, Microsoft Store : These platforms allow digital purchase and download of episodes or seasons in HD quality

In summary, the best alternatives to Crunchyroll for watching Jujutsu Kaisen are Netflix (for season 1 and the movie), Hulu/Disney+ (season 1 in the US), Amazon Prime Video (with Crunchyroll channel or digital purchase), Funimation, and digital stores like Apple TV and Google Play. The second season is mostly exclusive to Crunchyroll and Funimation for now
