Looks like a string of sites have shut down over fears about being unmasked and legal action being taken against fmovies, who were running most of the sites.
https://kaido.to/home is being discussed as an alternative. I am unfamiliar and can’t vouch for it at this time though.
https://4anime.gg/ still exists and works too.
Don’t use anime streaming sites just use nyaa.si and pirate episodes on the fly - much faster, better quality, and your choice of specific fansubs/etc!!!
Torrents (and especially that site specifically) have met all my needs for years. Good torrent software (like the free, open source qbittorrent), will let you literally stream the video just as well as a site, by downloading chunks in sequential order.
Stremio (the app) and Torrentio (the addon) brings everything to a single slick interface. It even tells you which (if any) streaming service the show you’re about to pirate is on, so you know who to feel smugly superior to.
Bless that site, been using it a ton lately
