Interest Stacks

This an OVA and should be watched after finishing the UBW show.

This series is the prequel to Fate/Stay Night. It takes place 10 years before the events of Fate/Stay Night.] (the prequel is meant to be watched after finishing Fate/Stay Night and not before! People always make a mistake of watching Fate/Zero first, but that spoils plot events in Fate/Stay Night, so make sure to watch Fate/Zero AFTER finishing all of Fate/Stay Night.)

The series takes place 10 years after the events of Fate/Zero and 2 months before the events of Fate/Stay Night and revolves around the Clock Tower in the United Kingdom.

Even though it's a pretty terrible adaptation, it still at least has some portions of the Fate route you missed. It comes before UBW in the watching order. I personally wouldn't recommend it and would recommend reading at least the Fate route from the Visual novel instead, but the choice is yours. Essentially, this focuses on Saber, and if you like her character, I sincerely recommend reading the Fate route from the Visual Novel as the anime adaptation is not remotely as good, and is basically a butchered adaptation.

It's a cooking show with the main cast of characters from Fate/Stay Night. It's basically a slice-of-life show. It should be watched after finishing all of Fate/Stay Night.

Any other OVAs can be watched after finishing the main series I covered up there.

FGO -First Order- is the 74-minutes movie adaptation of the first chapter of Fate/Grand Order. Fate/Grand Order is a gacha RPG mobile game. FGO is not related to Fate/Stay Night. It's set in an alternate universe and timeline to Fate/Stay Night's. You should read the anime synopsis in the MAL link to learn more about the story.

In terms of story order, it happens before Babylonia. This movie will cover the 6th singularity.

In all honesty, you should play FGO to get the full story of the previous singularities because the anime doesn't cover them, and their intention is not to cover most of them because these adaptations are for FGO players who played the game and are not intended for anime watchers only. This anime covers the 7th singularity.

This movie will cover the 8th and final singularity.

Is an anime short OVA original story. It serves as a transition between parts 1.5 and 2 of the game's story.

Fate/Grand Carnival is the 2021 spin-off of Fate/Grand Order, similar to 2011's OVA comedy short series Carnival Phantasm, featuring loads of characters that now make up the roster of Type-Moon's Fate/Grand Order rather than just those from Tsukihime and Fate/stay night specifically. It's basically a parody show that takes FGO characters and puts them in ridiculous situations. I don't recommend you watching this one without having played FGO because a lot of jokes won't make sense to you otherwise.

It's not related to the main fate franchise and is set in a parallel world to Fate/Stay Night. It's recommended you at least watch Fate/Stay Night first before watching this one so you can be more familiar with how things work in the story.

Carnival Phantasm takes a number of characters from Type-Moon's original works and puts them in a variety of light-hearted scenarios which parody their respective series] - (It's advised that you read the Tsukihime Visual Novel or Manga and to have at least watched Fate/Stay Night as a whole to fully understand Carnival Phantasm.

This series is a Fate/stay night alternate universe spin-off that takes place in Fuyuki City and features Illya as the protagonist in an alternate timeline. You can watch the entirety of this show in release order, there is no special order for this show.

The universe of Extra shares the events of the Fate/stay night universe until a "certain major incident" happens and diverges completely.

The series is regarded as being set in an alternate parallel universe to Fate/Stay Night. They both share a lot of similarities in some of the plot elements. I won't delve into the details to avoid spoiling, but definitely check out these movies if you're interested in delving more into the Type-Moon universe.
