Where can I watch Ruby legally?
Right now, Ruby is on Paramount+ Amazon Channel. That said, anime licensing varies a lot by country — what's on Netflix in Japan might not be on Netflix in the US. If your go-to platform doesn't have it, try the other services listed above.
Is Ruby on Netflix or Crunchyroll?
Can't confirm either right now. Both platforms rotate their catalogs pretty often, so it's worth searching directly on each one.
Is Ruby available with an English dub?
Dub availability depends on the platform. Crunchyroll has been expanding their dubbed library a lot recently, and Funimation (now merged into Crunchyroll) historically had the biggest dub catalog. Check each platform's listing for Ruby.
Can I watch Ruby for free?
Crunchyroll offers a free ad-supported tier for some shows. Most other platforms require a subscription, but many offer free trials for new users. Tubi and Pluto TV occasionally have anime in their free rotation too.
