If you're hunting for legit places to read titles that used to show up on vyvymanga, I usually start with the publishers and big storefronts. Major Japanese publishers have official English portals: check
MANGA Plus (Shueisha), Viz Media's site and '
Shonen Jump' service, Kodansha's English site, and Square Enix's store. Those platforms often host simultaneous releases or official translations, and they’re the safest bet for current series.
Beyond that, I look at digital retailers and subscription services: BookWalker, ComiXology, Google Play Books, Apple Books, and
Amazon Kindle sell volumes. Subscription options like Crunchyroll Manga, Azuki, Manga Planet, and the paid tiers of 'Shonen Jump' can save money if you binge a lot. Don’t forget library apps too—
Libby/OverDrive and Hoopla sometimes carry licensed manga for free borrowing. If a title was a scanlation on vyvymanga, track the original licensor (Yen Press, Seven Seas, Vertical, etc.)—their sites will tell you where the series is officially available. I usually pick the official release that supports the creators; it feels better than a quick illegal download, and the translations often read cleaner in the official editions.
