[EDIT] I typed "Router" when I meant "Query".
TanStack Query is the relatively newer name for React Query -- one of the most popular JS libraries of all time.
TanStack Start is a recent metaframework (and the one w/ the brightest future, IMO), but Tanner and team have profoundly significant bona fides. IOW, the dev team is far from being the "new kids on the block".
Are you thinking of the whole Remix/ReactRouter thing?
Thank you, but no. I typed "Router" when I meant "Query". TanStack Query is the newer name for the library FKA react-query.
TanStack Router is an alternative to React Router.
TanStack Start is an alternative to Remix/react-router-7's framework mode.
The naming history and evolution of react-router and its relationship to Remix is a bit convoluted, but an unrelated tangent to the point I was making.
React Router, which belongs to Remix, which was acquired by Shopify, is here: https://github.com/remix-run/react-router
Tanstack Router is an entirely new router.
