“If you need structured outputs from open models, Outlines is the correct solution. Not a hack, but a proper constraint system.”
“Solved server state management so well that it changed how React apps are built. The devtools are excellent.”

“TanStack Query's multi-framework support and the broader TanStack ecosystem are defining modern web data management.”
