TanStack Redact trims React’s browser runtime

TanStack Redact 0.2.0 replaces React and React DOM in the browser without changing application code. Its stable integrations support TanStack Start, Vite, Vinext, and Next.js; with the latter two, React still handles server rendering while Redact takes over hydration and client rendering.

TanStack’s measurements show bundle reductions from 20.4% to 70.5% across its reference apps, but actual savings vary by project. The tradeoff is explicit: Redact renders synchronously, without React’s time slicing or interruptible rendering. A heavy render can therefore delay input, so compatibility and the busiest screens should be checked in each application.
