Rust React Compiler vs Babel: Is 10x speed real?

React Compiler’s Rust implementation is now available through Vite’s official React plugin and Bun, delivering substantially faster raw code transformations than the Babel-based compiler while preserving equivalent memoization output and runtime behavior. Testing on a 178-component React dashboard found that Oxc through Vite transformed 164 files about 19 times faster than Babel, but full Vite production builds were effectively unchanged because compiler work accounted for only a small portion of overall bundling time; Bun completed full builds about 8.8 times faster, although that reflects its broader native toolchain rather than the compiler alone. Vite users can enable the Rust compiler with a small configuration change and are encouraged to use the official plugin path to avoid known duplicate-React issues, while source maps and output quality appeared reliable in the evaluation. The performance advantage should become more noticeable in projects with thousands of components, where Babel’s compiler pass can add seconds, whereas Bun users should weigh its speed against larger bundles, missing default source maps, and immature TypeScript support.
