Guillermo Rauch says scriptc, a TypeScript compiler, can beat Rust

Vercel CEO Guillermo Rauch says a TypeScript-based approach can outperform Rust, pointing to his work on scriptc, a TypeScript compiler he says aims to run faster than Rust.

In an X post on October 12, 2026, Rauch wrote "We can do better than Rust." The source gives no benchmark results or released version of scriptc.

In a follow-up cited in the same report, Cramforce describes type annotations that have no JavaScript semantics but let scriptc reject a function that may throw. He says scriptc already computes this check for optimized code.
