Vercel Labs Ships scriptc, a TypeScript-to-Native Compiler That Leaves the JavaScript Engine Behind

Daniel Curtis — Fri, 25 Sep 2026 05:49:00 GMT

Vercel Labs has introduced scriptc, an experimental compiler that converts TypeScript into small native executables without relying on Node, V8, or a JavaScript engine. It uses the TypeScript compiler for type checking and can output C or WebAssembly code. Initial benchmarks show faster startup times and lower memory usage than Node, though it experiences slower execution speeds.

Building a Collaborative Platform Culture in a Bank

Ben Linders — Thu, 24 Sep 2026 11:09:00 GMT

A platform is a collaboration system, not infrastructure. Culture follows structure: platform teams can build open support sessions, create super user awards for contributing developers, and establish shared open standards to grow an engineering mindset. Developers and product teams depend on a platform team, which in turn depends on application teams; to go forward, they need shared standards.
