Meow is a new JavaScript runtime and toolchain that claims to be the fastest and most secure. It achieves this through features like full SHA-512 supply-chain verification on every install. Meow's performance is demonstrated through benchmarks, showing it can project a 516-package workspace from cache in 301ms and outperform other runtimes on real Next.js builds.

Opening excerpt (first ~120 words) tap to expand
// the benchmarks Fast where it actually counts. meow runs full SHA-512 supply-chain verification on every install — and still projects a 516-package workspace from cache in 301ms. On real Next.js 15 builds it leaves Node and Deno in the dust, and trades blows with the fastest runtimes on raw compute. On the work you actually ship, the claws come out. * 3 iterations · ~25+ pkg full-stack Next.js / Prisma workspace · real numbers, no shortcuts
Excerpt limited to ~120 words for fair-use compliance. The full article is at Meow.
