WinterJS is a runtime JavaScript script developed from SpiderMonkey and written in Rust, which was recently announced four months ago. The project has now reached version 1.0 smoothly due to its compatibility with the WinterCG standard API and integration with Cloudflare APIs.
In terms of performance, WinterJS can handle up to 150k req/s in native mode, faster than Bun and NodeJS. However, when compiled as WASM, its performance is limited to only 20k req/s.
While it supports the WinterCG standard, many software developments are aligned with Cloudflare. As a result, WinterJS offers a Cloudflare mode for compatibility. This approach allows popular frameworks like NextJS, Svelte, Nuxt, Astro, Gatsby, previously ported to Cloudflare Workers API, to also run on WinterJS.
TLDR: WinterJS, a JavaScript runtime written in Rust, boasts impressive performance metrics and seamless integration with Cloudflare APIs, making it a versatile choice for developers using popular frameworks like NextJS and Gatsby.
