    My article about @wasmerio on FreeCodeCamp was published. In the article, I explain how to get a free domain and free hosting. Wasmer also supports more languages and frameworks, not only PHP.

    ⚡️ Edge.js can now run Node.js applications fully using QuickJS (including WebAssembly support!). Lightweight engine. Wasm sandboxing. Zero code changes. Blog post coming soon 👀

    🔥 Hot out of the oven: we ported Wasmer's 7-year-old Django backend to Rust. The result: • 220 CPUs → 24 • 800 GB RAM → 64 GB • p95 API latency: 120ms → 30ms • Query timings: 5–10x faster • Startup: >60s → ~1s Django served us well. Rust is powering what comes next!

    From "impossible" to shipped in 2 weeks 🚀 With Codex, we built Edge.js: full Node.js workloads running inside a WebAssembly sandbox at the edge (no Docker required!) The future of cloud is fast, secure, and WebAssembly-native.

    Edge.js was created with a secret weapon: @OpenAI Codex. 🤯We just compressed years of development work into a few weeks. Mind-blowing what we were able to achieve. The golden age of software is officially here! 🚀
