🥶 scriptc: Vercel's New TypeScript-to-Native Compiler A new entry into the growing field of JS/TS native ahead-of-time compilers that makes the promise that "what compiles behaves byte-for-byte like Node." Static by default, but you can opt in to a --dynamic mode which embeds a JavaScript engine for runtime dynamism. GitHub repo. Vercel Labs

😲 LiteParse 2: Fast, Light PDF Document Parsing A PDF parser built in Rust with bindings for Node (plus WASM, Rust, and Python) — it worked great in my testing. It includes OCR, handles layouts/is spatially aware, and is fast (a complex 140-page PDF took ~10 seconds). Here's how to get started from Node. LlamaIndex
