Rusteerio is a Rust-native HTML/XML parser exposing a Cheerio-compatible API via a TypeScript wrapper, with zero npm runtime dependencies.

It supports configurable parallel worker extraction (1–256 threads), streaming, and URL loading on Node.js 20.19+. Benchmarks report 4.5x speed over cheerio and 30x over jsdom on one CPU, with 1.7 GB peak memory versus cheerio's 7.2 GB at 16 CPUs.
