The Silent Sentinel: Rust-Powered WASM for Lightning-Fast Bot Detection at the Edge

on YouTube ↗40m

" summary

Claims a Rust-to-WASM bot detector that runs entirely in-browser, distributed via CDN and running on ~2 million sites, with WASM module cold load ~15 ms and detection latency under 50 ms; prototype starts in AssemblyScript then migrates to Rust using wasm-pack and a JS SDK with web workers and navigator.sendBeacon; backend uses Deno, SiciliaDB and Nuts event streaming; priority is low false positives and configurable bot threshold and client-side-only detection.
