Show HN: Local-Sanitizer – Mask PII in 10GB+ Logs Locally Using Rust and WASM

Hi HN, author here.

I built this tool because I needed to sanitize server logs before pasting them into ChatGPT, but I didn't want to upload sensitive data to any 3rd party server.

It runs entirely in the browser using Rust compiled to WebAssembly. It uses a streaming parser, so it can handle huge files (tested with 10GB+) without crashing browser memory.

Happy to answer any questions about the Rust/Wasm implementation!
