scrutate's own source: Rust, Python and shell, plus a file in each language the index parses.
Your browser fetches the files straight from GitHub: up to 4,000 files and 60 MB, 1 MB a file. GitHub allows 60 API calls an hour without signing in, and each load uses one.
The files are read into this tab's memory and searched there. Nothing is uploaded: your code never leaves your computer.
