Utilities

Tools

Small browser-local utilities. Each one runs entirely client-side — no data leaves your machine (except the P2P transfer, which routes directly between two browsers, never through a server). Free to use here. Check the owning source license before reusing the code.

Why these are here: I built them years ago for the original caseytunturi.com because I needed them and the alternatives all wanted to upload your files. They sat on a personal portfolio. They belong inside Samaritan — useful, free to access, and designed to keep ordinary work local.
