Title: UtilForge — Client-Side Developer Tool Matrix
Summary: A suite of 20+ developer utilities that run entirely in the browser. No uploads, no server, no data leaving your machine.
What I did: Built the full stack — Next.js frontend, Web Workers for heavy processing (formatting tens of thousands of lines of JSON, PDF manipulation, hashing) so the UI never blocks. Every tool works offline after first load.
Tags: Next.js · React · TypeScript · Web Workers Link: utilforge.dev

The no-upload promise is the strongest part. I'd make the offline state visible in the UI, so someone working with sensitive JSON or PDFs can see that the file stays on their machine before they drop it in.

Thanks! I actually already have a notice saying that files never leave the user's device. Maybe I should make it more prominent near the upload area so users see it before dropping in a sensitive file.
