About
gentoo.dev is a collection of the small utilities you look up mid-task — explaining a cron expression, formatting JSON, hashing a string. They run entirely in the browser: no accounts, no servers, nothing uploaded.
No server and no account. Input stays on your device — there's nothing to log, leak, or sell.
A static, installable site. Once loaded, the tools keep working with no network connection.
No sign-ups, no paywalls, no banner ads, and no analytics watching what you paste.
Every tool is JavaScript running on your own machine. You can verify it: open your browser's Network tab and use any tool — it makes no requests. Add the site to your home screen and it keeps working with the network off.
Built with Next.js, Material UI, and TypeScript; served as static files from Cloudflare.
