A calm collection of utilities, built for developers.
Utilive.dev is the kind of toolkit you keep open in a browser tab. JSON, regex, encoders, generators, formatters — all of it client-side, all of it free, all of it without ads.
How we build
We treat developer attention as a finite resource. Every tool is pushed toward the smallest, fastest, calmest version of itself.
Local-first by default
Every conversion, hash, and parse runs in your browser. We physically cannot read what you paste.
Fast where it matters
Minimal bundles, lazy-loaded extensions, and keyboard-first interactions. The toolbar is one click away.
Quiet, calm UI
A neutral palette, AA contrast, focus rings, and reduced-motion support. The tool gets out of your way.
Your browser is the server.
Tools run entirely on the page using standard Web APIs — JSON.parse, crypto.subtle, TextEncoder, and friends. There is no backend to ship your data to, and nothing to leak.
Open DevTools and watch the Network tab. You will see no outgoing request when you click Beautify.
