utilnaut is a free collection of everyday utilities that run entirely in your browser — no account, no server, no data ever leaves your device.
From encoding and hashing to color pickers and QR generators, utilnaut covers the small tasks that come up every day in design, development, and general work. Every tool is instant, client-side, and free — no login required.
All processing happens locally in your browser. We do not collect, store, or transmit any data you enter into our tools. There is no backend, no database, and no telemetry on your inputs.
