Seven tools.
One box.

Ctrl K

    ↑↓ move↵ openesc back

    Press Ctrl K on any page, type a few letters, hit Enter. That is the whole interface.

    An empty terminal window with a blinking cursor

    Nothing open yet.

    Type json, sha or uuid above and press Enter. The tool opens right here, full width, and your work stays put if you switch away.

    Where your input goes

    Nowhere. Every tool is a few dozen lines of JavaScript running in this tab. There is no server behind ntug to send anything to, and once the page has loaded it makes no network requests.

    1. 1

      You type or paste

      Text sits in a field on this page. Reload and it is gone.

    2. 2

      The tab computes

      Regex, hashing, parsing and conversion use your browser’s own engines.

    3. 3

      You copy the result

      Copy buttons touch the clipboard only when you press them.

    4. Network: none

      No fetch, no analytics, no web fonts, no CDN, no account.

    The seven

    Each one does a single job and says what it assumes. Open them from the palette, or jump straight to the full write-up.

    Why a palette

    Most developer utilities are a bookmark, a search, a cookie banner and a page of ads between you and a regex. ntug is the opposite bet: the tools are already on the page, the search is a fuzzy match over seven names, and the only thing it asks of you is a few keystrokes.

    It is also deliberately boring about trust. The code is plain files with no build step and no dependencies, so you can read it, save the folder, and run it from a disk with the network switched off. The privacy page tells you how to check that claim instead of taking it on faith.
