About

DevTool Desk is a collection of 41 small, focused developer utilities — encoders, formatters, generators, and everyday text, network, and math tools — brought together in one place with a consistent interface, so you don't have to bookmark a dozen different single-purpose sites.

Why browser-based

Most of the tools here run entirely client-side, using nothing but your browser's own JavaScript engine. When you format JSON, generate a UUID, or convert a color, that work happens on your device — nothing you type or upload is sent to a server. A handful of tools genuinely can't work that way (DNS lookups, HTTP header inspection, and similar tasks require a server to make the actual network request), and those are clearly noted on each tool's page along with what data is involved.

No accounts, no clutter

There's no sign-up, no paywall, and no artificial limits on how often you can use a tool. Favorites and recently-used tools are remembered locally in your browser via localStorage — that data never leaves your device and isn't visible to us.

Who's behind it

DevTool Desk is an independently run project, built and maintained with the goal of making fast, no-nonsense developer tools without the clutter, walls of ads, or dark patterns common on similar sites. If something is broken, missing, or could be better, see the Contact page.
