Scratchpad

Every tool runs entirely in your browser. There's no server behind this. No database, no accounts, no analytics tracking what you paste. Your text goes into a JavaScript function on your machine and the result shows up on your screen. That's the whole architecture.

We built this because most online tools want your email before they'll format your JSON. Or they're "free" but your data takes a round trip through someone else's infrastructure. Scratchpad skips all of that. The code runs client-side. You can verify it yourself (View Source still works, we checked).

Works offline too, once the page loads. Airplane mode, sketchy hotel wifi, that one conference room where nothing connects. The tools don't care. They already have everything they need.

Ten developer tools right now. Formatters for JSON, YAML, and XML. Encoders for Base64 and URLs. A Markdown previewer that renders live. A hash generator using the Web Crypto API. A JWT decoder that shows you what's actually in your tokens. A diff tool for comparing text. And a regex tester that highlights matches inline.

More tools are coming. Text case converters, a lorem ipsum generator, data format converters (CSV to JSON, all that). Same deal: free, private, no sign-up required. Just tools that do their thing and get out of your way.
