Developer Tools

About these dev tools

These are the utilities that end up in a browser bookmark folder: paste an API response and see it formatted, check a regular expression against real sample text, generate a handful of UUIDs, or dial in a box-shadow until it looks right. All ten run entirely client-side. That is a practical concern as much as a privacy one — API payloads, tokens and internal config regularly get pasted into formatters, and none of it should be sitting in somebody else's request log.

Every tool has its own page, its own explanation and its own worked example, so you can bookmark the one you use most instead of hunting through a tab bar. They all work offline once the page has loaded, they all work on a phone, and none of them ask you to create an account or wait in a queue.
