These are the small utilities that come up dozens of times a day when building or debugging software: making an API response readable, turning a timestamp from a log into a date, decoding the query string of a tracking link. Each one is a single page with no login and no clutter, so you can keep it open in a tab or find it again in two keystrokes.
All processing is client-side. Tokens, credentials and internal payloads you paste never leave your browser, which makes these safe to use with production data. The tools link to each other where workflows overlap — a JSON value inside a URL parameter, a timestamp inside a JWT — so you can move between them without re-pasting.
