Developer Tools
Format, encode and inspect the data developers work with. · 3 tools
These are the small tools a developer reaches for dozens of times a day: making an API response readable, turning a timestamp in a log into a date, taking apart the query string of a tracking link. One page per tool, no login, no clutter — they can live in a pinned tab or be brought back with two keystrokes.
Format JSON pretty-prints, minifies and validates, pointing at the line and column of the first error instead of just saying "invalid". Unix timestamp converts in both directions between epoch seconds or milliseconds and human dates, in your local zone and in UTC, and shows the current time ticking. URL encode / decode handles whole URLs and individual components correctly, which are not the same thing.
All processing is client-side. The tokens, credentials and internal data you paste never leave the browser, so it is safe to use these with production data. Tools whose workflows overlap link to each other — JSON inside a URL parameter, a timestamp inside a JWT — so you can move between them without pasting again.
