Developer Tools

Formatters, encoders, and generators for developers

The small tasks that interrupt actual work: making a minified blob readable, checking whether a pattern matches, encoding something for a URL, remembering what a cron expression means or what a 422 is. Each of these runs locally in your browser, which matters when the string you are pasting is a token or part of a customer record.
