About developer tools
The small utilities every developer reaches for several times a day. Pretty-print a minified API response, find exactly where a payload breaks, convert JSON to CSV or YAML, encode a value for a query string, hash a file, test a regular expression, or work out what a Unix timestamp actually means. All of it runs locally, which matters when you are debugging with real tokens and customer records.
