About Pathine developer tools

Small utilities you reach for a dozen times a day and would rather not think about: read the token, format the payload, check the pattern, generate the id.

All of them run locally. That matters more here than elsewhere — pasting a JWT or a production payload into someone else's server is a habit worth not having.
